Mercedes Benz - W123 230E & W124 200E - Both happy and working ok


Peter C

Recommended Posts

A quick update on the 230E. It's been out on a few local journeys with no problems to report. The taxi sign continues to attract a lot of attention and a number of people have stopped for a chat, asking whether it's a real German taxi. I consider the taxi sign as jewelry, like a giant diamond butt plug perched on the roof.

For ICE I use a JBL portable speaker, Bluetooth connected to my iPhone. The original Becker radio cassette player and electric aerial are in good working condition, however I like my DAB. As part of my maintenance regime I refresh the grease on the aerial mast every year.

A few weeks ago the 200E's starter motor developed a screeching sound. It only screeched when the engine was first started, subsequent re-starts were silent. I got in touch with Mike at JASM and he's willing and able to give the starter motor a refurb. This is just as well as looking on AutoDocs and ECP's websites and on EBay brings up multiple listings for W124 starter motors, with contradictory results. Id rather have mine fixed rather than spend anything from £50 to £150 on a part that may not fit.

One last action shot of the 200E, I needed more decking boards and what better car to collect them with than the 200E.

I removed the starter motor yesterday. I got the front of the 200E high on ramps, which gave me plenty of room and comfortable and safe working conditions.

All the action took place from underneath the car, neither the starter motor nor the wiring are visible from within the engine bay. The starter motor is secured with two long bolts, which were easy to access and remove. The bolt and screw that secure the wiring could only be got at once the starter motor was unbolted and rotated in-situ. As I only have two hands, both of which were needed to remove the nut and screw, I used a piece of wood and a jack to wedge the starter motor up against the floorpan.

I got the starter motor off, it was surprisingly light and small. There is no identifiable Mercedes Benz part number on it, however the Bosch part number is nice and clear. Hopefully reinstatement of the starter motor will be less faff than removal.

  • Peter C changed the title to Mercedes W124 200E - Rolling Resto - Now with W210 content

The 200E is still up on ramps in the garage whilst I wait for JASM to refurbish the starter motor.

I have added a 1999 W210 E240 Avantgarde to the fleet. It has 129k with FSH, which comprises of a fully stamped service book and a stack of receipts and old MoT certificates. Not all receipts are in place, for example the previous owner recently fitted new front brake discs and pads, of which there is no record in the history. Never mind. It's got three (electronic) keys, two of which work, one allegedly needs a battery.

It's my ideal spec, post facelift saloon, silver, black interior. The previous owner fitted period correct CLK alloy wheels, which are in decent condition and have four as new tyres, a pair of Continentals up front and Events on the rear. There's also a matching spare.

Being a W210 it's going to have rust issues. The previous owner has had two jacking points welded and there are localised blisters appearing under the paint along the front and rear wheel arches. It's not too bad, at least not yet but it looks a lot better than some W210s that I have seen. There is a small crack on the front bumper and the front end has been touched up where it picked up stone chips. The headlights are not cloudy and the exterior trim is unmarked. Overall, I'd give it 8/10.

The interior is very tidy and well specced. We have leather seats, the fronts are electrically operated, electric windows and mirrors, the latter fold at the press of a button, cruise control and air conditioning. There is virtually no wear on the leather seats but the floor mats that came with it were horrible and didn't fit right. I binned them. I will buy a cheap bespoke set from EBay. The air conditioning doesn't work but that doesn't bother me, I suffer from sinus issues and never use it anyway. The boot is big and tidy, it's got all the original tools and warning triangle and first aid kit is in place (in the rear armrest). Overall, I'd give it 9/10.

I noticed yesterday that the offside rear alloy wheel has a polished outer edge whilst the other three wheels are all silver. Not an issue as far as I'm concerned.

11.thumb.JPG.9f2272460d86bffd3bbe915692aebda7.JPG

The V6 looks quite small in the giant engine bay. The bay needs a clean but  as the E240 will be used daily in all weathers I'm not going to get too precious about it. The engine starts and runs well. It's very smooth and quiet but not as smooth as the gearchanges, which are virtually seamless. I was surprised by the high gearing. On the motorway, at 70MPH the engine is spinning over at 3,000 revs/min, which is high. I recall that the W126 300SE that I had years ago had similarly high gearing, although that had a four speed automatic gearbox whilst the E240 has five.

12.thumb.JPG.9194d3b3f6b8344535abd34bb490db64.JPG

So far there is only one issue that requires attention. Driving at low speeds or whilst stationary, I can feel slight friction and a rubbing sound when the steering wheel is turned. At first I thought it might be dry ball joints. I've had various Mercs in the past that suffered from the same problem and displayed identical symptoms. I took the front wheels off and squirted some engine oil via a needle and syringe into the top and bottom ball joints. I used a small needle, which won't cause any significant damage to the rubber covers. Unfortunately, the procedure did not improve the situation.

14.thumb.JPG.75b87d292c4d3278ecfcccce79338045.JPG

A bit of research on the internet revealed that there is a rubber seal at the base of the steering column, inside the cabin, which can get dry and cause the reported symptoms. I will have a go at greasing up the seal later today.

With the front wheels off, I could see the new brake discs and pads, which is a bonus. Not so good is the rust, which affects most surfaces. W210s, you gotta love them.

It's a shame about the rust situation on these, because they seem pretty good mechanically. The styling is slightly gawky, the front treatment was ok but the wheels never seem to fit the arches properly.

I agree. The styling is a bit Marmite, the front end curves are let down by a square rear end. I still like it, especially in (boring!) silver.

I had a bit of time this morning to take a look at the steering column seal. Getting to it involved removal of the lower dash panel and footwell carpet. All very easy, the interior is really well assembled.

16.thumb.JPG.909bb491dacfd15af6ff2d339e8f478b.JPG

Unfortunately, I found the seal to be perfectly well lubricated.

17.thumb.JPG.4fe4ad69846f0bad8c996cd4f592e59d.JPG

I did more sniffing around and noted that the groan only occurs when the engine is switched on and the steering wheel is turned slowly. With the engine switched off, there is no noise. Driving at normal speed the steering is just fine. I came to the conclusion that something inside the steering rack is not happy. I drained approx 400mm of power steering fluid and poured in the same amount of Slick 50. I am hoping that by reducing friction within the rack the noise will stop. There was no instant improvement, however research on the internet suggests that these types of additives can take approx 2 weeks to work. The car drives absolutely fine, with the radio switched on the noise cannot be heard and worst case scenario, the noise only occurs at parking speeds and is not overly intrusive. The plan is to live with it and see what happens.

18.thumb.JPG.d1067ddb1483d551f3bb80467e4c4447.JPG

I know I said that I won't get precious about the presentation of the engine bay, however I managed to spill some of the Slick 50 and it dripped all over the auxiliary belt. I tried my best to clean the mess but as soon as I started the engine, drops of Slick 50 ended up getting flicked all over the front of the engine. I removed the top cover to find leak free cylinder heads. 

19.thumb.JPG.ab6604057d45b20ed00d7c836f4ce8fb.JPG 

I spent 20 minutes with wet wipes and achieved a tidy engine bay.

In other news, I was not too bothered by the incorrect designation but the spacing of the digits was all wrong and looked shit.

21.thumb.JPG.cd95ee5a96d1b56cd4476b5f21b94944.JPG

A little heat got the adhesive soft and the digits came off without leaving a mark. Much better.

Not one to give up easily, I had another go at sorting out the steering rack noise. I got the front of the car up nice and high.

23.thumb.jpg.c9cc0aa7f916e8cc144de0db0f5ab45a.jpg

I removed the steering rack gaiters to reveal the rack. On the nearside, the rack was shiny and silver. On the offside, around the teeth that mesh with the pinion, there was a fair amount of surface corrosion. Fortunately / unfortunately, the rack seals are good and there is no evidence of fluid leakage. I squirted silicone spray onto the rack whilst my wife was turning the wheels from side to side and finished the job off by applying fresh grease before putting the gaiters back.

24.thumb.jpg.0a6709b9bcd655070f7509b9a7ab553e.jpg

I went for a drive around the block and sadly the noise is still there.

Evidently, something is binding inside the rack. However, with the outer seals / bushes intact, there is no way of getting any fluid or grease to lubricate the offending surfaces. 

25.jpg.570e2ce9f45a773af74469448c4adee3.jpg

A replacement reconditioned rack is £145. Then there's postage, cost of new fluid and having the geometry re-set. There won't be much change from £250 and that is assuming that I can complete the job in my workshop. As the chances of me putting the rack back in line with the column in exactly the same position as it should be are extremely low, I expect there would be a need to remove and align the steering wheel before the geometry can be fixed.

I can remove the rack, the job doesn't look too daunting (there's a nice YouTube video that really helps) but what chance do I have of getting into the innards without special tools? And if I do strip it without renewing the seals, how long will they last before the rack starts to leak? 

I'm not sure what to do.

Nice purchase, if you can be bothered would be an interesting evolution photo w123-124-210 

Will do but first I need the 200E’s starter motor back from JASM. Until then it’s stuck in my workshop.

230E update first, whenever the weather permits, I take it out on trips to all sorts of lovely places, such as the industrial estate in Iver (near Slough), see photo below! 

Since I started using the 230E more often, I've noted that the brakes pulled slightly to the left. I presumed that there might be air in the front nearside brake pipe / caliper or the caliper was getting a bit sticky. The other day, whilst approaching a totally clear roundabout, driving behind a Fiat 500, the cinquecento came to a needless complete stop, forcing me to slam my brakes on. The front wheels skidded a little, I shat myself but the 230E came to an incident free stop. Since then, the brake pedal feels firmer and the brakes pull up straight.  

679.thumb.JPG.4f766237718baa4528249ef795948e0f.JPG

200E update next. The 200E has been stuck in my workshop whilst Mike at JSMA was overhauling the starter motor. The fresh and clean starter motor was returned to me this morning, the plan is to refit it and have the 200E back on the road tomorrow. Wish me luck.

680.thumb.jpg.e9d2830f2b82cb9bcf42bf8b8d285b2d.jpg

Finally, the W210. It's with my mechanic in London. I did all I could to diagnose the cause of the creaking / friction in the steering wheel and I've run out of time and patience. A few people have suggested that the PAS pump could be the culprit, which, if proved correct, would be less of a pain to replace than the steering rack. Watch this space.

Same here.  My ideal would be a LHD 300 turbodiesel estate with the OM617 TD unit.  Unfortunately these are now £FUCKME expensive.

LHD because the RHD models weren't available with a turbocharged engine and the N/A OM617 is a tadge slow.

I went to see one of these at a local garage a few years ago. It was utterly fantastic - first owner was from up the road and imported it himself so he could have his perfect* car. 

It was £8k vs £3.5k for a NA RHD car, and I thought he’d have it for sale for ages because niche market. 

It was gone the next day!

You can get 100mph (down a hill) out of the N/A 300D engine, but this is the resulting “emissions deposits” 🤣

Buy a petrol powered W123 and problem solved. My 230E will manage 100MPH without breaking a sweat.

  • Peter C changed the title to Mercedes Benz - W123 230E, W124 200E & W210 E240 - All back on four wheels and running ok

230E update.

My mother in law (lovely woman) made a cover for the taxi sign. She made it from waterproof fabric and two velcro straps so it should last and stay put. I will keep it in the boot and have it ready in case a jobsworth copper pulls me over.

681.thumb.jpg.d2309e6a1927baacf43d0ad144e8bdde.jpg

200E update.

I got the starter motor back from Mike at JSMA. At £75 is was half the price of a new unit but once you factor in postage costs, it didn't work out much cheaper.

Re-fitting it was fun. Access cannot be gained to re-fit the cables with the starter motor in place. I suspended the starter motor by string fixed to the bulkhead and whilst my wife, lying next to me under the car, held the starter motor in place, I just about squeezed my arms in and put the cables and fixings on the terminals. With the cables on, re-fitting the starter motor, which is secured with two bolts, took a couple of minutes.

I fired up the engine and I am pleased to report that all is well, the refurbished starter motor is silent again. 

E240 update.

Having done all I could outside my workshop (with the 200E up on ramps and without a starter motor parked in the workshop), I left the E240 with my mechanic in west London. He did all the same checks as me and confirmed that the ball joints and steering column grommet were all ok and the cause of the friction and squeak was either the steering rack or PAS pump. Fortunately, he is not one to start replacing parts one by one until he eventually finds the fault. We discussed my (limited!) options and agreed that before I start spending serious money, he will drain and renew the PAS fluid. A couple of weeks ago, when removing some of the fluid to make space for the Slick 50 additive, I could see just how dirty (black) the old fluid was. My mechanic flushed out the old fluid and refilled the system with fresh red fluid. And.... the problem is 90% fixed. In normal driving the rack is silent. Only when driving very slowly, at parking speeds, whilst turning the steering wheel very slowly, I can hear a very faint sound coming from the steering. Under all other conditions the steering is silent. Job done. 

I went to collect the E240 today, it was good to see it in the flesh again. Such a pretty car, beauty being in the eye of the beholder. 

26.thumb.JPG.4825e8e57ac058c5bfa72dc7abc76b8a.JPG

Unfortunately, my mechanic always returns my cars in filthy condition, both inside and out, which is annoying as I gave the interior a deep clean before I took the E240 to him.

27.thumb.JPG.2d1e6e3813577c30eb155fb5e540cc61.JPG

Nothing that a wet wipe and hoover couldn't fix. I ordered new (bespoke) floor mats via EBay and I am pleased to say that they fit just great and complete the tidy interior.

28.thumb.JPG.b9bb24e8c1f2b5989dfc8ac03cc22863.JPG

Under the bonnet all is well. My mechanic renewed the auxiliary belt, as the old one was frayed. 

29.thumb.JPG.3f8bc0819d8e9b4d24d51c84060798a9.JPG

I gave the E240 a quick wipe over and left it out in a prime position on the drive next to my wife's Tucson. Of the two integrated garages, a car only fits in the left side  garage and the 230E is parked there. The right side garage is our utility area. The 200E is parked in the workshop, located to the left of the house. My Kia is now parked outside the workshop, behind solid timber gates, out of sight. To a passer-by, we look like a normal two car family. I could but really don't want to park any cars on the lawn. Saying that, a W211 and a W201 would really complete the collection. Hmm.

More E240 fun and games.

Every so often the dash display would warn me that my reversing lights have failed. It wasn't lying, the reverse lights were knackered. A bit of research on the internet and I found this: 

https://forums.mercedesclub.org.uk/index.php?threads/e300-w210-intermittent-reversing-lights-sorted.45900/

Getting to the famous grey cable wasn't difficult.

31.thumb.JPG.b28beb99fabe1fe479196c221d3af347.JPG

Having provided a reliable +12V supply to the reverse light switch, I now have working reverse lights and no more malfunction warnings. Result.

32.thumb.JPG.b9cd35dbde65a2d9405feb9c0aeb9f92.JPG

I removed the tape adapter and fitted an FM transmitter, which I originally bought for the Audi TT. It works ok, I don't have any cables dangling on my dashboard and I can charge my iPhone whilst playing music. Result.

33.thumb.JPG.09ec65b3d19fd1b1fc5d4f4733e6f1bd.JPG

Whilst buying the car two weeks ago, the previous owner told me that the spare wheel and tyre are in good condition. I didn't bother checking, until today. He wasn't wrong!

  • Peter C changed the title to Mercedes Benz - W123 230E, W124 200E & W210 E240 - Which one managed 39.8MPG?

Four days after buying the E240 I handed it over to my mechanic to sort out the noisy power steering issue. Since getting the E240 back, I've only been down the shops in it twice. Until today. I took the E240 or a 101 mile round trip to Croydon and back, via the M40, M25 and A23. It performed superbly, the engine is so smooth, especially compared with the thrumy 3 pot that I have in the Kia and the automatic gearbox is amazing, it's without doubt the smoothest shifting automatic 'box I've experienced in a Mercedes Benz. 

Admittedly traffic was light but even so, the E240 achieved 39.8MPG, which includes climbing some pretty steep hills in the Croydon area. Without the hills I would have seen 40MPG. Without the hills and side roads, on a long motorway run, I wonder if I would see 45MPG. Not bad from a 2.4 litre petrol V6.

38.thumb.jpg.ea23bb3ed024789cbd534f0edceb8f17.jpg

For bonus points, when I arrived in Croydon, the person (work related appointment) I went to see had a lovely W124 E220 cabriolet outside his house.

The trip computer wasn't lying. I've been driving the E240 around some more in the past few days, including in a bit of traffic and I always let the engine idle for a minute or two before setting off in the morning. I brimmed the tank today, having clocked up 190 miles, it took just under 22 litres to fill the tank, which equates to approx 33MPG. No doubt with a heavier right foot and inner city driving that figure would drop massively but that's not what the E240 is about.

  • Peter C changed the title to Mercedes Benz - W123 230E & W124 200E - Squeaking fan motor - fixed (hopefully!)

This time last week @Agila collected the E240. I sold it because it was too comfortable, smooth and easy to drive. I was hoping that a V6 powered Avantgarde model (with sports suspension) would have an edge to it but sadly not. I enjoy owning and driving my W123 and W124 far more than the sterile W210.

Earlier this week I drove the 200E around the M25 to east London for a work appointment. It was the second hottest day of the year so far and shortly into the journey the ventilation fan started to squeak. Bugger. 

Before starting the job I did a bit of on-line research to see how best to tackle it. There's an informative YouTube video presented by an Australian chap, however quickly into the process I discovered that my bulkhead trim and fan construction is very different to the car that he was working on.

The good news is that getting to the fan motor does not involve removal of the dashboard. The bad news is that the fan motor is hidden deep behind the bulkhead.

682.thumb.JPG.adc36542f9dcd7efb7e78326dfe6fecb.JPG

To get to it, all this needs to come off.

683.thumb.JPG.eb6312a75320ab23ee0c42f6e27f648e.JPG

And here it is.

685.thumb.JPG.c5bad89b07dcfd91d4e049a8c3faf063.JPG

With the fan motor removed, it was obvious that access to the rear bearing could not be gained without removing the plastic fan.

686.thumb.JPG.68ce656a6d9d0a281a85b11a692b24ec.JPG

I used a puller to remove the plastic fan.

687.thumb.JPG.3ae8ec0a4fee266419081af2b9a1f37e.JPG

The recommended lubricant for the bearings is PAS fluid. Luckily I had some and using a syringe I managed to apply it directly to the bearings without getting it all over the motor assembly.

688.thumb.JPG.9c81415f7f2895f84f12aceffa2e8bc1.JPG

Once lubed up, with the fan motor secured in a vice, I knocked the plastic fan back onto the shaft with the help of a suitable socket and hammer.

689.thumb.JPG.ee3aadc8992ef0edd08aff76a13f01f8.JPG

I am pleased to report that the fan motor is now silent and the wiper motor, which I had to remove to get to the fan motor, works as it should. I am aware that lubricating the old bearings is not a permanent fix, however at least now I know exactly how to do the job if it needs doing again and which fan motor I have.

Classic Car Night at the Ace Cafe. It’s a beautiful warm and most importantly dry day and I’m here with the 230E.

I’ve arrived early to ensure the 230E got a good spot and to have a bite to eat before the kitchen gets too busy.

The Consul owner lives near Hendon School, and the car is a familiar sight around here.

I'm surprised that blower motor fan blade assembly pulled off the shaft without breaking, I didnt even attempt to do that on mine (still have the old one though, might be salvagable after all!). Much easier to get out in the W140 as well.

Piece of piss, the fan blade came off very easily but admittedly I did make use of a suitable puller.
