Thanks to @Snake Charmer for rescuing the Daf after the engine failed. Was going to a Daf club meet, but it decided it did not want to go after all.

V1.0 given a SORN last night and V2.0 Taxed. Running the car last night I had a serious quantity of blue smoke from burning oil and the EML lit. Hoping it was oil residue from having been idled for hours on end I set off to work this morning with ESP and ABS  failure warning. First few applications of the brakes were poor but did improve, with no ABS you can screech to a halt on the Chinese tyres quite nicely. Engine also felt like no boost and in limp mode.

Stopped in a car park and ran diagnostics on the laptop,  ABS and ESP were down to the right rear sensor and turbo boost showing a  sensor fault. Both cleared now and normal service resumed, but the power is nowhere near V1.0. The left hand mirror indicator possibly has a dicky wire as that comes up occasionally on the dash  seems the smoke has cleared too.

Still hopeful for the Mot this evening if the smoke and lights stay out.

I don't bloody well believe it. Passed Mot emmisions, brakes and suspension ok plus it looks quite good underneath. Celebratory G&T anyone?

One week on and a few problems to sort. Mot was amusing, ABS and ESP lights stayed off after the morning reset but came back on after the Mot 😆. Car looks very good underneath and far better than the old one.

Had a go at removing the right rear ABS sensor and no joy in shifting it and have a nagging suspicion the reluctor ring may be at fault. Tried removing one from the old car and no joy then rain stopped play on the other side. Normally I would order a sensor and ring then have at it but as I have two good ones I will wait until I have time to test the faulty one properly before destroying what's in there.

Drives well enough despite a boost sensor and EGR fault so not very speedy at the moment. The steering wheel is off centre, a bit of alignment will be happening before a new set of tyres go on my 18" wheels but I will run the last couple of thousand miles off the existing tyres first. The shocks have just about had it, crashy over bumps and generally soft with full on seasick inducing wallow in all directions so the good suspension off the old car will go over.

Satnav is old hat now, miss the big Chinese screen but not the radio sound quality as the original is far better. At least I can still find my way to work and back.  After a bit of cleaning the interior smell has improved but still retains a light whiff of dags. Needs a thermostat as very slow to temperature as the old car was originally and the duo heater valve seems to be working correctly as I can get each zone at red hot or freezing cold at opposite corners.

Still not keen on the beige interior but as a whole not a bad replacement with potential.

I was a brave little soldier tonight, stayed late to have a butchers at the rear ABS sensors and  unnecessarily took both wheelarch liners out completely to access the sensor plugs and check their resistance. I was also curious to have a good look for any bodywork corrosion around the arches and sills, l can't believe it's 21 years old they are so good.

Left-hand brake pipe looks to have been changed, right-hand is on it's way, discs look barely worn and pads good. Resistance check on the ABS sensors shows them nigh on identical so l had a go at blowing all the dust and rust out of the hub. Did a reset and made it halfway to Sainsburys for beer supplies before tge ABS and ESP lights came back on so I'm ordering a pair of ABS reluctor rings and leaving the sensors alone.

Chances are I will get the hubs off only to find a perfect pair of reluctor rings and the right sensor has a broken wire!

I did the rear reluctor rings on mine, one side wasn't so bad but the other fought me while I was trying to get 4(?) arms off each side to get enough movement on the hub assembly to get the driveshaft clear. I hope yours goes a bit smoother or you know an easier way!

Thanks. Did you use original parts or aftermarket?

I used original parts, the rings were £14 each and in stock locally.  Merc rings of this era are a thin steel band with a rubber coating, not something I'd come across before. When mine went it put on quite a few dash lights and disabled the power steering, the rubber looked to have been hanging loose for some time but when I stripped the other side it was spot on.

Great information, thank you. In over 3 years of owning a Mercedes I have not visited a dealer for spares but have bought from them online. I should probably visit MB World at Brooklands and strike up a relationship.

I find even if you don't use them in the end it's worth asking , I've owned a couple of W126 and C126 and they're often competitive for bits . I sometimes use Mercedes of Newcastle through their Ebay site and even though they don't list stuff for my my 1985 500SEC  they'll come up with a quick price and availability, plus they post although it sounds like you already use this.

As above, I've bought quite a few bits from Mercedes for my W126 - Often cheaper than Ebay etc.

I decided in a drunken moment to order a pair of aftermarket ABS rings for £17 delivered, what can possibly go wrong? Nearly ordered a thermostat but thought a better idea would be to remove the perfectly good two year old 92°C unit from the old car.

Having made those monumental decisions, I found a small box of enthusiasm today and applied the whole contents liberally.

Good thermostat out in no time using my vacuum brake bleeder unit to pull a few litres of coolant as not being changed, doing the same on the newer car changing later in a major servicing frenzy seemed a good idea.

An interesting colour coolant came out, in my green bowl it looked like a mad TVR paint code, a mix of orange and blue coolant over the green shimmering in the sun. No dramas, no broken bolts and no problem holding a consistent 92°C now. I did snap the old temperature sensor off trying to remove it, l wanted to do an old and new thermostat comparison using the same sensor. C'est La Vie.

Black death looks non existant and all dry around the injector area, swapped in the missing sound deadening foam and felt. Now wondering if leaving that out effects injector cooling leading to seal failure.

Swapped the spacesaver over as that has a new valve, added the missing warning triangle. Changed one of the broken floor panel handles, then gave the load area and spare wheel well a good vacuum.

A bit of soldering was order of the day swapping the ATA tilt sensor black box over as the original has suffered being sprayed with washer fluid from the bidet hose joint popping.(Added the anti-bidet-joint-spray colostomy bag for peace of mind.)

Finished off in the load area by straightening the big stainless step plate out where extra wires have been stuffed under for the towbar and clips broken. That wiring will need another coat of looking at when the towbar is swapped over. 

I might have shorted something on the alarm side as the fob radio door locking failed, only locked via infrared as F8 7.5A fuse had blown in the rear SAM. Found that out on the Tesco cider run, had to use the poxy key in a panic as they were nearly closed! (I'm not ruling out the alarm siren having gone titsup, I have set it off and thieves would just laugh at it.)

Out on the road the car feels smoother running a consistent 92°C and the mpg cruising at 60mph on the motorway is definitely better than the old car ever did resetting on the move. (If to be trusted.) Shame there's no noticable turbo boost and torque like the old car, that's next on the hit list and l suspect the odd clicking being made by the turbo actuator is the likely suspect. 

Could not be arsed swapping and cleaning the 18" wheels.
