Barefoot's Rover 75 update

Recommended Posts

That is Chodweavers access port I think - saves so much hassle. 

 

I didn't dare cut a mahoosive hole in the boot - that was a PO's doing - I just couldn't cope with it having been done with a tin opener and then closed up again with sharp edges, rivets, self tappers and seam sealant.

 

So I closed it up with more metal, self tappers and draughtproofing foam instead iirc.

So, Saturday morning, I brimmed the Vel Satis with fuel for the week ahead and popped out to take the fair wife & the dog to agility class

- see the wife rattle though those tunnels etc.

 

Pottering along, not exerting the car in any way shape or form - and the engine management light comes on.

The car drives no differently.

Arrived at dog school, attached code reader, it's a P0420 code - again.

Oxygen sensor not operating at peak efficiency - I'm not surprised - it's done 260,000 miles.

Code deleted.

The dog ran around like a good 'un and then we set off for home.

Bugger me, 'Electronic parking brake faulty*' light comes on.

My cheap code reader can't see or do anything with this.

The EPB works exactly as it did before, but the fair wife won't go to work in it - and fairly so since according to the handbook the * means

'and may fail and render the fucking Renault immoveable' like it did once before.

 

FFS - Sunday morning, brimmed the Scirocco with fuel for the week ahead...

 

I'll be ringing me renner licking garage chum at dawn in the morning.

My favourite Renner licker - Nick is sorted the VS.

 

He's replaced the leaking turbo oil feed pipe - which will stop the fair wife smelling like a rigger when she returns from work, 

And he appears to have found a fault with, if not a solution to; today's handbrake problems.

 

In my excitement with it faiiing yet again, I may have forgotten to post that it was a;

 

 

204 - Application Value Not Reached.
Taf, my specialist Welsh mate informs me that this means that at some point, it's applied the brakes and subsequently detected movement at the wheel & squeezed them on a little more. He reckons that this will be caused by either; stretch in one of the cables which will need tightening/shimming a bit more. Or a lazy calliper. He says that with the car on the ramps & both rear wheels off, you should be able to see which side is slow.
 
 

It was none of these things, it was in fact, curiously uneven wear in one of the inboard brake pads.

Check this out, I've only had the car a year and have had the rear pads/callipers replaced relatively recently.

Any ideas with what's going wrong here?

 

Runs and parks up like a good 'un again.

Crusty calliper carrier where the pads sit. Usually need taking off the car every so often and cleaning up with a grinder so the pads can move freely.

If not, the pads will wedge themselves in and refuse to release from the disc when the brakes are released.

As you can probably imagine, the 'EPB FAULTY' warning is back on.

I checked out the intergoogles and found not one, but two Renner specialists within about ten miles.

The first one has only ever seen one VS and doesn't understand how the EPB might need adjustment.

The second is very busy but has booked me in at 15:00 on the 15th.

I am intrigued to say the least!

In the meantime, I borrowed a clever code reader - 204 - insufficient tension - again.

Code removed, warning off, the fair wife will be back in it tomorrow.

 

Hippy new year.

Pottered over to Loughborough Market in the Jaguar this morning, on the way back as I turned onto the new Kegworth bypass, I realised I was totally on my own, so I flicked the old J gate into the position I have come to call '3rd', and firmly pressed the loud pedal. I wafted up that smooth new empty road like fuck. It's not an amazingly fast car, but it is so silky smooth and the V-8 does make its presence felt above 4,000 rpms.

 

That's it; just a gratuitous, rapid waft.

Back to the Vel Satis and after having the EPB warning extinguished recently, I've been to a specialist today to have the codes interpreted.

This involved a 4 mile / 30 minute crawl into Long Eaton to Diamond Motors where a very nice chap plugged in a whole computer and ran the car through all manner of tests. These determined that the electronic bit was working perfectly - I should fucking hope so it's almost new - and that the problem, 'application value not reached' - was due to a mechanical problem. Callipers/cables/pads all new - chap did the only decent thing and suggested that the scored discs were to blame. New pad + scored disc = insufficient force. It detects movement when parked on a slope and tries to pull on a bit more.

Obviously the wear means that it'll never achieve the value that its parameters tell it to aim for.

 

Well, it looks like the bastard isn't going to lock on any time soon, so I'll price up some discs for a laugh and just delete the code every time it pops up.

Hmmmm, I was thinking of it the other way.... "application value not reached" to me means "I asked for 100% brake force but the pads only moved 50%" or whatever. Surely if the disks were crap then it would reach the application force asked for, but the car would just roll.

 

I dunno. I'm only guessing, same as he was. Error codes might as well be in latin.

It pulls the 625 or 1500 newtons as requested - short tug or long pull

But the pads can't make 100% contact on the fucked disc so later as the discs cool & contract the car will move very slightly and the brakes will attempt to tighten up to prevent the movement. This is how/why it thinks its not achieving the correct value.

I suspect that the short term solution is to switch off the car - which will apply the brake. Put it in gear, release the brake, let it roll and then re-apply so that it won't be able to roll any further. All I have to do now is explain this to the fair wife over a cup of tea & biscuits.

Oww, Renault EPB!  I still have the occasional nightmare...

 

I bought a clone Renault CAN Clip tool to diagnose mine, when I had a Scenic II. And while the possibility was jokingly brought up earlier, mine actually did perform the 'Engage Full-Powah 1700 Nm! and subsequent NO CAN HAZ RELEZ SORRY' routine. Luckily on my driveway... but at a very inconvenient time just when I was supposed to pick up banger jr #3 from kindergarten. I sheepishly hollered the neighbor whether she'd be kind enough to lend her car for a bit.

 

The Scenic ended up spending a couple of weeks on the driveway while I tried to sort out my options. The scanner complained of an internal motor fault, if memory serves right, so in the end I had to order a new EPB unit (crazy money) and cut both parking brake cables with a bolt cutter to free the bastard. The local Renault dealer, however, was unable to program the new EPB unit on the fecker. I was able to warranty the DOA unit, but the replacement unit, while accepted by that proper snowflake of a car, continued to persist with a "Check parking brake" error up till I sold the car.

The fair wife seems happy with the diagnosis from the specialist, that the warning light may come on but is not a warning of imminent parking brake stuck on catastrophe as happened to her previously, and is essentially just a disc wear warning that can be reset by local bloke with scanner.

So would you all cough up for new discs at £140 plus fitting & 'calibration' by specialist, or just leave it?

I'd be very conflicted.  If a car has something, I like it to work as intended.  Then again, this whole EPB is the answer to a question nobody asked anyway - so if it's "working" then I'd probably disregard.

 

Forgive me, I'm not familiar with the situation.  Do you have another 'turn key' vehicle she can just jump in if the worst happens at home?

Even in the event of complete electronic meltdown, the manual hand release should mechanically release the brakes. Providing that cable hasn't snapped and the brake cables haven't seized. Which shouldn't be a problem on the Vel Satis.

 

I believe the EPB electrically never goes to sleep. So if the car starts moving, it will actuate the handbrake stronger. I assume it's not something like the cables aren't too long, so it can't get full range on the caliper?

Me too!

 

And yes, she can take the Scirocco which is on winter tyres too.

When it did have complete meltdown, it was out of the blue and I hadn't told her about the emergency release handle - it's not something you would normally mention to the wife!

You are correct about the non sleeping EPB, the cables have both been adjusted/shimmed to exactly the correct length. The scored discs (& they are badly scored) are the only thing left to replace.

Does this code come on when you come back to the car then?

 

I wonder if autos have less EPB problems? As they are usually in park when left, locking the transmission thus not likely to move.

 

Do you leave it in gear when parked up?

Yes. The fair wife normally leaves in in gear, I don't but have started doing so.

Ideally I suspect that I should stall it as I switch off to ensure that there's nowhere for it to move!

Not quite. For myself I'd splash the cash on the parts and be pissing about at vast expense buying* the tools to fix it myself and moaning about rolling around on the ground in the cold.

 

But like BorniteIdentity, for good or bad, if a car has a feature or something, I make* it work, rather than put up with warnings that'd twist my melon. I usually justify the cost because I don't lose* money as I always keep cars.

The fair wife returned home last night reporting a cracked windscreen.

It's about six inches long, towards the bottom.

 

Now seems as good a time as any to to see how good Aviva/Autoglass are at replacing broken glass...
