Hello all just had my 56 plate serviced and mot'd a few bushes and a couple of tyres later she passed. She came back with a new fault, she holds whatever revs I push the pedal. she will then idle on the redline, if I push in the clutch it will kill the revs for a moment then they will race again. Nothing is showing on diagnostics and it seems as tho the car has some Ill will towered me as she goes to pull away at junctions and holds herself on hills without the hand brake. She had her glow plugs replaced and the dashboard reset through a computer. I have no idea what is wrong but am annoyed at paying £500 for the work to have an undrivable car on her return. Please help at my wits end!

So the car showed the fault when you picked it up?

Also I must add I don't have my foot on the accelerator to drive once she gets to the right revs and she will travel miles like this

Yeah the mechanic mentioned it but it didn't occur until I was away from the garage now it's constant. It's going back there Monday but he has already had a look and can't find anything untoward

And they replaced the glow plugs and did what to the dash?

Do you have brake lights?

Fly by wire throttle pedal?

Where's moggy tech? Lol

Am not sure how a car can possibly hold itself on a hill unless breaks are stuck on?

Do you mean that your holding it on the clutch but without using throttle?

Does it shut off properly when you kill the ignition, or do you have to stall it to stop it running?

Tow it back to the garage it come out of?

It's starts normally and turns off normally I have a flashing glow plug light and engine management light on but these came on a while after the fault. It's like there's cruise control without the stalk it's the best way to describe it. She starts and stops normally on the turn of a key

TPS??

Sorry what's tps?

Would that b a throttle position sensor? Is that likely to wear with no warming and is it a costly job

i have exactly the same problem but after a while mine puts the abs braking system, power steering and traction control light on and cuts the speedo off really hoping you managed to find out the fault as im stumped

If you mean you can put it in first gear and release the clutch the car will creep along all by itself, Then all that is needed is to reduce the idle revs to about 10K, the skoda diesel lump is great for NOT Stalling

It is quiet handy sitting in traffic moving slowly,

on mine i can accelerate to 30 and take my feet off the pedals and it will sit at that speed and if i dip the clutch at that speed it will just rev itself around the clock and if i tap the brakeit drops the revs and then revs up again

Check that your brake lights are working.

You could also do some VCDS logs. Seeing what the throttle pedal position is.

10k!! It would have gone bang well before then!

You mean 1k now don't you

Is it possible crusie control can be turned on without a stalk present?

I very much doubt it!

Plus it would require that it was ignoring other sensors like the vehicle speed and pressing the the brake and clucth etc.

It sounds more like a brake or throttle issue to me.

Bit of a long shot, but saw this sort of thing on a 206 once, turned that had been overfilled with oil, quick check they didn't put too much in when they serviced it?

Good luck sorting!

Cheers

had a diagnostic done today and its come back as an abs fault either a speed sensor or the bearing but wouldnt say which is there anyway of finding out which wheel it could be without replacing all the abs sensors and bearing hubs
