Hi again, one problem after another. To be  honest, the Fabia has not been out for more than half a dozen times in the last 2 years. Recently had probs with engine, but now fixed.(see last post re crankshaft sensor).

My problem now is, when I start the car, the revs settle at approx 1500rpm, if I toe-lift the pedal the revs drop to 900rpm. This is not much of a problem, but, it is catching me out when driving ie. when slow driving at junctions.....sometimes it doesn't slow down.

What I can gather from the net, is, it is a drive-by-wire/potensiometer thingy ma jig. I'm thinking (fingers crossed) that due to lack of use, it maybe has gone stiff.

My question is.. how do I remove & clean (if possible) my accelerator pedal. '56 1.9tdi 130pd.

Thanks in advance.

Throttle pedal position sensor. Failed on my 1.2. Just lob the old unit off (three bolts, maybe four), get the part number, and send away for a second hand one from a breakers, mine was £15. Have done about 6k since I replaced mine and it's running like a wee sweetie.

 

 

@Pete_Ex-Wino got my old failing one for research purposes. He might be able to tell you if it's possible to fix them. Until then, I'd recommend just replacing it.

 

Hope this helps.

I didn't find any obvious problem with the one you kindly sent me Ryan. Didn't get round to trying it in my  car, and realistically that may never happen.

I wouldn't worry too much. It did exactly what @Wheelie1's did except it deteriorated to a point where the idle was everywhere and I was losing power as well. Plus some starting issues. Oh well, you got some research out of it, I imagine, even if it didn't bring anything back.

Can you not clean it any. I've looked on fleabay & there is about 6 different codes. OK, so you suggest I just unscrew & look at label. Will do that tomorrow thanks.

You'll have to take it out entirely.

 

To take it out:

• Drop lower dash panel for easier access (guides available online)
• Find connector to pedal and unplug.
• Remove bolts holding it in.
• Comes out as one unit, pedal and all.

 

 

 

^ like this, but maybe a bit neater.

 

This was the part number for my pedal. I don't know if yours will be the same though. The part number is up at the top of the unit.

Hi Pentium, Thanks for the pictorial, will be handy. The vag 'Q' numbers are all the same, but, the letter at the end are different?? So it's got to come out!

Happy to have been of help. You're definitely best playing it safe and taking it out to be sure of the number. I just put that number into eBay then sorted the page by price in ascending order and bought the cheapest one. It's still working (touch wood).

It's possible the letter at the end denotes LHD or RHD.

2006 ETKA page relevantly cropped and highlighted. 3rd digit is what differentiates LHD/RHD, various other different characters for petrol/diesel/automatic/manual.

I suspect a 56-plate vRS is going to have the 6Q2721503H variant, penultimate in list of '15' s.

 

Many thanks for that info Pete, and the time you put in finding it. I've actually got EKTA site bookmarked BUT most of the time I can't get my head around it lol.

Haven't dismantled pedal yet (crap weather), but car has not been run for around 9 months up until trip to garage re crank sensor. Lifting pedal back up dropped the revs promptly, so I wondered if it was sticking through lack of use. Last 2 days just sat in the car and constantly up-down on pedal, it does seem as though it's done the trick, tickover now a steady 900, and engine braking as it should. So thanks again, until the next crisis!

My favourite type of fix, a free one!
