Trouble?

[steamship]

Jim, rather than go O/T on the 'MoT Time Today' thread, can you confirm which sensor you got replaced? Was it the throttle position sensor or the pedal position sensor? If it's the PPS, I might consider trying a second hand one from our forum sponsors.

Oh, sorry Sean, I missed this question. I was told it was the throttle position sensor, but I'm not certain. The receipt just says 'sender module', but I'll give them a call to find out and get back to you.

It's well worth a mention that the whole car is transformed as a result though.

Ever since I bought the car, the fisrt gear change up in a morning was a bit clunky (even after the gearbox services) and occasional other changes were clunky too. Nothing major, but noticeable.

And I always thought there was a hint of a misfire when I put my foot down at already high motorway speeds. But I never saw a misfire report on VagCom and the eventual removal and replacement of the stuck plug did nothing to improve it.

But now, the gearbox is as smooth as silk and the general response of the car in all types of driving is transformed. And there's not a sign of the 'misfire'.

It's made a heck of a difference!

So, apart from the very obvious intermittent fault with the dash lighting up and the power control coming on, I suspect that these things wear gradually before they fail. It was an expensive part, but I'd spend the money again happily (but I wouldn't risk a second hand one).

I'm equally interested......

I phoned the garage this morning and am awaiting a return call. I'll post as soon as I hear back.

It was the throttle pedal sensor module, part number 02 890 747 5BD (although that looks a strange number to me). And the part was £325! But worth it IMHO.

Thanks, I guess we now have to see who takes the plunge first and follows your lead.
Any idea how difficult this is, i.e. DIY or not and how many hours a garage would charge?

This link gives alternate Bosch part numbers such as 0280752022: https://eurochopshop.com/shop/a8-s8-...0-00-01-02-03/

I don't know how difficult the job is. Mine was done at the same time as the cam belt for a total of £164 + VAT for labour
