Hi,

First post, so please bare with me!

I was travelling home on Friday, some 150 mile journey and all motorway. About 50 miles in, travelling approximately 75mph, the car started to cough and splutter. The juddering and jerking got progressively worst until after another 10 miles down the road the car stalled with and engine management light one. I let my foot off the accelerator and reapplied, the car fired back in again. A little scarey in the fast lane over taking some lorries!

I got the car home by accereating / letting off, as it wouldn't take 10% throttle,.. so cuising speed. Weird! People following me must have thought I was a loonatic!

My mate stuck it on his diagnostics tool (not sure which one he uses), and it flashed out the Thottle position sensor, the only error code. He replaced the pedal, which I believe has the tps. All good over the weekend, but I didn't try the motorway..... until today! Same again, cutting out at 10% throttle, although again,.. it didn't start doing it until about 40/50 miles in. And again it was a progressive thing.

Anyone got any ideas?

What is your engine code? It is on the white sticker in the spare wheel bay.

The throttle position sensor is on the throttle body. Depending on your engine I think it may need a whole new throttle body.

Sounds like water in the plugs under the ECU, a common problem which gives the fault code you mention, I am just doing one at the moment.

I've had a look at the sticker in the spare wheel bay,... many, many codes...

Thanks Crasher - sounds a simple one. I'll get my mate to take a look at that one. Where is the ECU by the way?

It is an AWX TDI engine. The ECU is in the box under the bonnet on the drivers side.
