Golf MkIV Fuel starvation/throttle issue - simonc1978
Car: 2001 Golf MkIV, 72,000miles, petrol, 1.6

I first had this problem in Feb 2006. As I was pulling into a car park the engine cut out on me at low revs. Couldn't get it started normally. Got the AA out and the guy reckoned it was a throttle potentiometer problem. He started the car by manually opening the fuel valve. Took it into VW and all they did was reset the ECU.

Everything ran fine until last Friday when the engine cut out again. This was as I was changing down from 3rd to 2nd. Couldn't get it started and it was towed back to my house. I got to recovered to a VW garage but before I did that I did manage to get it started. It was very "lumpy" though and it soon cut out with the Emissions Workshop message coming up. Yesterday, VW cleaned the throttle housing and roadtested it, claiming it was all OK...

No more than half a mile down the road from the VW garage and it breaks down again - with the same problem!

What could be the root cause of this? Is it in need of a new potentiometer?

I have noticed a slight rattle when I've been slowing down recently. Could that be part of the problem?

Also, can someone recommend an independent VW garage in the Stratford/Warwick/Leamington area?

Thanks for any help.
