Volkswagen Polo III - Polo cutting out when parking - njs1999
Hello

Wondering if anyone can advise.

Bought a W reg VW polo approx 2 months ago and after a while, it cut out a couple of times when under load, i.e. hard steering.

I had the alternator changed under warranty and all seemed fine until this morning, when i pulled in to a parking space and engine cut out again.

Called RAC out and they ran diag tests on it and couldn't find anything wrong with it. The tested alternator and battery and said they were fine. They were at a loss.

It only seems to happen now when I turn left in to a car parking space, I.e. Slowing to a stop and steering left. Also, the car will take a while to start on the odd occasion.

Thanks in advance

Most likley needs throttle body re adaptation. This requires diagnostic gear but its a very simple process and takes no longer than 5 mins to do . Its worth having the throttle body washed out beforehand and checking that the servo hose at the manifold end hasnt split

Both the above are very common.

Thanks for reply.

My garage reset the throttle body (?). But that has made little difference. I phoned VW and they told me the throttle body was cleaned out in 2005, so perhaps the problem has reared up again

Thanks again and I'll ask mechanic to have a proper look at throttle body, as well as other suggestions.

I would get the garage to check the live data from the engine coolant temp sensor.It may not flag a fault on the diagnostic system ,but its value could be out of range.
