Title: trouble turning over when still hot
Post by: mcgee9t2 on 29 May 2012, 21:22

seen this on here before but cant find it.

basically when the cars still warm it sometimes struggles to turn on. and after maybe 10 seconds it will fire up, but will idel at around 1200 rpm for a min or so before droping down to 800.

anyone have any idea.

i remember it being some sensor think it began with p but cant remember

cheers

Had these symptoms on a 1.8T AUM and I ended up replacing the crankshaft position sensor at about 80,000 miles. Best to plug in a fault coder reader to confirm where the problem is as a sensor from the dealers is about £100. Cheers.
