Folks, hope you can help...
I've got some really dodgy idling problems at the moment which is getting on my nerves more than a bit.
Basically the idle is really really lumpy, and fluctuates between 800k and 1100k.
When running warm, the idle will suddenly start creeping up, stop being lumpy, but keep going till it reaches about 2.3k, then drop back to 800k and lumpy.
A mate of mine has Vag-com and the error codes are listed as below.
We also looked at the ignition timing via Vag-com, and it's steady when driving, but on idle it's all over the shop.
I'm guessing the first thing is to swap out the temp sensor on the rad (does anyone have the part number for this?) and see what happens, as I've heard that small sensors on these cars can throw everything outa whack.
Any other input though would be appreciated!
