rado-steve 0 Posted August 6, 2007 Have you plugged in Vag Com and looked what fault codes show??? Quote Share this post Link to post Share on other sites
corrado1.8t 0 Posted August 7, 2007 yes, but the only trouble is its showing codes for things that it cant find due to the transplant but nothing that effects the running Quote Share this post Link to post Share on other sites
rado-steve 0 Posted August 7, 2007 Clear the codes, go for a drive without the problem, plug in Vag com, note down the codes. Clear them again, creat the problem go for a drive then read them again. Should give you an idea of whats the matter! Failing that just disconnect the thermostat :lol: Quote Share this post Link to post Share on other sites
