I have been searching and searching for my first car for months now, finally I chose the A3 1.8T. When I went to look at the car, there was no obvious problems, checked coolant, oil and the whole lot, seemed very tidy and checked out okay with my friend who was a lot more experienced than me...
So... I have had the car a week today, the engine light came on... I took it to get diagnosed and seems a thermostat is faulty for regulating the water to the rad.. anyway... that problem in the process of being fixed, I get home and check the coolant again... there seems to be a yellowy foam forming on top of the coolant which has turned a bit milky... there is no change in the oil though, that all seems to still be fine.
Lets just say it is not the HG, what other problems could cause something like this? Ive got it booked in for a compression test next tuesday but I cant stop thinking of the problem and what it could be... I have been reading up on the forum for hours now and there are so many happy endings when it comes to this issue that im hoping my problem isnt the HG!!!
