to cut a really long and protracted story very short been having major probs with S3 overheating & losing coolant (related I'm sure)
Audi/insurance Company ruled out head gasket failure suggested dodgy water pump and temp sensor
Mackenzies replaced water pump as a warranty item (it was only fitted 10k ago)
problem remained and is now really bad. I mean it'll last about 2 hours sometime without needing a couple of litres of coolant.
There is no evidence of coolant loss at any level at all (i have searched the drive so many times in the ams to find some, figuring it must be coming from somewhere.
I do have white smoke (sometime s quite thick) and a slightly rough idle.
I read somewhere else that the rough idle could be caused by temp sensor faults? why's that?
When i opened her up yesterday as it just reached 100 degs the fans were not even cutting in.
Is this controlled by the same temp sensor.
If so thinking of swapping it myself and then going on from there.....
the saga continues...please help.
PS What's the part code for the temp sensor - anyone know - is it ieasy to fit...
