Test drove this car yesterday: http://pistonheads.com/sales/1314463.htm When I had a look at the oil filler cap it was covered in emulsified oil which says to me head gasket failure. Have been reading a few posts on here however that suggest condensation can build up in the cylinder head if constantly doing short journeys?? The emulsification was also on the dipstick aswell so water must also be in the sump!! This rang alarm bells for me. Is this common on the S3 or am I right to think something's wrong? Unexpectantly for the milage and age, the car was actually abit of a dog. Tatty interior, scuffs and scrapes across the front bumper and the underside was very rusty. Tried launching the car at 4k revs with esp on to test the haldex and revs climbed to 6k+ very quickly without actually really going anywhere, combined with a strong smell of burning clutch!
