Hi all First post so apologise if this has been covered but couldnt find anything when searching. Would appreciate some advice. I have wanted an A3 for years, and due to the family Vauxhall Signum beginning to look like a money pit, decided it's time to look for a new car. I have been to look at 2006 A3 2.0 170 sport. Has under 50,000 on the clock, full Audi dealer service history, last major service in September just passed, and had cambelt and water pump changed in the last year. This is longer than the 5 years stated by Audi, but is that an issue as it has done under 50,000 so far? The car looks pretty tidy, started first time from cold, seemed ok mechanically, BUT I noticed the following Oil is jet black, didn't seem lumpy, but jet black After taking off the oil cap, there are a few clear "droplets" on the underside of the cap and a light brown ring around the edge of the cap and on the rocker cover (if that's the correct term). Finally, the water fluid levels are WAY above the maximum line in the water tank. I don't know a great deal about cars, but I am wondering if this a potential head gasket problem, or the gasket on its way out? I have read that gaskets really go on these cars, so is it perhaps something else that is wrong, or is the residue probably just the result of the car sitting without being started for a few days (the dealer stated that he has had it for around 2 weeks). Would the high fluid levels indicate that the dealer is trying to hide something (poorly). This is being purchased as a family car, and I intend to take good care of whatever I purchase, but don't want to buy something that I will end up ploughing money into again. There is no dealer warranty and The car is quite far away so getting my mechanic to go look at it will be difficult. I was thinking of paying for an AA vehicle inspection, but the earliest they could book would be the 27th, and I have a feeling that if this car is in good condition, someone will snap it up by then. Any advice would be much appreciated, thanks in advance and sorry for the long post.
