just picked up a 52 plate A2, 1.6 FSI (BAD engine code) 91k miles full audi/specialist history not running, the previous owner said he came out to it one morning and the coolant light was on, so he topped it up, ended up needing a lot of coolant, tried to start it, nothing, not even starter spinning called the AA, they diagnosed a head gasket, towed to the garage, and not touched since just removed the head, bores are full of oil/water mix, crank case full of the very same head looks like new (havent pressure tested it yet), surface of the block look fine, bores all good head gasket hasnt really given any clue to if its failed question is, where is this huge volume of water likely to have come from? oil cooler? cracked head? cracked block? head gasket? are the fsi engine known for any likely faults?
