I have 2007 TT 2.0 petrol which Ive owned from new and not had any issues with (unless you count the gas strut on the boot giving way and the boot lid crashing down and almost killing me as I was retrieving my shopping, anyway, minor glitch....) Its on long-life service intervals and has only done 26k from new, just had it serviced at an "Audi specialist" garage in May and have since done just under 2,500 miles and the oil light has just come on. Never happened before, I dont drive it particularly hard, it does about 28 miles a day commuting to work! There's either something wrong with the car or the garage! Just wanted to hear of anyone's experiences before I phone the garage and have a possibley unnecessary strop!! many thanks and be gentle with me, Im new to this!
