so the gf ordered her new audi A1 back in 2012, since feb this year it has been taken to audi garages 4 times. Ive read on here that other people are also having engine problems with their A1. what happens with her car is when in the morning heading to work, she starts the car and its very hard to idle. it literally sounds like a tractor. when she takes off, its slow and sluggish. she took it to audi the first time as the was not convinced that it was doing to proper milage that it should do to a full tank. the replaces the injects but and this sorted that problem but only for about a day as she notices the next morning that there was diesel spilage where she had parked - turned out the fuel pipe clip things had not been connected properly. the replaced a load of parts the last time it had been up and now its back up the road to them for the fifth time!! she is really getting annoyed about the whole thing and would love to just had in the keys and demand her money back. 18k quid for a car that wont drive... she has no HP on the car either. broadly speaking, can she .... just hand it back? refuse to pick it up and demand a new car to the value its worth at the moment? he warranty runs out in 10 months time and she fears that once the warranty has expired that she'll have the same problems but with a large bill at the end of it each time something goes pear shaped?
