I need some more help with a dodgy specialist install. About 4 weeks I took my car to the specialist for squeaky suspension and noisy exhaust.
He told me my rear bushes were worn, fine.
He told me the 3rd party exhaust I had wasn't designed to fit the footprint of an a3 and he would advise I change it for a standard audi exhaust as it would fail an MOT.
I agreed and had the work done. When I got it back the brakes didn't work properly - I took it back.
Now the exhaust sleeve keeps coming loose - I've had it tightened twice in about 3 weeks.
Before I phone them up and whinge at them again is this a common problem with a3 exhaust sleeves or is this a dodgy sleeve job?

ta,
