My 2001 Audi TT went in to resolve several vacuum leaks. I was told EVERY vac line was getting replaced along with intake gasket. All they did was replace the brake booster hose, nothing else. My timing belt slipped a few month later, I removed the cylinder head to find all the cruddy original cracked vac lines that they did NOT replace, the intake gasket was not replaced. (Timing belt slip was not their fault, this is just how I discovered they did not do what I was charged for). I only took it to them because I did not have the time to fix myself...should not have trusted them.
