: A8 4.0TDi Stretched timing chain problems!

My 2003 A8 4.0 TDi Sport was diagnosed by an Audi main dealer with a stretched timing chain one one bank of the V8 (this was evident from the two cams being out of sync on the right bank looking from the front of the car). My local (non franchise) garage replaced all of the chains (I saw the old chains in situ with the engine out of the car and sure enough one was stretched) and took the head off to ensure that none of the valves had hit the block, which they hadn't. However, they cannot get the engine to run on any more than 4 cylinders now and they have no idea what to do next! Has anyone else had this experience?
