A8 3.3 TDI

Hello.
I bought an A8 3.3 TDI, because my 2.8 was crushed just before Christmas. I bought the car with a defective pipe from the dumpster to the AGR valve and thought about it then, When I then looked in the rep guide stood as the first set Build engine with gear. I had missed that, but I wanted to try it without the support and it worked. I was the first to expand both gear bearings
and the engine then lowered so that you can easily extend the two air mass meters which was not very easy, then I removed the line from Turbo to LLK (in the suction bridge) and the vacuum pump (in order to get the vacuum pump out the KW lines to the heat exchanger). Now it was easy to dismantle the pipe.
I hope this description is written helpfully if someone else has to change the tube.
