Hello, just picked up a 1998 A4 Avant 2.5 v6 tdi. It has a coolant leak which ive found to be the metal pipe that runs through the valley of the engine, splits off to go to the heater matrix and to the bottom pipe of the expansion hose. Its rusted through where it meets the engine just under the fuel pump. Part number of the pipe is 059121075K. Does anyone know the best way to change these? Already got the EGR out the road at the downpipe. Any help would be much appreciated!

Cheers

Murray

Did it look like this and did you fix it?   Parts 1 & 6.
