Hi everyone sorry I haven't been on for a while.
I've now got a audi a4 2.5 tdi v6 diesel had to do water pump and timing belt idler after the failed. Got it all back together but it had a tappet knock ( rocker came off ).
Got it all back together but it now sounds like the fuel pump is tapping now.
Anybody local to me know anything about bosch fuel pumps? Or audi diesels.
