Hi ive recently posted a thread in the 'b6' section relating to a few problems i was having with my 2004 a4 tdi. Im kind of new to this forum and still working my way around
I disconnected and plugged the egr valve today, drove about 15 miles down the M5 and all of a sudden the engine management light came on.
Whilst the egr was disconnected it stopped smoking and mis-firing which temporarily sorted the problem but now the engine light is on. Have'nt had a chance to plug in for fault codes yet but can anyone shed some light as to why this has happened? thank you in advance
