Hello everyone,

This is my first post on this forum, I have looked elsewhere for an answer but I couldn't find anything that specifically related to what my problem is.

Having had the glow plug light flashing and the DPF Light come up on my A4 B8 2.0TDi, the Emission Control Light has now come on (and stayed on, solid) even after the Re-Gen has been completed. Having worked for Vauxhall for many years I am more than familiar with DPF Issues, but I have not had the ECS Light appear before. Engine doesn't sound any different under load or on tickover and the performance has improved since before the Re-Gen.

The only reason I can think of as to why the light has come on is due to the fuel being run down quite low in the tank (10 mike range showing) and dragging through some crap (technical term escapes me) from the bottom of the tank and is now clogging up a sensor.

Does anyone have any advice for a relative mechanical novice?

Thanks in advance!
