Evening people, has any one had any thing like this happen or know what to do next? my a4 170 b7. 3 days ago emmision light came on and had the erg( valve on the manifold that recycles exhaust) replace and reset . All was ok until today after very short journey glow plug light came on while driving. Got home turned off then read to check brake light which were ok but no light now but it does not have the kick when u get to about 1900 rpm but does kick at about 3000 other thing to add is I was trying out the speed warning thing and think that may have come on just before glow plug light did.Any thing to check as have a journey to Portugal in a week. Thanks Also just wondering if resting the ecu would be a idea or would this just hinder me when i go back to the garage on monday as they will want to plug it in and would not want to clear any fault codes that would come up.
