Hello all,
as many of you have had this experience I thought I would throw it out to you on your knowledge. I have spent endless hours reading and trawling the never ending threads across a few forums on this topic.
I have not yet checked the EGR valve yet however VCDS said it was on 60 which the in between zone said something like 5-65.
The MAF initially on start up said 480 on the reading which the good zone is something like 180-350. This corrected when I pressed the throttle and went down to 250.
I don't really understand the injection readings but this was:
-0.72 mg/str Injection Quantity Deviation Cyl. 1
0.05 mg/str Injection Quantity Deviation Cyl. 2
0.45 mg/str Injection Quantity Deviation Cyl. 3
0.21 mg/str Injection Quantity Deviation Cyl. 4
Is this a good reading guys?
When the car is low tank it really judders a lot and restarting the engine always resets it. If the car has Redex it doesn't normally have a judder. I have started filling up with Vpower as I drive average of 500-800 miles a week motorway wise. The car previously had the injector unit changed at Docklands Audi however I have no idea what was changed as it didn't state and I bought the car without the service history, this was only found out when I ordered the duplicate service book. I need to test It when It next judders to see if I can see if it is an injector. Also I will check when I'm home from working in Europe to see if there is oil/black in my fuel filter.
What do you guys think?
Many thanks all that reply.
