Car is B6 S4 and just had intermediate timing service done.
Looking for a little instruction on how to do data logging with VCDS/what blocks I need to measure.
I don’t have the exact codes right in front of me (at work) but I have been having some issues with occasional rough idle as well as a pulsing kind of feeling when cruising (Which has begun to happen more frequently). Finally got a CEL and I got codes for BOTH banks rich and some code for the MAF. I have Vag Com, but I have never really used it beyond pulling/clearing codes, so I am looking for some instruction on how to log the maf readings to see if that is the issue.
Also would like to note that I have what I believe to be a clogged carbon canister (due to overfilling my tank ::)), causing my tank to be a PITA to fill, no idea if this could have an effect on my MAF/ fuel trims.
Will post up the codes when I get home in a few hours. Thanks in advance.
