Hi all, bought a 2008 A5 3.0tdi quattro a few months back and have a intermittent dtc in vcds relating to egr insufficent flow.
No dash lights however and dont believe carbon build up to be an issue as i have checked this and is fairly clean for 88,000 miles on the clock.
Also believe a faulty MAF could cause problems like this so checked advanced measuring blocks at idle:
Actual vale: 13.33g/s
Specified value: 333.1 mg/stroke
Do the above readings sound about right or are similar to anyone else's maf readings?
Thanks for any help
