003, 118, 115,020, 031, and 032 are a good starting point.

Do no more than 2 at a time to get any reasonable samples.
003 and 020, then 115 and 031, then 118 and 032.
This gives you, airflow, actual timing, timing pull, requested boost, actual boost, target air fuel, actual airfuel, n75 duty, inlet temp, actual boost, and then finally fuel trims.

MAF readings looking a bit low , with CFs a bit high.

cheers Dave,but for a car thickie,what does that mean mate

is the maf on its way out? and what are CF's and what controls them,sorry for my ignorance

I'd like to see more logs (as quoted) before passing judgement. CFs (correction factors) mean the ecu is pulling back timing because things are getting a little hot in the combustion chambers - poss running lean because the maf is on its way out and is reading less air than is actually flowing.

ok Dave,thanks for the info mate,will get some more logs done tmrw night.BTw Dave,i am having oil issues right now http://www.seatcupra.net/forums/showthread.php?t=235635 could there be a connection anywhere at all?

Hey. I am talking about Vag-Com yeah.

I am in Carlisle, but often work all over the county.

Whereabouts are you?

I am picking my LC up today, all going well. So just scouring the net looking for decent garages/workshops for servicing, etc.

Help appreciated on that front!
