sorry to hijack but i have the same sort of
problem, but also when i start the car first thing i get less than standard boost. If i restart the engine boost comes back? Had a few members look at it on Sunday and done a check with vag-com. No errors showing up but didn't have enough time to do logs.
Again its a of the beaten track re-maper but is known for good service and good maps. hes going to look at the map file but as i am in Glasgow and he is in Yorkshire its a bit far to drive in case its not the map.
I have changed the tip / dv and intercooler to intake pipe all with forge parts. i now dont want to fork out more money until i know what i should be replacing. Can anyone advise on module number to log in vag-com for the FR?
