Having intermittant boost from my AGU A3, also the other problem is that it seems to be running out of steam at at 100mph (on private roads)
Not sure if this is a boost leak issue or I'm in need of a new N75?? I havent got access to anyone with VAGCOM so havent scanned the car. I know that there is a service with Rtech for £65 that do a rolling road and a smoke test on your car etc. Do you think it may be worth doing that?
