Hello all,
I have been experiencing a boost related problem with my beetle and wanted to know if anybody else has had the same problem.

My beetle has the sports pack which includes the dash mounted gauges.
Under normal driving conditions I see 2.0-2.1bar of boost pressure at full throttle.

What I have been experiencing regularly is the will sometimes only boost to 1.5 bar of boost under full throttle and there is a noticeable decrease in power when this happens.

After driving for a another 15 or so minutes the boost restores itself to normal and the power is normal again.

No check engine lights come on and the vw dealer can't find anything wrong with it or any bulletins addressing this issue.

If anybody can share their similar experiences it would be greatly appreciated.
