Car seems to behave normally, pulls hard and no unusual noises.

I though it felt a bit slow yesterday, but this fault is like couple days back, after I removed my APR stage 2 pipe and cleaned it and also installed the NSP boost hose tap.

I double checked the stage 2 pipe to turbo coupler and fit it more properly. The tap NSP hose seems flawless.

I have the rev D piston type, these can break?

Note that the car is boosting normally…it's peaking to 26psi, holding 24psi and then around 18psi at redline, this is with the "beta" APR K04 file, it's been always like this..

Shall I be concerned? or can faults just happen like that and not come back?

I am experiencing the same, did this ever get resolved?

000665 boost pressure regulation p0299 control range not reached

I am APR Stage 1.

Just replaced the DV with the latest version, CEL popped up again. Car runs great, just like it always has. Seems to happen when the A/C is on and I am accelerating at low RPM with a high load.

Any other solutions or suggestions?

Log your specified vs actual boost using vagcom and the n75 duty cycle.

Check for boost leaks. If all is fine, it's probably your turbo.
