Hello,

I have recently had my car in the garage to change Dual mass and clutch. Whilst it was there my turbo seals where leaking slightly, so I got the turbo reconditioned.

Before the car went into the garage I had already noticed some lack of power.

I have had my EGR removed and car remapped to 179bhp. Much before this issue happened.

Since receiving my car back, there is now no power (boost), feels like it is in limp mode, as I cannot hear the turbo spool up etc.

I have checked the N75 and looks to be fine, checked for vacuum leaks etc but cannot find anything.

There are no Diagnostic codes, Could the crankcase breather be blocked? Turbo actuator not set-up correctly?

Below is VAG-COM Log: Please let me know what this could be?

What was the garage's opinion of lack of power?
While I am not familiar with the read out,I do seem to remember reading that a m.a.f. reading only up to 400/500 max.could be faulty.
I had one with low reading and swapped it, and got power back. Hopefully someone can confirm if this may be correct information.

The garage's opinion was possible the crankcase breather was blocked.

I have now changed the Mass Air Flow Sensor, & finally POWER IS BACK.

Thank you very much for your help. You can now close this thread.
