Need any help or advice on boost problem

[RabReith89]

Hi i have been having a boost problem for about a month now, where my car is not boostin at all it drives like its a 1800cc??

Befor it got to this stage it was just boosting on and off, now the TCS light stays on aswell as the EML.

The car was been maped by c-codes about a week befor this started, am sure the map is not the issue.

I have been reading alot about this type of problem and most cases its the n75valve or the maf sensor.

Parts i have replaced so far: 4x coils, 4x spark plugs, new n75valve F, New maf sensor, cheeked all hoses ect

Had my car vag-comed to day and this is the fault codes thats coming up guys.

Yes that is what all the short to grounds are, and why it is always in limp mode.

I was more specific tho silencer...

Mine blew it all the time, had it in the garage and everything before someone on here told me the same.
I now carry a spare fuse in the ashtray.
