If a car enters limp mode will the requested boost (block 115) drop?

Might be a silly question but hooked vag-com up to to a 1.8t Ibiza and it drove like it was in limp mode, requested boost seemed normal but actual boost was way off ?

Yes it would if it was actually in limp mode. Any fault codes? N75 valve working ok?

Have not checked N75 as yet, assume this is via output test in VCDS??? Faults as below also MAF reading 0g/m when logging block 002;

Good bet that's a faulty fuel pump relay. It's a 40 amp beast and supplies all the listed components.

Agreed.

Thanks guys will look in to it

Crickey that's a nice list!

As the two gents above have said, checking the fuel pump relay would be a good start. Look for a black relay with "109" written on it in white, in the relay panel

under the dash.

thanks for all the help turned out to be a blown fuse after testing them all.

Why is it always one the last fuses ???
