I've got a problem.

Ran to Gatwick and back this week - 600 miles in total.

Half way down I seemed to lose boost. Then all of a sudden, I would get (some) boost again. Turbo seemed to pick up if you revved it higher.

It's really tempromental. One minute I (think I) have it, then the next it feels like I haven't.

Does anyone know off the top of their heads (before I start ripping things to bits) what could be causing this?

N75 valve maybe? Loose vaccuum hose?

Any suggestions welcome!

I had an intermittant N75 fault that turned out to be a broken cable, could be something like that?

Given the BBQ i would be tempted to look at N75 connection.

Have you got VAGcom?

Mark - no VAGcom I'm afraid.

Will look for loose N75 connections tomorrow. Will swap MAF over as well to see if that makes any difference.

Cheers chaps.
