DV Fitting
Top Cat:
I would be surprised if it never, 99% of boost problems are down to the diaphragm type DV, you could also give all you pipe work a check to the cooler as they can come loose or perish a bit which will give you boost drop off. :happy2:
vRS Carl:
As TC says its a straight forward job.
You will need the following tools though before you start
T20 & T27 torx bit for the engine undertray
5mm or 6mm hex Allen key or bit for the DV which is held in by 3 bolts (beware there isn't much room for a socket set and you will need an angled one to do it properly) I find a long Allen key the easiest way. The reason I say 5 or 6mm is I have come across both size bolts holding the DV in but the default is 5mm iirc
It will take you about 45 mins to do yourself.
