Faulty DV?

[grumbas]

My S3 is suffering awful turbo lag and generally seems a bit down on power.

I've seen somewhere it could be the DV and the way to test it is to remove it, push the mechanism up and put your thumb over the small pipe connector at the top. If it comes straight back down its had it, if it doesnt release until you move your thumb its fine - have I got this right?

Assuming fine is knackered, is it better to just get another Bosch one from Audi or go for something like a Forge one? The car is running a bit more boost than normal so I'm leaning towards Forge or similar!

other candidates if its a 1.8T are the MAF or the coil packs.

To check with it is your dv take of the airbox and blip the throttle or drive it for a little way, if it chirps rather than whooshs your DV isnt working properly

Unplug your airmass meter and try it like that.
