If I was going to order a new DV from VW, would i get a diaphram type one or the piston type one that was originally for the TSI engine?
Also on the TSI engine, is the piston type DV turbo mounted like on the TFSI K03 cars?
The reason I ask is that ive been running a revision 'D' piston type DV for over a year now but on a K03 turbo. Now that Ive had a K04 conversion done and the DV relocated, ive noticed that my piston type DV is sometimes slow to respond and also doesnt like the pick up after a fast, maximum boost/revs gear change. Basically it feels like it is sticking like my old forge DV did if i was a little too late on servicing it. If I put my old diapham type DV back on (revision B), the car/boost/pickup is spot on.
I was wondering if the heat from the K03 turbo could of damaged the piston type DV if it was never designed to be turbo mounted
