Been having problems with my 2.0T running poorly (no cel) for about a month now and the only error it was throwing out was the DV but I held of changing this as I had already changed this 18 months ago to the revised OEM "D" valve when the car was remapped due to the common failures of the rubber memebranes on the originals so I doubted this was the problem. Any way I changed it back to the orginal DV and it was right as rain the revised "D" dv just fell apart when I finally removed it. This fix only lasted a week however as it has now blown the rubber membrane to bits on this DV and I have no boost atall just waiting for another "D"to be delivered and hopefully all will be well again but if this one fails I need to look at possibly replacing with the forge dv but thats £150 and install doenst look staright forward ! God knows what the boost pressure must be to destory all thes diverter valves !?!
