I think it's possible to disable this. However, are you sure that is the problem? This could also be a failing MAF sensor, a sticking VNT turbo mechanism, or dodgy N75 valve (or vacuum hose/wiring for the N75). The N75 controls the VNT machanism. Take a look at http://www.tdiclub.com and ask in the forums, and have a look at http://www.technologie-entwicklung.d...t15-turbo.html |
