Okay, my car had been sat stationary for 3 weeks, got in it to drive, the car wouldn't rev past 3000rpm, its feels like its trying to kill the car like a limiter. If i hold my foot to the floor, the epc light will come on, it will then rev right round, but it is in limp mode and no boost. Ive changed the diverter valve as was told it could of been that but still doing it. Nothing it coming up on VAGCOM either. Any help will be much appreciated. Cheers!
