Hi. I have a similar problem and cannot find out what it is. If the car has not been driven in a few hours the sound is extremely worse. For instance, on start up its ok , but once i start moving "but only when i turn right" i get this massive screeching sound. its sounds like its coming from the right front. The sound seems to detioriate as time passed but its there again the next morning> Does anyone have any answers to what this could be please???
Also, i had the car mapped 40,000 miles ago. Its a mk5 gti 07", only recently there has been a sudden loss in power. If i had to guess a figure its seems to be running around the 140-150bhp barrier but sometimes the turbo is completely gone and there is no power at all. I had the boost sensors replaced but this didnt fix anything. Any Ideas on what it could be?
