i have a 2.0ltr diesel audi a3 on a 05.when i give it some beans hot or cold mty turbo cuts out and my engine management light comes on...... But this is intermittent. When i have took it to my local man he has put it on Vagcom and the fault that comes up is Boost pressure.... Its been smoke tested and no leaks were found...... When i asked him what the problem was a bit vague about what it was but said it could be the start of a knackered turbo bearing...... He told me to keep driving it till it got worse...... Does anyone have any ideas what this problem could be because its driving me mad...... Cheers Mike
