I have yet another problem with my skoda VRS

well a couple of problems

1. When you go backwards in the car it makes a terrible noise like grinding but i high pitch sound its terrible any idea?

2 . when my skodas idle now and again loads of black smoke piles out the back... but it drives absolutly fine :S

Thanks:)

Noise is back brakes, they all do it and its really annoying, can try cleaning back pads up in carriers and it stops for a while

Black smoke out of exhaust sounds like its over fueling quiet badly, is maf sensor faulty or does it have a boost leak

Any possible way to test maf? disconect it? thanks

Yup if it runs better with the MAF disconnected then its at fault

Thanks i will have a try today:)
