hi got 02 td4 whe free wheeling down my drive and turning the steering wheel i can hear a scraping noise sounds like brakes rubbin i think its coming from the rear butnot sure did jack it up and spun the the wheel but no noise seems to be only when free wheeling.also when coming to a stop the rev counter seem to stop at 900 i think then drops to850 is there a reason for this but drops once car as stopped if that makes sense thanks
