codes can be erased without the stop start procedure as suggested in vida . what that dose is allow the modules to re set from a set point ie powered down which happens when you restart the car anyway . there are some good vids on youtube by Mathew leavsley and farpoint farms there are others but i cant remember them. its possible that by running the car whilst parked at an unusual level you may have let air into the fuel system. fortunately the d5 v70 will self prime if there is enough fuel present to cover the pick up point.
