Ok guys, thanks for your input, checked both level sensors and both working correctly, plugged in snap on scanner, no fault codes and all sensors and motors working correclty, so must be an issue with how they are set, so called up local dealer had no clue as per usual, stuck on IOW so what should i do now? manual adjusters for time being will be a good idea safer than not crashing atm!!! any ideas how to do this?
