Having decided to get rid of the A160 , I thought I would try to cure the "F"ing display fault . Removed handbrake console, took the pcb out of the PRND unit and sprayed it with electrical contact cleaner . Made sure it was totally dry , reassembled the unit and started up. Dash indicated P, moved gear lever to R , dash still displayed P and car did not move, moved lever to N , dash still displayed P , moved to D , dash displayed R , but the car was actually in drive! a slight predicament as it is at the bottom of the drive , facing the garage!. I really do not want to throw good money after bad by buying new pcb`s etc , and still have a faulty car. I bought my wife a 60 plate Kia Soul yesterday ( sadistic I know! ) , thinking I would give the A class to my youngest son , but it seems not such a good idea since he always wants me to sort any problems with his cars!
