Hi I took my secenic II 04 diesel to a roll on carwash today and as I parked for the hoover everything went mad. Automatic Parking Brake stayed on, all the dash lights are on, check air bag, low oil pressure, service, Triangle P , check parking brake. All these come on repeatedly. Also cant use indicators or turn off lights or wipers or engine. Had to stall it to stop it. HELP ME PLEASE!!!!!!!
