Hi: Pretty worried about my 2008 328i Sport Wagon. Turns over but doesn't start. Dealer printed out OBD codes: 2A43 DME: Valvetronic, Thermal overload protection warning threshold 2A41 DME: Valvetronic, elecrical overload protection 2A38 DME: Valvetronic, servomotor: sluggish movement or open circuit 5E19 DSC: Engine management: interface A559 Instrument cluster: Power supply has been switched off ( closed circuit current... They changed out the Valvetronic servomotor but problem persisted. How do I reach one of the TSA's for help? Thanks, Scott
