Title: Trouble flashing 4Z7907551L Allroad ecu. Post by: stuklr on September 18, 2013, 07:27:18 PM I have am trying to bench flash an 01 allroad manual ecu. I am using the same bench harness I have used dozens of times before, but with this one I am getting the immobolizer is not authenticated message. I have voltage supplied to pin 21. Does it need the resistor? I thought it just needed power to that pin. Thanks all

My galleto clone works like 10-15% while mpps works everytime. Who knows LOL |
