Hey all,

I have a 2003 VW Jetta IMMO3 with a Kline short in the cluster. I have a Ross Tech Hex USB+CAN cable, a Vag Tacho 2.5 cable and a Vag K+CAN Commander 1.4 cable. I also have the software for each cable. The car does run with the bad cluster in it, but I am unable to access anything via the DLC. I picked up a used cluster from another 2003 Jetta 4 today and would like to adapt it to the vehicle. I have the PIN from the cluster I got today, but I am unable to retrieve the PIN from the damaged cluster. I hooked up the replacement cluster today and was able to access all of the available control modules. I am assuming that I should be able to download the ECU EEPROM, with the replacement cluster in place.

Using one of the cables I currently have, would I be able to download the EEPROM data from the ECU and extract the PIN from that? I did download the latest version of nefmoto, if that might help me.

If anyone knows what I could try, please let me know.

Thanks!

I was unable to download the ECU and I believe the PIN I was looking for is 3585. I'm not sure though, since I was unable to adapt the new cluster to the car. I followed RT's instructions to the letter and the donor vehicle's VIN keeps popping up in the cluster.. Any ideas?

Ok... I really feel stupid now... When I went back and looked, I had read the wrong digits in the bin.. SHouldn't the ECU PIN be 5390?

Also, I didn't check my battery voltage.. Sitting in the car, ignition on, engine off, for three hours.... Makes the battery voltage kinda low... It was at 10.06VDC.. It's a new battery too... Go figure...

You should have your car on a battery charger when you're doing flash operations.  Losing voltage in the middle of an operation is a good way to brick an ECU...
