2012 Volkswagen Passat SE 3.6L (CDVB) 6-spd (09G) — 1VWBM7A36CC033356
No Crank/ No Start

Good morning, 

we have a VW with a bad ECU. The car would not crank, the aux. fan ran at high speed with KOEO. We checked power, ground and communication to ECU and determined that the ECU had failed. We initially purchased an ECU with the security deleted and were able to start the car. However, there were multiple fault codes because of the tampering with the security and we decided to send out the original ECU for repair. We were told the ECU is damaged beyond repair. Our question is whether anyone knows a company that can virginalize a used ECU for this car that we can program and code later or our only option is a new ECU from the dealer. Thank you for your time. Have a great weekend.

Send us the original and we can clone the original onto another unit. That would make it a direct swap …
