Looking for some advice on this mystery. About a year ago I started having issues with the drive block system. My local Porsche dealer determined I needed to send out the 3 boxes under the passenger seat and the keys to be rebuilt. I sent everything to Specialized ECU Repair, they rebuild/fixed everything/ and tested it and sent it back. Once I drove the car 20-30 miles I got a check engine light. We cleared the light and 20-30 miles later it came on again. We once again removed the 3 boxes, sent them back to Specialized ECU where they reworked the boxes again. I then received them back and reinstalled to once again have a check engine light after 20-30 miles or a few starts. The car has no signs of having any issues, it runs perfectly, I just still have this check engine light on. When we scanned again we received the same code, Fault 103 E Prom faulty. Does anybody have any tips or advice on how to remedy? I hate to take the boxes out for a 3rd time only to end up in the same place, especially since it usually takes weeks to get the electronics back.

Try a different place? Maybe Steve Weiner or Loren?
