The glow plug light started blinking one day, so I read error codes and found "01044 control module incorrectly coded" in 01-engine module. The software coding field is 00000 so I tried coding it to 00002 as the car has a manual gearbox and no abs nor air conditioning. At first this seemed to be working. The error code can be erased and doesn't come back. But as soon as I fire the car up and take it for a drive the warning light and error code are back. I did an auto scan and the results are below. After that scan an additional code was raised in engine module that cannot be erased: 65535 Internal control module memory error.

Do you think my ECM is simply toast?

Code:
Chassis Type: 6K - Seat Ibiza/Cordoba (1993 > 2001)
Scan: 01 02 03 08 15 17 25 45 56
