I have been restoring a 2005 Boxster that suffered water ingress to the cabin. Most of the roof and rear module stuff is now fixed.

However, there were a few persistent convertible top DMLs in the Gateway module that I was trying to clear with my PIWIS II tool. I think I managed to erase the programming of the Gateway instead of the fault codes.

Now the instrument cluster is dead, the spoiler is always extended and the cooling fans are running at full speed whenever the ignition is on.

I tried to reprogram the Gateway using either the Automatic or Manual programming modes, but both give the following error:

No relevant programming rules found. Cause: Part Number of GATEWAY control module is not available in programming rules.


Does anyone know how to fix this?
