The tech says he can't communicate with the DME. The 9110 code in the cluster indicates a dead DME.

So what are the options?

I understand I'll need to either code a new immobilizer module to a new DME, or get a paired set.

Can I widen my search to a comparable 996 DME since I'm using the 74mm TB?

Or can I just use any DME 99661860500?

Thanks.

DTC 9110 indicates the DME is not communicating, could be the DME, but as you have been switching harnesses around, I'd start by checking to make sure the harness is good (no breaks or shorts, lose connections, etc.) before swapping out the DME.

He did check the harness and found nothing. Also checked for ground to cluster and DME.

 

Update: now booked with a Colorado Porsche specialist shop in the coming weeks.
