Had it towed to an indy shop and they replaced the immobilizer and DME with a used unit from Ebay. It was still not running correctly.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Anyone know what would happen if you put the wrong part number DME in the car? I am HOPING it just would not start I have the correct DME part number if we need a correct replacement. Some indy shops have zero idea what they are doing.

POST 2Original post

What is the PN of the DME you are trying to use, and what is the year and model of the 996?

POST 3 / ORIGINAL POSTEROriginal post

The PN of what I was told needs to go in the 2002 996 Cab is 99661860400 (this was from Porsche) His indy put one in and it is not running right and the indy can't seem to program it right. He has obviously had it with this goof ball. It is probably going to need to go to the dealer. We are trying to work that out now. If it did not start with the wrong part number that would tell us that at least it has the right one just the wrong programming.

POST 4Original post

Not only do you need the right PN, but it needs to be coded for your car with PST2 or PIWIS...otherwise no go.

POST 5 / ORIGINAL POSTEROriginal post

No go as in no fire etc? At least it fires and runs but not correctly.

POST 6Original post

it should do nothing if it is the wrong DME or wrong code. If it is running, you have other issues...post the codes and we can help diagnose.

POST 7 / ORIGINAL POSTEROriginal post

SWEEET! That means it is solvable without a new DME. It is going in Monday time frame for diagnosis and repair (on his dime)

POST 9 / ORIGINAL POSTEROriginal post

From what I have found here there is not. As the car starts and runs. Needless to say it is going to Porsche for further diags. The gentleman selling the car is in the Navy and when he came home it would not fire. Just crank. Had it towed to an indy shop and they replaced the immobilizer and DME with a used unit from Ebay. It was still not running correctly. The indy had no idea how to fix. I want it checked out by Porsche as part of the PPI. He will fix what is wrong but we were trying to trouble shoot if the indy just put in the wrong ECU or what. Heck it could be a bad MAF. But Porsche will figure it out.
