Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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

So why is it i can buy the immobilizer bypass for $675.00 for a 99, but can't for a 2000 ? What's the difference between the two cars?

POST 2Original post

Probably a good question for ECUDoctors - http://www.ecudoctors.com/ I believe it is a difference in the ECU/DME programming. One can program the 98/99 ECU/DME to ignore the required input from the immobilizer, but that was changed in the ECU/DME 2000 and beyond.

POST 3 / ORIGINAL POSTEROriginal post

So i wonder if i can swap the 2000 ECU, for a 1999...

POST 4Original post

You might have to get into the technical details (pinout details as well) to find the difference...also call the ECUDoctors. They are usually very helpful. The main difference might be in the management of the vario-cam versus vario-cam plus in later cars, as well as the Motronic version and ABS/PSM management. Why are you trying to bypass the immobilizer? 99 ECU http://www.ecudoctors.com/porsche-99...261204605.html 2000+ ECU http://www.ecudoctors.com/porsche-99...261206579.html

POST 5 / ORIGINAL POSTEROriginal post

I would like to ditch it because for me, i would much rather have $10.00 dollar keys, a $400.00 alarm with remote start, and any other option i can dream up that is easily serviceable for the rest of my life, VS $400.00 Keys, and a very expensive box that is somewhat flaky, and is installed in the most water prone spot in the car. I would ditch it in a second if i could

POST 6Original post

According to "The Definitive Guide.. to the 996" - 2000 is indeed the year that Porsche switched from Motronic 5.2 to 7.2.

POST 7 / ORIGINAL POSTEROriginal post

So drive by wire i guess.... That sucks, looks like 99's are the cars to buy. You get the dual row IMS bearing, and can get rid of the immobilizer.
