I bought a used c4s cab and now I am having issues with the stop/start feature. The battery was replaced a week ago and for a few days, it was working okay until yesterday. Any thoughts?

 

Could be your alternator is bad. Get it checked out.

 

could be a speed sensor or loose wire in the suspension somewhere. did you get a psm failure as well?

 

Thanks for the advice PorscheCrazy. She's in the shop now. I am not sure BulldogR6 if it's the speed sensor or loose wiring but I am having the Porsche technician take care of it. Like what most of the purist say, they do not like using it but you would still want that feature to work if you need it.

 

Let us know what the tech says. Automatic Stop Start (***) is good to use when cruising, gives better gas mileage.
