Need Help: "System Fault Visit Workshop" displayed

[haroldterk]

Friday I picked up my new 997C2 Coupe. After going through the orientation and going thru the TMPS settings. When the dealer and I started the car up, we got 2 warnings: Tire low and the service warning (exclamation point!) notice: System Fault Visit Workshop. We thought (incorrectly) that they were related. (When an adjustment or change is made to the TMPS setting) a few minutes are need for the TMPS system to learn. So I drove away that evening, and the TMPS corrected itself with 5 minutes, but the warning did not.

Went in for service on Tuesday: The diagnostics / technician said it was a bad trunk release module (causes the error message and the rear parking lights and license plates lights to be on when the motor is running and the headlight light switch is off.

After the part was overnighted. I returned Wednesday to have that module installed – required the removal of the entire front bumper assembly and headlights! Afterwards, everything appeared fine – no warnings for the rest of day and evening.

This morning when I started the car again, same exact warning “System Fault Visit Workshop” was displayed!

So, has any Rennteamers know or heard of this problem? And what, if any, is the culprit and solution.

1 week old, 500 miles and already 2 visits to the service department, with another planned for Monday.

Porsche has had some electrical issues with the 997 and 987 models and have been working with these issues. The major concern is the system failure message that comes on the instrument cluster and that is usually caused by the front control unit. There has been a change with the software and the new ones are much better. A couple of gremlins will show up in a new model but there are different control units to fix those problems now.

The visit work shop warning can be caused by many things but the most common cause right now is a bad front end control unit. The problem manifests it self as faults for the front trunk latch, although there is nothing wrong with it. There is an updated control unit and Porsche has technical information about it.
