I have a porsche 996 carrera 4 with tiptronic. All may waring lights are flashing!
This is a 996 2003 with tiptronic and cabrio. When ever the engine is cold and I start it, all the warning lights start flashing, the spoiler engages and disengages continuously. I get a all the failure messages on the onboard computer. The paddle shifters don't work, etc. Once the car warms up...about 5 minutes, It all STOPS and will not come on again until it sits and gets cold. (about three hours) Any Ideas?
Clean & tighten your battery terminals. Use a terminal cleaner/brush and do a good job.
