I got a limp mode when driving in the 5-6000 range in third gear. I pulled over and reset the limp by turning off the car, and restarting.

I ended up with a "See Dealer" type of message on the display.

I drove 10 miles to Sonnen Porsche in Mill Valley, CA and they reset the error and stated that I had experienced a momentary rich fuel condition on both cylinder banks.

No reason was offered by dealer for the error in the fuel system.

Anybody else have this problem?
