I got code11 on Pin14. I reset it 2 weeks ago and got "limp home" mode. It won't go over 1500rpm. No other codes on pin8 and pin14. this code11 keeps on coming back. I really don't want to bring it to dealership. I would like to get some advice and info from the forum because of owners actual experiences and Mercedes Benz experts.

Since i got this car 2years ago. I have replaced the following: ac compressor & evap, MAF sensor, SOV, EGR, wiring harness, ETA rebuilt, OVP, new interstate battery, brake light switch, coils, wire set and sparkplugs. I love driving this car, It idles 750rpm without vibration and power is there when i need it.

The "limp home" mode happens after driving the car for 30minutes. To clear it, i pull over and turn-off engine for 30-45secs and start it , i can drive it again. This "limp home" mode happens intermittent. Sometimes, after the car warm up in 30mins or after driving for 1hour.

Also, i will be replacing the voltage regulator this weekend as the ABS, SRS warning lights are "on" when i turn on the blower and the blower does not blow air.

Thank you!
