P2138 error code 
Solved
Mini Cooper 2011 Base hatchback 130000 miles
I have a 2138 error code which indicates throttle pedal. After 3 weeks of troubleshooting, it turned out tobe the brake light switch. While 2138 puts the car in limp mode, disconnecting the BLS and clearing the code, takes the car out of limp mode. Reconnect the switch and the error reappear when you press the brake pedal. While you have no limp mode, you also don't have brake lights. Tried an aftermarket switch which lasted 3 days. Dealer wanted $98 for genuine part, AutohausAZ charged $45+8 for shipping.

Update: the new switch did not help. Found out a bad relay in the DME. $2000 repair. Bypassing the brake switch with a generic push switch, relay and resistor ( to trick the DME from throwing codes). Pull the original switch, covered with foil and E tape. DME will never see it. Clear code. Limp mode gone. Saved a ton.

Will not idle without playing with gas pedal and skips badly. Exhaust smells very rich. Have new throttle body, plugs, wires, coil put in new cam, lifters gears chain tensioner oil pump, fuel pump n a whole lot of other things. When i get it to go down the road it run pretty good until i come to a stop, then it all happens again.
