I have a 2007 mini cooper s with 92,000. I live in chicago and have had the cold weather throttle body installed and its been really cold and im in limp mode. i have p0341 camshaft position sensor code and p1637 and 1638 throttle vavle codes. The last couple of days i have started it up and instantly gave it some gas and and i can keep it out of limp mode. That is not the case today, i can not get it out of limp mode and i even tried to clear the codes and drive it but they instantly came back on start up. Any body have any ideas where i should start?

 

Nobody has any ideas????
