I need some help, my TT has an AWP engine code and im having several seemingly unrelated electrical problems. my code reader read p0238 so i replaced the map sensor, then it ran p0340 so i replaced the camshaft sensor. these codes keep occuring even after the sensors were replaced and sending my car into limp mode. my a/c just shut off one day and will not turn back on. the esp in the car is stuck off. it also decides when it wants to start as well. if anyone can help me please do im tired of driving a car made in 02 that i have to spend more every month in parts than a car payment for a new one would be.
