Looks like the JB4 led to my car dying. Took it to the shop to get looked at and I have been told that the software ruined the DME at the minimum. Even after removing the JB4 the car wont communicate with the DME and wont clear any codes pertaining to those faults. LUCKY ME! Looks like the car is going to be sitting around for a while....
Has this happened to anyone else or am I just on an unlucky streak?
