I just recently got an 1995 850 Turbo, with 121K on it.

While driving to work (a 400 mile drive, I do it weekly), I got the check engine light. I pull off the interstate, check in the ops manual, and it says emissions issue.

No problem, I continue on. I have a B5234T engine. I discover the A2 socket, watch the blinking light, and I have a 4-3-6 error code, at least the way I read it, "Rear Heated Oxygen Sensor Compensation". However, that code is for the Fenix 5.2. According to vlvworld.com, the B5234T has the Motronic ECU, not the Fenix, and the Motronic doesnt have (well, I cant find it if it does), an error associated with 4-3-6.

Also, what the hell does sensor compensation mean anyway? Other than that, it runs just great.
