    Motronic 1.1 O2 sensor Check Engine light???

    I have an 87 325 iS. I recently seafoam'd my car through a vacuum line and it set off my Check Engine Light. My car has a 153 dme (motronic 1.1) and my CEL blinks twice and stays lit. According to the Bentley manual, 2 blinks is an Oxygen sensor malfunction. I replaced my oxygen sensor but my CEL came back after driving for about 15 miles. I also tried switching out the O2 relay, but same result. Is it possible for my DME to reset after driving "x" amount of miles? Unplugging my battery resets the code up until about 15 miles, even if the engine is already hot. What's my next course of action? Anyone have any input? Thank you in advance.

    Did you ever figure this out? I'm experiencing the same thing. Also a 1987 325I.
