Hello, I just discovered the ingition lockout code feature on my 86 325e. I can enter a code and turn the key off, and when I flip the ignition to the first position it asks for a code. If I don't enter anything or enter the wrong code, it still starts. Any ideas?

In the 1986 engine harness by the ECU connector (above the glove box), there's a 3 wire plug with a green wire on it. That wire is the actually the positive for the ignition coil and gets broken by the OBC if present. If someone along the years either bypassed that wire, or installed the 13 button OBC when the car didn't orinally cone with it, then the car will start.

The 3 wire plug should be connected to the OBC relay box mounted to the firewall under the steering column. Check this first. Some people will bypass the OBC relay when it goes bad by shorting pins on the connector."I'd probably take the E30 M3 in this case just because I love that little car, and how tanky that inline 6 is." - thecj
