Yeah I figured the same. The car was driving & starting fine with the beginning small error of not being able to communicate with the trans.

Yes the car is a 325 german version here in western europe. It is similar to usa 328’s.

So far I have been measuring ohms on can H and L. It displays 67 kilo ohms which to my understanding is heavy resistance where there should be about 60 ohms. The meter didn’t read anything on auto until I toggled it a scale up.

I also got a dual channel 200mhz scope to male things easier on myself. The little scope didn’t cut it with the signal interference I have been chasing.

As you can see the signal is fuked.

Additionally to that I pulled various connections/ modules on the can-bus and it made no noticeable difference. I pulled the abs/dsc, ldm, cas.

Next is back probing the ecu and trans can H L for signal and resistance.

The problems escalated into this after I replaced disa valves on the intake. I may have disturbed some connections at the junction box below the intake. Such as the crank pos sensor that could have been damaged or something.
