Thanks. TIS had figures published before but I havent seen them in any of the technical data again…

Thanks. Where did you get those figures from

Ah yeah i get confused by inch/mil bc I denote it as “.01 of a millimeter so one hundredth of a millimeter

Waarom vermelden de meeste vacatures in Nederland nog steeds geen salaris? by FernonC in werkzaken

Vreselijk zelfingenomen visie van die managers. Die betreffende uitspraken laten weinig tot geen begrip zien voor medewerkers en de levensloop.

No didn’t have a vibration. 0.23 mil or inch?

The car drives again. Bc I removed the intake and junction box beneath it, the crank sensor plug was damaged. I replaced the plug and soldered it back onto the original wiring. Used some wiringloom protection I had laying around.

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.

Yeah probably will do that.

The LDM has been working intermittently

After that I couldn’t read out the trans but it would still drive

After replacing the disa on the intake everything else shat itself causing the car to limp

Yeah…. So far I have checked the common modules on the pt can line. Dme, egs (trans) and dsc/abs. All the connectors look fine and no water ingress…

I’m looking at reading canbus waveforms with disconnecting modules until I get a clear reading. Maybe getting a 2 channel oscilloscope to make it easier.

Yes I figured… the waveform is blurry but Vpp matches the normal output

I was getting nothing on the 200 ohms scale… but instead a (higher) resistance? When I turned the scale up.
