I was not thinking with my comments on the distributor, its just a simple electronic unit superceding the old contact points system. Most of the 3fse systems I have seen use MAP but with so many changes over all the years of production anything is possible. If not already done check the manifold ...

Check the 5v reference circuit is not pulled to ground; often a cause of no mil lamp display and loss off coms Cheers Ron W

Hi Sky chicken You have answered Liviu's question re tools, wiring diagrams and basic diagnostic skills follow, silver bullet fixes are rare. Scan for com codes, pick an accessible module, scope can signals, being a BMW I would start in the trunk [water intrusion] check powers and grounds, activate ...

Eddie If you are in the repair game you wont regret it, Start with simple basic testing to get the hang of it measure known good vehicles, use the Automotive guided tests to start, forget triggers and increase the time scales you will soon see how it all works. Cheers Ron W
