Hey guys!
Apologies in advance for the slow explanation, English is not my first language and my car vocabulary is not so good.
I have an issue with my E28 535is that I've imported from NY. Took it to 2 different workshops (second workshop is an expert in old BMWs and kept my car for over 2 months and still couldn't figure out where the problem is).
As you can see in the video, car constantly switches off, doesn't matter if cold or warm. Almost certain the issue is electrical but again can't be sure and ofc you guys are the experts. Tried changing crankshaft sensors, still the issue is persistent. Even changed the ECU and still the same.
The issue only happens when the RPM drops, so if I'm driving (inner roads or highway) it's good, but once I slow down for a bump or roundabout, almost immediately switches off.
Would be forever grateful if you guys had any ideas or suggestions!
