BWM 320d E91/E90 Glow plug DIY trouble shooting part 2

200 miles ago I replaced all 4 glowplugs with new. However in this cold spell it is struggling to start so let's go back and see what's gone wrong.

Interesting video , modern diesels are a joy to work on aren't they 😅 egrs dpfs multiple sensors etc. You have a very thorough way of diagnosing which is refreshing to watch , much better than part swopping until the fault is fixed.

Thanks for kind feedback. I've never been a parts swapper until fixed person. That can be an expensive and unrewarding method.
