Engine misfire
Hi Andrew Do you have any Diagnostic software ? or know someone who does ? By selecting live data I can see my injectors and whether they are operating at the same (or close volumes) I can also so see fuel rail pressure. So I don't have to get my fingers dirty unless there's and issue. My brother In-law's 540d estate is at a little over 200k and running well so mileage shouldn't be an issue I would start by checking for any leaks on the Inlet side. Unmetered air will cause a misfire Dave -

Engine misfire
Hi Dave, I don't like the sound of that. Firstly I don't know the first thing about checking fuel rail pressure, and the injectors have never been checked while I have had it. I got it at 89000 miles and its now at around 144,000. I can get the car to go as quick as I want without a miss as long as I don't want any severe acceleration. I would also be nervous about removing injectors as I have heard many horror stories about them breaking. The vacuum lines were renewed last year. It would appear the fuel sensor would be the only thing would want to try myself before i have to surrender it to a Bmw expert. thanks Paneuro. -

Engine misfire
Morning Andrew Your description sounds like fuel delivery so worth checking fuel rail pressure and sensor as a starting point. Also an Injector check (don't know how many miles you have done Inlet side all Vacuum lines and pressure hoses good (no cracks) throttle body OK Fuel filter OK Dave -

E90 320i Help With OBD II Port
Morning Tino Nothing from James just mailed him as a prod I brought an X5 E70 cheap as a project the previous owner had spent a fortune changing parts and finally lost patience with the car. The fault list was huge but after a lot of digging I discovered BMW use earth switching so started working through all the multiple earth points that helped (Not much but it helped) Next while inspecting the loom in the boot I discovered cable splices/joints covered with a clear plastic sleeve (couple of pictures attached) when I moved one it just fell apart, turns out the joints are twisted and compressed then covered with the sleeve. If moisture gets in the joints corrode (black residue) and come apart. I am not sure when BMW started doing this so maybe worth checking yours. I spent an hour or so stripping these joins and soldering then sealing with shrink wrap. I was able to see all modules for the first time and clear down all fault codes and fault memory. That was 3 years back and almost 40k still need to keep an eye on it after all it's a BMW 😁 When my sons friend brought his copy we had to set up VM ware and a Virtual Machine running Win 7 on his Win 10 Laptop initially getting the Drivers to work was a pain at first we loaded and reloaded them several times before we could get it to run cleanly. For drivers you could try ESYS (that's where my copy came from) Also check whether you need 32bit drivers or 64bit Dave -

E90 320i Help With OBD II Port
Hello there Dave 👋 I kind of put the OBD port issue on the back burner since the late time I responded, figured I'd button up the rest of the car first since I'm not getting anywhere at this time. I haven't checked the wiring on the DME side yet so I need to do that as well. Did you ever get anything back from James on the matter? I poked at the Ediabas.ini file and made some adjustments per someone else's recommendation but that didn't work either. I restored the file back to original since. I'm gonna attempt to reach out to a BMW tech from Japan to see if I can find out any more information on these 320i's and see what I can find. What are the odds that this issue is module related? I'm also wondering if there is an issue with my Cable or the drivers themselves. Where can I get a copy of just the drivers to reinstall?
