Here’s a little back ground about me,,,I’ve been a German car technician now for 31 years now.I had a family owned German car repair shop for 17 years,,We worked on Mercedes,Porsche and BMW .back in the 1980’s it was kind of normal to work on 3 type of cars,,,,all the German cars we very closely built the same,,,,they all had Bosch fuel injection and ignition systems,,,,but over the years that all started to change,,,,, I then removed myself from the family business and moved on to the R/V business.,,,where I was promised the world by a friend if I came to work for him,,,,Big mistake in my life,,,but learned a lot about the diesel R/V motor homes.,,,,During the R/V years I never stopped working on German cars for old customers or old friends cars.,,,,I was always playing around with German cars,,,,,and I personally drove a old 1984 528e 5 speed trans that I put over 300k miles on before the odometer stopped working,,,,,it still had the original engine and transmission and rear differential in the car,,,,the engine finally was burning to much oil to fix,,,,,I loved that car,,,,good gas mileage and a solid car on the road,,,,After 4yrs working and being shop foreman at the R/V shop.,,,,,I got a call from a friend at my local BMW dealership,,,,they wanted me to work for them,,,,,so I moved back to the BMW dealership,,,, .Where my heart belonged with German cars.,,,,,Where I became a BMW master technician.,,,,I’ve decided to show you the life and the different types of jobs we do and see everyday working on BMW .

Any help would be super cool.
Got a 2015 535i, n55 engine. rough-ish idle that gets rougher when idling in drive, and while reversing. Got a fuel/exhaust smell coming in through the a/c vents. Only code is cylinder 6 misfire.
Changed plugs and coils, issues persist. No new codes.
Thanks in advance!

How were the spark plugs,,, were any of the spark plugs covered with fuel,,,my concern is that you said you smell fuel,,,so I’m wondering if the fuel injectors are going bad,,, or you could have the high pressure fuel pump going bad,,,, i would check the spark plugs for fuel soak and go from there.

Thanks for the reply.
None of the plugs had fuel on them.
Also, in the time since I posted my question, I was able to run ISTA+ and it showed “misfire cylinder 6 damaging exhaust gas after starting up (code 140602)”, and “misfires on multiple cylinders, damaging exhaust gas after starting up (code 140002)”.
Thanks again!

I have found sometimes just disconnecting the coils and reconnecting have worked, especially after changing both the plugs and coils. Make sure the plug connection to the coil is all the way in. Lift the connection tab, press connection into top of coil while pressing the tab back down. I believe that is where the fault codes are coming from.
I had the issue after a tune up, reconnected, cleared codes. I recently had the same issue after changing the valve cover gasket, reconnected, cleared codes.
