Exclamation Engine cylinder #5 fuel injection switched off??? (misfire) - N55 F32 - 10-02-2021, 08:40 AM

Hey folks,

I have a 435xi with only 2 modifications: aftermarket intercooler, oil catch can, and intake. The issue started a couple weeks back. I changed the spark plugs and ignition coils which helped some what but I'm still having misfire issues. My next step was to change all the fuel injectors but I wanted to post here first to see what people think.

102001 - Air volume, plausibility: Air volume too high.
102002 - Air volume, plausibility: Air volume too low.
108F01 - Intake plenum: Suspicion of leaks between exhaust turbocharger and intake valves.
118002 - Mixture control: Fuel-air mixture too rich.
120308 - Charging pressure control, plausibility Pressure too low.
140001 - Combustion misfires, several cylinders: Fuel injection is switched off.
140002 - Combustion misfires, several cylinders: Damaging exhaust gas after starting up.
140010 - Combustion misfires, several cylinders: detected.
140501 - Combustion misfire, cylinder 5: Fuel injection is switched off.
140502 - Combustion misfire, cylinder 5: Damaging exhaust gas after starting up.
140510 - Combustion misfire, cylinder 5: detected.
150502 - Ignition, cylinder 5: Combustion period too short.
