Last week i had problem with misfire cylinder 5 ( don't remember code but it was misfire cylinder 5 , spark duration to short).I changed ignition coil and problem gone. Yesterday during hard acceleration service light become and now i have a lot more of following codes:29D1 MISFIRINGS CYLINDER 5, 2E1C IGNITION CYLINDER 5,
30A4 IGNITION COIL CYLINDER 5 INPUT SIGNAL, 2C78 LAMBDA PROBE CAT 2, 29CD MISFIRINGS CYLINDER 1, 2E18 IGNITION CYLINDER 1, 30A0 IGNITION COIL CYLINDER 1 INPUT SIGNAL, 2C77 LAMDA PROBE BEHIND CAT, 2FDB, 29CF MISFIRING CYLINDER 3, 29CC MISFIRING SEVERAL CYLINDERS . My are juice box+ 100% ,solenoid bypass.

Bring the JB+ to 50%

How old are your spark plugs? IF they have more then 25,000 miles they likely need replacement.

40.000 miles on spark plugs,tuned since 28.000. I ordered spark plugs and coils, and i will set jb+ to 50%. thx

hey having these exact same codes and my plugs have only 8000 miles on them i have jb4 DCI and catless dps running on map 5 what is causing this issue and what are the cat codes caused by? could i really of burned thru my plugs in 8K miless????

After 8k miles I would check the plug before changing them or just try to swap your coil with another cylinder to see if the misfire follow the coil.

Since you have a JB+ the easiest test is to remove the JB+ and undo the solenoid bypass. Do a few WOT runs and see what happens. Since you are misfiring on three different cylinders, and your plugs are not that old, sounds like a sensor might be going/is bad. There are typically 5 sensors that seem to go bad on the N54: two TMAP sensors (charge pipe and manifold), two O2 sensors, and the low pressure fuel sensor. I would rule out the low pressure fuel sensor cause you would have different codes.

Lastly your HPFP could be on it's way out.

Changed coils and plugs, everything was fine till today:
2E35 Injection valve cylinder 6, input signal
Error will cause a warning light
Error is currently present
Test conditions have been completed
29D2 Misfirings, cylinder 6
Error will cause a warning light
Error is currently present
Test conditions have been completed
Signal or value below threshold
