Common N54 Trouble Codes and Potential Fixes

Follow

P in front of the 4 digit code indicates a current code.

H in front of the 4 digit code indicates a historical code.

 

29CD - Misfire, cylinder 1     Typically caused by worn out spark plugs, failing coil packs, intake valve build up, or failing injectors. Replace as needed.

29CE - Misfire, cylinder 2     Typically caused by worn out spark plugs, failing coil packs, intake valve build up, or failing injectors. Replace as needed.

29D0 - Misfire, cylinder 4     Typically caused by worn out spark plugs, failing coil packs, intake valve build up, or failing injectors. Replace as needed.

29CF - Misfire cylinder 3     Typically caused by worn out spark plugs, failing coil packs, intake valve build up, or failing injectors. Replace as needed.

29D1 - Misfire, cylinder 5     Typically caused by worn out spark plugs, failing coil packs, intake valve build up, or failing injectors. Replace as needed.

29D2 - Misfire, cylinder 6     Typically caused by worn out spark plugs, failing coil packs, intake valve build up, or failing injectors. Replace as needed.

3100 - Limp Mode    Caused by the car going in to limp mode and deactivating boost control. Repair issue and reset ECU.

30FF - Pre-control boost control, boost pressure to leak from pressure line; error on loader 2; wastegate, siphon, EPDW, control line leak     Caused by a boost leak. Potential problem areas are the FMIC piping, the charge pipe, the diverter valves, or the diverter valve solenoids. Can be set by another primary code requesting limp mode.

30FE - Pre-control boost control, boost pressure to leak from pressure line; error on loader 2; wastegate, siphon, EPDW, control line leak     Caused by a boost leak. Potential problem areas are the FMIC piping, the charge pipe, the diverter valves, or the diverter valve solenoids. Can be set by another primary code requesting limp mode.

2A87 - VANOS plausibility    Caused by dirty or failing VANOS solenoids. Clean or replace as need.

2A7C - VANOS plausibility    Caused by dirty or failing VANOS solenoids. Clean or replace as need.

2C31 - Lambda probe in front of catalytic converter, trimming control    Typically caused by the wrong O2 sensors in the wrong downpipe or a major exhaust leak. Grey wire loom goes to the back pipe, black wire loom goes to the front pipe.

2C32 - Lambda probe in front of catalytic converter, trimming control    Typically caused by the wrong O2 sensors in the wrong downpipe or a major exhaust leak. Grey wire loom goes to the back pipe, black wire loom goes to the front pipe.

29E1 - Fuel mixture control 2    Typically caused by the wrong O2 sensors in the wrong downpipe or a major exhaust leak. Grey wire loom goes to the back pipe, black wire loom goes to the front pipe.

29E0 - Fuel mixture control 1    Typically caused by the wrong O2 sensors in the wrong downpipe or a major exhaust leak. Grey wire loom goes to the back pipe, black wire loom goes to the front pipe.

2AAF - Fuel pump, plausibility    Typically caused by a failing or failed fuel pump. Repair or replace as needed.

29F4 - Catalytic converter conversion 1    Typically caused by having high flow cat downpipes or catless downpipes and no tuning. Run a Stage 2 map.

29F5 - Catalytic converter conversion 2    Typically caused by having high flow cat downpipes or catless downpipes and no tuning. Run a Stage 2 map.

2C9F - Lambda probe heating behind catalytic converter 2, input signal    Typically caused by a failing or failed O2 sensor. Replace as needed. 

2EF4: Coolant thermostat (Temp below regulating temperature)  In some cases this code can be an indication of a failing water pump. 

P2C7E: O2 sensor post catalytic converter, trim control (Bank1) In some cases this code can be caused by a failing sensor or exhaust leak.
