Error code 44A4 after replacing glow system
Just finished replacing all in my glow system on my N57 - gliow plugs, moduld, harness from moduld to glow plugs and power cable from alternator to module. Now error code 44A4 pops up, - Glow plug cylinder 3 activation.
Guess this may indicate bad glow plug, even tough it’s brand new. I replaced all the glow plugs Bosch, while the rest of the components were OEM. Should I try to replace the glow plug, as it’s cheap and easy access withour removing the intake manifold again, or could something else cause the fault code? I don’t have any other error codes. |

If you clear the code does it come back?
Have you checked and re-checked all the connections? |

Naturally I had a lot of error codes when I started the car first time after replacing everything, and after clearing these I had no error codes on next diagnotics test.
The 44A4 showed up after a 10 minutes test drive, and clearing it doesn’t help. The wire connector to the glow plug on cylinder 3 is holding tight, which points me to a faulty glow plug, even though it’s brand new among the others. At least the car started smoothly this morning in -12 celsius, without any rough idle. |

Just realized I’ve been looking at the wrong glow plug, so the error was easy to find.
The cable socket housing is loose around the head of the glow plug. it’s wobbly and I can turn it around the glow plug. Guess I have a reason to take the car back to the shop. |
