Airbag warning light on intermittently

John Avis by | March 25, 2019 | My 1998 318is

My warning light came on for a moment, then stayed on, then was off the following day but came on again momentarily.
As per usual, I fix one problem and another appears.

This time the airbag warning light came on for a moment, then stayed on, then was off the following day but came on again momentarily.

I read the codes and I got two errors:
1) Ignition circuit 2 - passenger tensioner: remain over limiting value
2) Fault lamp: open circuit or short circuit to ground

Time to investigate the common causes of these errors.

I did some online research and found some ways to bypass the passenger tensioner by fitting a resistor.

I also found a few posts where people had found that this error was caused by a bad connection.

I like those kind of fixes (ie. free) so crossed my fingers and looked under the seat.

All of the connections seemed to be okay but I pulled them apart and pushed them back together again and cleared the fault codes.

A month later and I have not had the light come on again, so if you have this error it's worth checking the connectors under the passenger seat.

The passenger door has been difficult to open from the outside for a long time now. Sometimes it would only open if you pushed against the door.

About me

I am a bit of a 3 series fanatic, having owned a couple of E30s and a few E36s, plus a few parts cars. I like the combination of the compact size, good performance and handling, and that they are more sports sedan than an impractical and extrovert sports car. This blog is a place to share my experience and knowledge.
