Guys,
Appreciate any help here.
I recently had the yellow airbag driver restraint system error light come on. This did not seem to be linked to moving the seat but it has been very cold recently.
Searching forums points to broken wires or plugs under the seat as a likely cause and I have had a brief check for this. I understand there is no occupancy mat as by default a car must usually have a driver for it to be moving.
I have not yet asked my friendly BMW specialist for a diagnostic check, I would guess they will confirm the I-Drive error message.
Everything looks ok and after disconnecting the battery and reseating all plugs and wiggling the loom and cables the error remains. I want to establish if this is actually the actuator faulty, a wiring issue or perhaps a stored error due to a brief disruption caused by a broken wire or similar. Trouble is, using a meter to check continuity is not a good idea as it might trigger the pyrotechnics.
My questions are:
1. Has anybody tried connecting the loom for the drivers side to the passenger actuator to establish if the fault disappears?
2. Anybody know whether it is possible to 'test' for electrical continuity in the device or the loom without the tensioner detonating? Anybody know of a pretensioner 'simulator' circuit (like for the passenger occupancy mat) that could be used to test the loom without the pretensioner connected?
3. Does the small black plug taking the 2 wires of the loom into the tensioner on the top of the tensioner 'unplug' or is it permanently attached? (I do not want to break it but it does feel quite wobbly)
4. BMMINI parts seem to supply a new pretensioner unit for around £50 (unless I have misread their parts prices) - have any others experienced them going faulty rather than just wiring?
Appreciate any pointers from others that I am sure have experienced the same issues!
Many thanks
Euan
