Another air bag light on

I recently changed out my battery (2003-Z4-2.5) and the airbag dash light came on along with the Airbag OFF light at the left knee of the passenger seat. Get no codes on my reader and vehicle has been through several "start/stop" cycles. Any thoughts??

Disconnect the battery. Wait 10 minutes then reconnect.
Failing that then what code reader are you using? Very unusual to have no codes at all. Do you have any other codes for unrelated modules? Anything that mentions CAN or K-bus?
 
My airbag light just came on yesterday as well. Hmmm... is this the airbag season - sort of like the cold/flu season??

I have a Blue Driver OBD2 reader and no codes popped up on mine either.

This has now become a fiasco. Z4 was to go in today to my local garage for its air bag light, in the meantime wife’s car went in for mot and service. Came back with rear screen heater and inside lights not working, took it back and its been there for 4 days. Turned out they hadn’t put back a connector properly when they changed the cabin air filter. :rofl: Wife not happy and my car now needs to wait for a new slot as they used it for her car. :headbang: However they were honest and didn’t charge for the time :thumbsup:

So now due to this, I now have to wait until after the new year to book mine in :headbang: hopefully Santa will bring me my OBD reader and will at least be able to find what the codes are. :thumbsup: Then decide what to do. Definitely finding a more reliable garage going forward. :thumbsup:
 
Update. Wife bought me a creator C410 for Christmas. Plugged it in today went to ‘airbag’ and it showed ‘93E7 under voltage’.Then went through some more sub menus and found a place to erase fault. Airbag light now on when engine not running and off when running. Is this good, has it been cured or have I just brushed the problem under the carpet and still have no working airbag?
 
It should come on for a while when you turn the ignition on as it does a self check. Can take quite a few seconds to turn off. The more you worry the longer it seems to stay on.
 
Just make sure you stare at that light each time you start the car. And then hold your breath whilst it is on.

You see your entire life go by whilst that light is on ….
 
SRS and ABS lights should stay on for around six seconds longer than the other dash lights with full ignition/ engine start.
I know this because I need to fit a timer to get around the MOT when I remove all my airbags!

The fool proof way to check if your airbags are working is to drive into a brick wall (or similar) over about 20mph. It is an expensive and apparently quite painful way of testing them though! :D

I hope all you weirdos had a great Xmas BTW! :lol:

Well that’s a bit worrying because it goes off first :? However we weirdos here had a great time, thank you, hope you did too :thumbsup:
 
I have same issue since yesterday :headbang:
So I took my car in to get the coolant tank replaced and so wondering if this could have caused it? That was done like two days before.
I have checked obvious things like battery connection and connections under seats. I tried leaving the battery disc for 15mins too.
Whilst looking under the passenger seat I found this strange box. Is it oem? Anyone know what it does?

P.s. I have ordered a proper obd to read the codes

Very unlikely to be connected to your coolant tank change unless some ham-fisted mechanic went mad in the cabin!
I believe the strange box is an occupancy sensor bypass, fitted when non-compatible seats are installed. (I am no expert on this though tbh)

So yes, get the codes and report back. Maybe they have pushed the seats right back and messed up a connection somewhere?

Many thanks Martin :thumbsup:
They are definitely the standard se seats...
I don't know what they need to do in the interior when changing coolant tank. Thought they may have disturbed a sensor on the bumper or something. Indy did mention he would dismantle the front to locate the leak. Although, not sure if he ended up doing that...

I shall report back as soon as I manage to read off the fault codes :thumbsup:

What??? :?
Take the undertray off and have a nose about! That's it.

I suspect it is more likely to be a coincidence tbh.
Sometimes it can just be a glitch. Depending what code reader you've bought you may be able to make it go away.
