Fitted my New Steering Wheel

[DaveP]

Just checking, coding of the modules or coding out certain airbags out to remove warning lights?

Before you do any research, I'd head here to do some reading: https://z4-forum.com/forum/viewtopic.php?p=2083084

enuff_zed was working on my car at the time, and consensus among clever people seems to be that it's not possible on a prefacelift like mine. There are instructions for how to do it on a facelift in that thread.

What year is your car? Is it an early model?

Yes, it's a 53 plate.

I'm late to the game here, but your link to the connectors is really helpful as I was drawing a blank on what to search for.

Sadly your resistor link is broken. Can you confirm what value you bought for the 2x resistors please?

Glad this was helpful to someone!

The resistors I used didn't actually show a value - I just got one that was loosely branded as 'fits BMW'.

I did end up using the one in the MOMO Box for one of the resistors - I think you can work out what resistance they are easily enough and just get a second? Alternatively this is basically identical to what I used for the second airbag resistor;

Coming back to this, are you 100% that it requires resistors on BOTH airbag wires?

I've been researching furiously on the solve for the E46 to find more detail, and nobody seems to mention using multiple resistors.

I think I'm just going to buy a used slipring cable (I butchered mine to use it for the horn), and wire everything back into that. I just need to figure out if I need more than the one resistor that came in the box with the wheel and boss.

No worries. I can't see how you'd get away without two resistors - the Z4 is a dual-stage airbag, so if either plug no longer sees the same resistance value as the airbag it will throw a fault. The E46 wheel only has a single-stage airbag so only one resistor. D

You could always try it, wont harm anything, you'll just get a fault light on the dash. I'd personally not bother and just get a couple of (?)2.5ohm resistors and be done with it!

Sounds sensible to me. I think it was 2.2ohm from memory.

Update to this. Was searching the part # (32301097246) for the airbag loom/connector on Ebay, and it looks to be an identical part to the E46. This would suggest to me that both run dual-stage airbags, unless I'm being thick?

Well, to update this, I must be a complete berk. I adapted an old loom to wire in my horn and 2x 2.2ohm resistors, checked that the correct value was showing, fitted to the car, and still can't bloody clear the airbag light.
