    Hi guys,

    I have finally got the time this week to try and sort out the airbag light that has been on the dash since I bought the car.

    There is an aftermarket MOMO wheel fitted without an airbag so need to "switch" the light off. I have bought a resistor and the reset tool.

    If I have this right, I need to do the following.

    1. Remove wheel
    2. connect V+ to V- with the resistor. Can this be done with electrical tape, or do I need to solder it?
    3. Plug reset tool in and follow instructions that came with it.
    4. Light goes out, Simon is a happy bunny!
    5. Replace wheel, drive, enjoy!

    If I have missed something please feel free to tell me before I go and b***** it up.

    Cheers

    with regards to the solder/tape route allways solder + heatshrink. Takes 2 extra minutes to do and will save you taking the wheel apart again when the tape inevitably comes undone, Plus it looks nicer.

    Does this not make it an MOT fail next year? As I thought if the car was issued with an air bag, it must be fitted ????

    Supplementary restraint.

    The vehicle will fail the test if any airbag fitted as original equipment is obviously missing or defective.
    A seatbelt pre-tensioner fitted as original equipment but missing or that has obviously deployed will be a reason for failure.
    Seatbelt load limiters that are missing where fitted as standard or folding webbing type limiters that have obviously deployed are also reasons for failure.
    The vehicle will also fail if an SRS malfunction light is missing, not working or indicating a fault.


    Think you need to be looking at refitting an original wheel,
    Technically could this also rule out aftermarket 'airbag' wheels, as they are not original equipment?

    Luckily, I still have the original wheel with airbag intact, I still have about 9 months to worry about getting it refitted for test.

    In the meantime, I have just spent an hour or looking at the problem (well, about 10 minutes to take the wheel off, and 50 minutes test driving it to make sure it was OK after refitting :D )

    I took the following photos, and am just as confused now as I was before starting.

    Thanks for the replies / suggestions so far.

    Can't really answer your question as regard to which wires to fit the resister to but I suspect you will need 2 as yours is a later Z3 which were fitted with 2 stage airbags effectively 2 airbags in one. I think Jonttt is the man as he researched this when he replaced his steering wheel with a single stage airbag equipped Raid steering wheel.

    In all fairness to Jonttt he did give an answer when I posted a similar question on .net some time ago. It was because of his reply that I know that I have to connect the resistor to V+ and V-, trouble is, I don't know which wire is which!

    With the laws changing next year, it would probably be a better idea for me to live with the airbag light until then, then replace the "old" wheel. It will save having to resolder the wires back into the multiplug etc etc.
