I'll be replacing one soon. Any issues / procedures ??
Standard 'poverty' class.

Also I've noticed so comparatively expensive. Is there such a demand? Even from breakers (if you find any with one ) and even ebay they cost many hundreds. Older models are much cheaper??? and even the new w204 cheaper than w203. Just don't get it. perhaps more 'careless' people driving w203's :shock:

when i took mine off, i did this
disconnected the battery
remove 2 x torx via the back of the wheel
pull airbag forward, disconnect the center airbag firing wire
disconnect wheel control wires

STORE the airbag face up, so that if it did missfire, it will not send the metal back plate in your direction.

return power when all is complete and the job is done, if you connect up power and you have not connected the firing wires, then you will get the SRS error that will need star to reset

Do not turn on the ignition with it unplugged,,you will need STAR if you do to turn off the warning

have removed many, many without disconnecting battery. as mark and malcolm say avoid turning ignition on with bag disconnected. i suppose familiarity breeds contempt but we never worry too much about which way up an unplugged airbag faces :neutral:

storage, transport and disposal of airbags fall under hazardous materials regulation. so reputable breakers may not be inclinded to retail airbags or seat belt retractors. this may explain high prices asked by those prepared to ignore regulation and take the risk.

What about refitting?
Already got the old one off (has blown).
And the engine has been running with it still connected - while blown. But NOT disconnected. Is there a difference?

switches, frame etc. fine to refit, just need to replace airbag module + cover.
But two questions.
IS there a difference (to star?) between off or blown
When refitting could it re-blow as it had been triggered.

i.e. refit after reset. Or reset THEN refit?

Nobody repairs the older model cars, hense no demand for older model airbags.

W203 are in demand as plenty of salvage W203s are still being repaired.

You refit the air bag and the module..the module controls the air bag, so it needs resetting to allow the system to recognise it. When replacing blown air bags and the control module always disconnect the battery, have only ever seen one blowing on a citroen, the mechanic was luckily in the foot well reconnecting to the old module.. so battery off, then get the airbag light reset.. a disconnected air bag cannot blow.. as the detonator needs a power supply to activate it ..hence the module..
