Steering wheel swap

Est-ce que je vais recevoir un voyant d'avertissement de coussin gonflable si j'échange mon volant?

Voici le DIY

À moins que vous ne mettiez pas d'airbag, je ne vois pas de quoi vous auriez l'avertissement.

Tant que vous débranchez la batterie à l'avance, vous êtes en or.

Just the negative terminal.

I switched mine out a few months back and YouTube was my friend. Took 15 minutes and I could do it in 5 now.

To be safe, leave it disconnected for 30 min or so to let the bags lose their charge. Not sure if this is necessary but it was suggested to me.

never heard of that.

Between my 330CI, 135i, 335i and my current M3, I have changed out at least 8 steering wheels and have never disconnected the battery (or ground) even once.
Never had a single issue, but.....

Regardless, I have changed the steering wheel a dozen times on E90 M3's and so far disconnecting the negative terminal provides no airbag light. Disconnect the positive terminal and it will result in an airbag light when the car is reconnected and started. I know this first hand as the first time I attempted it this was the end result and if you don't have a way to reset it, it's gonna cost you some money

yeah, it cost me $35 to have it reset last time. I think I took off the negative though...

Yeah, could be an old thing, but cant be too safe with airbags.

Exactly! I've done several. Just disconnect battery first and reconnect after finishing. The same goes for taking seats out of car since they have airbags in them too.
