Updated to 3-spoke M-sport steering wheel- air bag too soft

Hi,

I swapped 4-Spoke to 3-Spoke M Sport steering wheel on my 97 e39 and looks awesome! It has the single stage airbag (found in E38s & E39s built from 9/96 up to 3/99). However, the airbag seems strange compared to the standard wheel- the airbag is very soft whereas the old one is quite firm as in when you press the areas around the horn. It depresses when pressed and it's as if there's a cavity in there. Is this normal?

There's no airbag light in the dash and all INPA/GT1 diagnostics airbag tests pass. I've highlighted in the attached picture the areas which sink in when pressed with the finger. My 2005 X5 sports and a friend's 2000 3 series e46 have firm steering wheel airbag although the wheels are not the same.

Any pointers? Thanks!

Your airbag was probably stripped out and replaced with cottage cheese. Just don't hit anything, and you'll be fine.

Was it a brand new airbag or a used one?

It's a used one from ebay http://www.ebay.com/itm/261224410214...84.m1423.l2649

I've looked at pictures of similar single-stage steering wheels and they all appear to have airbags with a line below the BMW emblem (not the ones to the left and right of the emblem) where the airbag depresses when pressed at the bottom. It thus appears to be by design but I'd like certain verification.

Here is mine. Single stage used air bag. On a 97 540i it does have some soft spots but still feel ok.

Thanks a lot, Blingin! Could you please see this video link and compare to your airbag behavior when pressed at the part labeled SRS airbag?

if you have the M-sport steering wheel with single-stage airbag (production years 09/96-03/99), would you please compare and contrast with mine your airbag behavior when pressed at the part labled SRS airbag? Here's what mine does:

Uploaded video to youtube for easier viewing. Local dealer says this is not normal and advised to get a new airbag (a cool over $1k).

Another 540 M sports steering wheel and the airbag is as soft as mine. It's obviously by design. Thanks for the vid, z168!
