I need to replace a combination switch in a 97 E320.

Is this relatively easy?

Any special tools required?

How do I remove the cover on top of Airbag to begin with? Where are the screws for the cover?

 

easy.

from the back of steering wheel.

 

Sleepwalker,

There are two holes in the back of the steering wheel. I cannot see inside the holes, but It feels that I can engage a mid-size flat head screw drive. It is very tight both clockwise and counterclockwise. The tip of my screww driver was bent. I did not want to apply too much force for the fear of breaking something.

What is insde the wholes and how do I get the airbag cover out?

Do you have any pictures or diagrams?

Thank you very much.

 

not flathead.

it is torx.

 

Thank you sleepwalker,

I have to go and buy the tool. Should I use alen wrench type torx or screww driver type torx. Do you happen to know what size?

Thanks.

 

torx 30 if am not mistaken.

at least 70mm long because it goes deep. too long will not give you enough space also.

the L-type got more power on it.

just disconnect the battery while doing it so you won't have a mercedes-benz mark logo on your forehead if ever it deployed accidentally.

if need radio code, just give me your radio serial number.

 

Thank you Sleepwalker.

Good News: I replaced the combination switch and it is working fine.

Bad News: When I start the car, the SRS red warning light goes off for a fraction of a second and It comes back on and stays on. Yes I checked and rechecked that the wire plug is connected to the airbag unint. Disconnected and reconnected the battery. Now it seems that I have a bigger problem to solve. Do you have any ideas Sleepwalker? Thanks for all your help.

 

did you mess up with that clockspring unit? check if you didn't pull it too tight while steering.

there's an open circuit.

 

Sleepwalker,

I just bought a new clockspring and replaced the old one. The SRS warning light still comes on.

Do you have any other advice?

 

just delete the fault code.

take it to the place where they got the scanner.
