Hello Everyone,
I searched here over a year ago when I purchased our "new" W211 '08 E320 Bluetec to get any input of risks and failures, etc. Great car, small issues so far a 141k and didn't find many complaints here either.

I've now joined for another reason.

We are new owners of a W124 '95 E320 cabriolet. My wife wanted a red convertible and I stumbled across it cheap, so I thought. I have torn out the seats for re-upholstery and uncovered all sorts of "goodies". Under the back seat on passenger side is a module that was unplugged, part# 140 820 25 26. After Googling it, name is Seatbelt Retractor Module, sounds important, and expensive. it appears to be common on several models from '94 through '99.

What does it do?
I am curious if anyone has failure experience with this part?
Can I leave it unplugged?

I could not find anything searching the forum.

Expect more questions, and, as I work on it, hopefully info I can provide to assist others.

Great sight! Glad I found the forum where MB owners have grease under the nails.

Thanks in advance!
Brian
