BabySmart malfunctioning

When a passenger sits in the front seat of my E320 the BabySmart seems to malfunction and turns the airbag off.

Has anyone seen this problem before?
Thanks

Old thread, but current problem on my e320

Just got an '01 e320 wagon and have the same airbag malfunction.
Car seems to think a babysmart seat is attached and cuts out airbag.
Obviously no seat attached and even with passenger weight in seat the airbag does not activate. I looked under the seat and all connections are fitted and see no chaffed wires. Any idea welcomed.

This one is far more complex than my '85 300TD.
A little worried about the e320 electronics already.

You might need a new sensor. There is a DIY in the W210 stickies for r/r those.

+1 faulty seat pad sensor is the suspect here. It does not recognise full pressure only partial pressure.

Thank you for the help!

I am new to this forum (but not M-B), but I will rummage around and look for those stickys you reference. I am DIY capable, so the R&R post should get me what I need for the fix.

My 300TD has been so steadfast I have not needed to particiapte much in this forum to seek help. The most brilliant car I've ever owned, though my wife loves her new E320. Everybody happy!

Cheers!

I'm sure this isn't the problem, but let me ask. Is the passenger less than 70 pounds?

Fault code B1315 - component B48.

Bad passenger seat sensor. I checked wiring and it is all good.
$172 for the seat sensor and a few hours in the garage.
Thanks to the sticky pictorial it looks straight forward.
Worth it versus $450 for labor at the dealer, other shop wanted $250.

Ha!

The Babysmart is SUPPOSED to turn off the airbag when this child seat is installed in front passenger position.

Of course unless you have an SL or SLK, you've installed this seat in the wrong place, as it's much safer to have it in a rear seat. But at least your passenger is protected from the airbag--which has been known to kill small children when activated. You, of course, can purchase an inferior baby seat to create this problem if that's what you want.

I'm continually amazed at how many people fail to comprehend the comprehensive superiority of European automobiles.
