Q: Do our seats have occupant sensors for airbag deployment? (side or front)

I beleive so. Can't say 100% tho

Both mine (front) went off and I was the only one in the car.

you mean the front driver and passenger airbags? ....

I don't believe so

that's what i thought.... i was a bit curious that's all.

I have a follow-up question...heated seat sensors
 

I had a loaner A6 ('99) for several days, & I was looking at the manual to confirm that its steering wheel was heated. (the coolest thing about that car, in my opinion, I'd pay for that option!) The wheel is heated when the seat heater is on.

The manual said the rear seats had a weight sensor & so would only activate when a body was on the seat. I wondered, what about the fronts? It didn't say. Then I wondered, what about the heated rear and/or front seats in my '02 A4 (ahh back in the day when you could get heated seats in an A4, the trade-off for having failing coil packs!) I get picky about making sure the 3 passenger heater wheels are set to the 0-position when no one's in my car. My girlfriend would think I was weird, but I had a Jetta before where 1 of the seat heaters died & I don't want to have to deal with that repair again & the way my Audi service people might mess up my seat like the VW mechanic did!

To recap after that longwinded mess - who knows if A4 seat heaters (passenger, rear seats) have weight sensors?

i don't think there are any... i got a ride on an A4 to the dealer once
 

the dial in the rear was set to mid-level before i got in and it was warm...

what would really be cool are massage and heated seats :-D the benz has this as an option i think.

ahh but benz doesn't have heated steering wheel. my dad misses that in his e500 vs. his old a6/a8

i think its a bit of a hazard to have the wheels heated if you ask me

? Not like it burns your hands off the wheel. Tho it lulled me to sleep & made me want to wiz...

There is a weight sensor or something like that in each seat; the OFRM shows it

that;s what i am afraid of... esp. when you start off for work early in the morning

Yes

Check my picture post....I was the only occupant and my bag didn't go off but the pass side did

I thought heated seat sensors are only in the rear.

I believe the deployment of the airbags are tied to the use of the seat belt
 

As RafRaf said, he was the only occupant and his airbag did not deploy. My assumption is that he was wearing his seatbelt. I believe that the car assesses the severity of impact and if it knows the seat belt is buckled, it factors in the effectivness of that before it decides to deploy the airbag or not.

Where seatbelts are not fastened, it has no clue, so the car errs on the side of caution and deploys the airbag.

cars are so smart now! :) I always buckle up...

Yeah, that's exactly it!
 

I know I'd read something about the B6 "knowing" if it should or should not deploy the airbags durring a collision. And know I remeber that, among about a million other inputs, one of the main inputs is a seatbelt useage sensor. Also coming into play are sensors detecting where the car has been hit as well as how hard and (believe it or not) whether or not the doors are locked.

Actually, that's in the manual, but I don't have it in front of me right now

Apparently, I RTFM :)

Jim, have you seen the new 04 manuals? they are more 'colorful' with the english more clear

Really? Because my 03 manual was littered with grammar mistakes and misprints
 

glad they finally got an editor to put out a good manual.
