    Hi
    I have just been in my 2006 A4 TDI SE as a passenger and found out the seat belt light/Buzzer does not come on if the Seat belt is not fastened

    I asume that it thinks there is nobody in the Seat ?

    I have checked round for loose wires and also the air bag shut off is working ok when turned off

    have just be looking at Elsa and the passenger seat seem a complicated bit of Kit It has a Seat occupied sensor sytem built inwhich can only be Dealer repaired
    And also a seat occupied sensor also this can be changed but neads the whole seat out and stripping down

    Has anbody done any work on the Passenger seat or ideas what it could be?

    Thanks

    No not all 8P's have this function, drivers is contact based in the buckle & the passengers is 2 step based, 1st the occupation sensor has to be triggered then the buckle contact, if you have it on the drivers then it should be on the passengers aswell.

    Thanks everbody

    Once again it shows how good this Forum is

    I think I need to check on this more before I start removing seats :readit:

    It seems from the replies that some have it and some dont !!

    Can this be checked on the vin plate audi codes ?

    Mine is 8PA CLC No 7AO25567

    Or it seems it can be turned off under the software ??? If
    so I will take it to Mate and have it checked on vagcom

    thanks everbody

    Like i have said before i have seen the option in VCDS (Vagcom) and you can have all off, driver only or both on.
    check that this is enabled first. If after enabling this if the passenger seat does not bleep then i would look at teh actual seat.

    I have just been checking some VCDS code and the seat belt chime light is in there
    But i think you can only turn the buzzer off
    And does boths seats ??

    Removing seat belt chime: Seat belt warning chime is possible to disable/enable from VAG-COM: Instruments 17, Coding, Long coding helper, Seat belt warning active active/inactive

    Just a quick update

    Still not got it sorted but can anbody answer this as a bit worried about the safety issue!!!!!!!!!!!

    Is it the Seat Belt connection issue Or more worring is it the Seat Ocupied Sensor
    Is there a way of check and would a audi dealer be able to test it and say which it is

    If the system thinks there is nobody in the seat ?
    and I have a accident with a front seat passenger would the passenger airbags work???

    Anybody with seat belt air bag no how or more techincal than me please help

    Couldn't be certain mate but I think almost certainly the airbag will work whether or not there is a passenger.

    The seat belt will definitely work and bear in mind that not so long ago seat belts were all we had !

    Don't panic !!!!

    i'm a little confused about this now... i've had 2 3dr A3s (MY05 from the factory and MY06 2nd hand) and neither of them have had a chime for the passenger seat. both went mad if i drove above 10mph without my belt on (as i often fasten my belt as i'm pulling away - not safe i know, but saves me a few seconds every morning and i usually need every spare second i can get!)

    Mine chimes above 10 mph if either belt is not fastened ( assuming of course there is a passenger in the seat !!!)

    Also shows on the DIS if either belt is not fastened.

    I once put a heavy toolbox on the passenger seat and the bloody chimes went all the way home ! I could have stopped and moved it I suppose but couldn't be arsed !

    Have just checked ETKA

    There is a 'seat occupied' sensor in the seat and a 'belt latch with warning contact' obviously in the latch.

    Presumably if the sensor is ok and picks up that there is a passenger, and if the belt latch is ok and not fastened then the alarm will go off ?

    I assume therefore that if either part is faulty, then the alarm will not go off.

    Easiest one to change, I would suggest, is the latch (£55 ish).

    I could not say if any of this affects the airbag but I'm certain that it will not affect the operation of the seat belt.

    Thanks for reply I have checked the same info on Elsa there is two patrs as you say
    The seat has to be removed for both parts but the buckle is the easy one to change as the seat has to be striped to change the sensor Having it checked today with Vagcom " It should show such a major safety fault!
    What worries me is the replies that othere are the same
    IT would only be noticed if the passenger does not fasten his belt !!!!!!!!!!!!!!!!!

    Yes the buckle is the key here to if installed or not, if you dont have the contact wiring on the buckle then that side doesnt have the warning installed.

    Just found this article in the technical solutions section of Elsawin. Thought you might be interested !


    Technical solution
    Transaction No.: 2009744/3
    A3 belt warning of unoccupied front passenger seat is on
    Release date: 12-May-2006


    Problem description

    The belt warning light is on although the front passenger seat is not occupied and no objects are on the seat. ​

    The belt warning light and seat recognition sensor do not affect the belt tensioner or the airbag.


    Cause

    Because of high temperatures in the passenger compartment and sunshine the passenger seat surface is heated up. At high temperatures the seat recognition sensor responds very sensitively and as a result the belt warning can come on although the passenger seat is not occupied.​


    Production solution

    A3 3 door
    - A belt warning light and seat recognition sensor was never fitted for the passenger seat.

    A3 5 door (Sportback)
    - Belt warning light and seat recognition sensor no longer fitted for the passenger seat.
    From 04.11.2005 Chassis No. 8P 6A 095 532

    Happy New Year !!!

    This may explain why the heated seats on the facelift 08 onwards had a number of complaints from buyers saying they wernt anywhere near as warm as the pre version.

    Good find Mike.

    I dont have a New years hangover, feels great, actually getting **** done this year already.

    Yes, it is possible to turn the drivers seatbelt warning on and off via VCDS as the requirement to have a warning is not mandatory in EU regulations.

    Yes you can enable/disable via vagcom, but if you dont have the wiring installed for it, then it would be a pointless change, if your car wasnt spec'd with then coding wont change a thing.

    Nige - I think he's referring to the drivers seat belt. Surely they're all wired for that aren't they ?

    I point blankly refuse to drive anyone/anywhere unless all passengers put there belts on & its your fault if they dont put it on, its your car & your responsibility no matter how stupid the passenger is.
