    Thumbs down Seat belt and lights behaviour in accident

    Hi All,

    I've got a 58 plate S3 Sportback and coming home from work on the M4 on Thursday night (after I'd had the car a little under 3 weeks!) somebody slammed into the back of it. Damage doesn't appear to be severe:





    The reason that I'm posting is that I was a bit alarmed at how the car behaved in the accident so thought I'd share in case anybody is unlucky enough to find themselves in the same situation.

    The accident was fairly standard motorway stuff - I was in lane 3 doing about 70mph when somebody further up the road braked hard for some reason forcing all of the cars behind to do the same. All of the cars in front of me were modern BMW's and Audi's, the car behind me was a 1992 Toyota Starlet - no prizes for guessing which car failed to stop.

    The Toyota hit me hard enough to trigger some of the Audi's accident responses - it cut off the fuel, fired the seat belt pretensioner on the driver's seat belt, switched on the hazard lights and unlocked the doors. Thankfully it didn't trigger any of the airbags. This all seems sensible enough but left me with a couple of problems. The seat belt pretensioner pulls you so tightly back into the seat that you can't breathe and hence your natural reaction is to unbuckle the seat belt - the seat belt is now deceased and cannot be used again (I don't know if this is normal or a fault). The second problem was that I could not turn off the hazard lights - I pressed the hazard lights button many times to no effect, tried holding the button (this makes the hazards flash faster) and turned the ignition off and on several times but nothing changed (they are off now so I can only presume that there is some kind of timer in control).

    By the time that I had given up on the seat belt and lights the traffic in lanes 1 and 2 was travelling at a fair speed again which left me with the fun task of getting from lane 3 to the hard shoulder across two fast moving lanes of traffic in a car with no functioning seat belt or indicators - this almost certainly put me at a greater risk of injury than the original accident!

    Anyway, my (completely unprofessional) advice to anyone who finds themselves in the same situation would be:
    1. If possible, do not unbuckle the seat belt until you are on the hard shoulder.
    2. Don't waste your time trying to turn off the hazard lights
    3. In the moments immediately after the accident all 3 lanes will be virtually stationary - catch your breath, turn the ignition back on and get your a** over to the hard shoulder.

    Hopefully none of you will ever need to follow this!

    One positive note - my insurance company has sent me a brand spanking new Peugeot RCZ to use while they are repairing the S3!

    Jason

    Just discovered that the passenger seat belt is also jammed solid so presumably the pretensioner fired in that as well even though it wasn't in use which seems a little odd. Oh well, that will be 2 replacement seat belts needed then!

    Glad you are OK, and thanks for sharing it with us.

    Im guessing the system is set that if you get hit as hard as you did it assumes you may not be moving on so quickly. Not ideal when you have to make it across 2 lanes.

    Best get it onto computer / VCDS to see what's what. Keep us informed; cheers, W

    Thanks, it's being picked up tomorrow morning and for some reason they are taking it to Portsmouth to repair it. If I get a chance I'll scan it with VCDS just for curiosity - I suspect it will throw up a LOT of errors!

    Yes, that was what I figured. It's just a shame that we can't have seatbelts that protect us in an accident but still provide some basic protection afterwards.

    first things first glad no one got hurt in the accident, my work mate had a terrible accident on a motorway he was stationary in traffic and someone hit him full force at 70mph from the rear car was of course a complete write off as you can imagine but the safety devices saved his life a testament to modern car design and safety systems
    off the road boohoo anyone got a gearbox for me lol!!

    Totally agree - we are fortunate enough to have a staggering amount of protection in a modern car which is often taken for granted. It must be an impossible task to set these systems up to work in the best way in all situations and the priority has to be protecting the occupants of the car during the accident, not worrying about whether things work after the accident.

    Thanks, ultimately walking away from any accident is all that really matters.

    Technically the accident only involved myself and the Toyota since we were the only vehicles to make contact - I stopped and the Toyota didn't so it's viewed as a pretty straightforward accident with full responsibility on the Toyota. My insurance company (Quote Me Happy) have passed it to one of these dodgy no fault accident handling companies who currently seem to be trying to spend as much money as possible - the hire car they provided is being charged to the insurer's at 200 quid a day!

    Thats weird for passengers but logical in the same thought, but tell me, does your car have seatbelt warning fitted, as then it would have seat occupancy sensor & I wonder if then it would detect if the passenger seat is not in use & thus not fired the tensioner for that side.

    I've just checked this - there is a seatbelt warning light on the dash but I think it only checks the drivers seat. If I fasten the drivers seatbelt so the light goes out and then sit on the passenger seat with no seatbelt on the light doesn't come back on. If there is no sensor for the passenger seatbelt that would explain why it had to fire the tensioners for both sides.

    While I was in there I ran a quid VCDS scan - this is rather more red text than I like to see:



    Most of the faults seem to be just logged events of action taken during the accident ("Crash - Engine Shut-Down Activated", "Crash Data from Belt Tensioner Stored", etc.) so I'm not too concerned.

    For anybody interested in such things the full log is here (ignore the radio errors - I fitted the original stereo back in so all of the coding is wrong):

    If there is no actual wire on the passenger seat belt clip, then it wont have seat belt warning & thus no occupancy sensor.

    It's amazing how the ECU in Audi's act when there in an accident. It's very interesting , And the Fact it shuts the engine Down and even keeps Crash data for an Audi crash investigator.

    It's common for the recoil part of the belt to lock so the belt length stays the same when you undo it. I'm not sure if it's mechanical or acted by a pyro (I guess the latter) so something will need changed in the b-pillar too.

    Hi, I have managed to rescue my mate's Audi S3 Seatbelt after the passenger side airbag/pre-tensioner fired randomly whilst driving normally! You need to strip off the side trim in the back, unbolt the seatbelt unit (17mm bolt) and lift slightly to get it away from the car. Give the unit a shake and you will hear the rattle of a lot ball bearings. These are the physical locking mechanism....

    Next job is to remove the loose bearings by unscrewing the only phillips screw on the unit (on the shiny metal block on top of the seatbelt reel) prise the metal tabs off and get your hands ready to catch a load of big steel balls! You now need to prise off the plastic cap on the side of the reel unit (easily done with a flat screwdriver) which reveals a load of small plastic cogs. Just below this mechanism you will find the final ball bearing which will be in a small plastic holder with a little door on the side. Discard this ball and low and behold it will now allow you to pull the belt out again. The seatbelt will now function like a traditional inertia reel belt (locking with sudden jerks).

    This will allow you to get mobile again at least enough to get it properly sorted for optimum safety. There is no way to reset the pre-tensioner, the only way to sort that out is to replace the unit.

    Finally, after an agonisingly slow 4 weeks spent driving a Peugeot, it's back . Complete with shiny new rear end and working seat belts. Just in time for the snow!

    Cheers all for the tips and support after the accident

    One last question on the subject - am I going mad or have they stuck the S3 badge back on in completely the wrong place?

    That's what I thought! Apart from the badge position I can't really fault the work - the colour match is perfect, I'd be amazed if anybody could tell it's not the original bumper.
