DB9 VOLANTE ROLL BAR DEPLOYMENT
Discussion
Haha, lucky for me the top was down during this event. Hey DB9Volantedriver, how much did the service manual set you back, I have been looking for a resource of information on the db9 without success so far. Just finished the spark plugs/coil job and I could have sure used a little assistance from a service manual!

I think it was around $10 on the Aston website for a one day (24 hour) pass. I just downloaded onto my PC the DB9 manuals which are PDFsThe db9 is a great driving car, but it is unfortunately plagued with some piss poor technologies, the roll bars seeming to be the latest installment to my list.
My 10 year old clk allows you to retract the rollbar after deployment, and when the top is up the level of deployment is lower than if the roof is down.

I guess how daft that is or isn't depends on how much roll over protection is afforded by a fabric roof?My 10 year old clk allows you to retract the rollbar after deployment, and when the top is up the level of deployment is lower than if the roof is down.
Surely the issue is not the height they go up, but how readily they go up? If the car was actually rolling over, the last thing I would be worried about would be replacing the rear window

I agree. I don't mind if they function during a roll over, I would prefer it. However, when they go off because I am getting on the gas mid corner, it has me wondering why they are this sensitive.
Definitely worth taking up with your dealer IMO, though I suspect it's another case of electronics that could be better...Well,
That was fun...didn't realize that traction control off was the key to undesired deployment, but it happened to me tonight while doing a little sideways action...thankfully with the top down in this glorious California weather.
Time to go into the workshop manual and figure out how to get them back down...UPDATE - I didn't find any instructions for "ratcheting" the system back down...does somebody have the secret to this?
I just went 2200 miles of VERY spirited driving, previously had the car on the race track with the DSC system on, and more recently with it off and no deployment...then one sideways move on the street and BOOM!
I know there was a service action on this, but I didn't see my car in the VIN range...I am still going to check with AM.

they are designed to go to a similar height as the windscreen, the hood provides no protection what so everThe parts manual shows them as a cartridge with one part no so I presume are one time usage
To trigger them the electronics has got to see feedback from several sensors the suggest it could roll
I've had "air" loads of times in my S with no issues, its sideways "slippage" that gets it going
Now drifting would tell the yaw sensor you are going side ways with steering, throttle and abs contradicting it (OP I suspect that is what trigger them - No?)

Two things...one, it appears my '06 was built before the changeover, so I should be able to retract them and in fact found the catch release to unlock them and push them back down, but will have to disassemble the rear seats to get at the catch that holds them down.
Two...I was not in Sport Mode when they deployed, but DSC was off. I think if I had been in Sport Mode they would not have deployed as it has a much higher tolerance for "playing".
The other big lesson is that the trim covers are damned expensive...I found one (a little worse for wear from being hit by multiple cars)...still looking for the other. They are 250 British Pounds EACH and are 6 weeks on special order only...OUCH!!!

Good work
At least ydou are not looking for two new cartridges and a glass screen
Apparently if the ROPS pierces the window, that means an entirely new fabric top as the windscreen is bonded into the roof fabric...not replacable! WOW...ANOTHER 3K Pounds for that...plus labor...I feel SOOOO lucky..to live in California and have the top down in January.At least ydou are not looking for two new cartridges and a glass screen
I still haven't located the 2nd trim piece, so I am looking into 3D printing to have one made...Yankee ingenuity at work.
Pics to follow with the process if I am successful at retracting the bars and manufacturing and recovering the trim in leather at a local upholstery shop
