2006 e60 exploded Seatbelt pretensioner

Hi..
Driver seat takes two tensioner and the one on left hand side exploded.
Is there any way to bypass the exploded belt tensioner? So that i can do away with ' ding!' Every time I get on, off the car?

Thanks

The tensioner is a small powder charge or a gas charge and is combusted by a flash from the igniter. The igniter is a simple filament, like a 3V 2 cell flashlight bulb, imbedded in a thin metal capsule with some flash powder packed around it. Once that is powered by the safety system control unit it is an open circuit and the control unit lights the light and the gong sounds. If you plug in a new tensioner or suitable substitute you will still need to access and clear the control unit with one of the computer scan tools. Safety systems are not self clearing for the circuits of the airbags, tensioners, and power interrupts typically. The warnings for system voltage and warning light circuits are typically self resetting.

I have INPA to clear the fault.
So, it sounds like there's no way to clear the error until I plug a new tensioner? or
I can CREATE a circuit with register as others do to solve the faulty tensioner code for working tensioner?
What I wanted to check was "substitute" to deceive the SRS sys'.
It seems that no part suppler is selling this unit in U.S. due to regulation and I have to bring it from Europe.

The igniter circuit load is 2 ohms.

Why can't you get a junkyard part?
Is your car not a US spec model?

Tks

Quite honestly, I was hopelessly posted a question but thanks to the help from Aber, it is now fixed.
Real first time that I found a solution by posting a question on the forum.

Cannibalized a register from my daughter's broken toy, and it is finally a 'dong' free bimmer

Were you driving the car when the seatbelt buckle tensioner activated? What damage, if any, was done to vehicle.

I know the safety systems components are staged at different sensed decelerative force levels. I'm just curious about how this one item came to deploy.

Actually I bought this car at 25K mile and it is reaching 60K miles now.
Previous owner got 'allegedly' a minor accident and driver's side air bag and 2 tensioners on driver's seat deployed.
He fixed all except this tensioner. When I scanned before I bought 9AF6 code was there and I thought that I could easily get the part which turned out to be not.
So I had been keeping it as it is until yesterday.

How hard is it to get things shipped into you from the USA?

I think I am O.K. with just one tensioner on the right hand side(seat belt buckle unit)
It's an explosive material and it maybe hard to get this shipped...
