Hey guys, as title suggests, one of my rear airbags just exploded - sounded like a bomb going off. Fortunately I had just parked up from a long and windy drive on some icy roads back home.

Had recently replaced the opposite one (should have done the pair I know but strapped for cash), so I expected it to die - but not explode!

I noticed that the suspension felt very hard on the way home, and that when I parked the bags were fully inflated (truck was raised), which I thought was clearly odd. A few minutes later - bang.

Now it is very cold here (-5 tonight), and hasn’t got above freezing today, so I expect that’s got something to do with it.

I understand how the cold could affect the integrity of an old bag, but any ideas why they were overinflated in the first place?

many thanks

Robb

HI, overinflation can be caused by a sensor or a calibration issue ... unless it's an ECU misbehaviour, you need a diagnostic tool to figure this out, eventually check if a sensor's arm is not snapped...did you disconnect the battery before you changed the bag? cos jacking it up while the air was released from a bag or unplugging a sensor can mix up calibration if the battery was connected
 
Thanks…

No I did not disconnect the battery. But the bag was replaced several weeks ago and has behaved fine - literally today was the first sign of an issue. Good to know for next time though. The self levelling sensor arms both seem in good working order. I don’t have a diagnostic tool, but there is a local garage who might.
Cheers

So I’ve put a new bag in as I needed one anyway and figured it could help diagnose the problem.

What seems to be happening is that the bag that didn’t explode isn’t inflating at all, while the new bag is inflating continually. Neither of the sensor arms are broken.

Does that narrow it down at all?

Difficult getting it plugged in for diagnostics at the moment.

Cheers,

Just to update - I emptied the bags by slowly undoing the connections from the compressor, retightened and then disconnected the electrical plugs. I then manually operated the compressor with some wires and a battery (and a diagram pulled from this site), and then just left it all unplugged at what seemed like ride height.

I’ve had to top up a few times over the past weeks, but they stay inflated for a good while.

Got a pair of new sensors. Now just need to find a nanocom.
 
Depends which flavour of Foxwell , but I would think so.
Others may be able to tell you as I have not had to use mine for this but their website or helpline should tell you.
I have had good service from them and of course it deals with all Jags and LR products, without having to pay unlock fees. although I am aware that some producers realise this competition!
