Default Safety Solenoid Valves

Unfortunately, my V70 was involved in a minor fender bender that has all been repaired now. I just went to put LPG in for the first time since the accident and none would go in. I have just read my BRC System Information and Service Schedule booklet that mentions the use of emergency safety shut off solenoids and to contact my nearest dealer in the event of this happening.

I have no idea where to find my nearest BRC “dealer”, do they exist any more? Is there a way to manually reset the solenoids? The crash was very minor and didn’t go anywhere near the LPG system, just the front headlight and bumper.

Does anyone have any advice on what my next steps are?

Thanks in advance!

James.

If that's what it says, 'word-for-word' this sounds like marketing department hogwash. Got to give it to them, they're good. If it gets you to trot 'to find my nearest BRC “dealer” ', give them full marks.

If the 'bump' was a bump and no more, surely Shirley, common-sense plays a part? Else, we're into 'Big whoopsie' territory to fret. I'd be very surprised if it's more. They're referencing the one or two supply/tank solenoids to knock-off for safety's sake when the engine stops running. I doubt it's a CNG install, if it is, in a shunt, there'd be very high-pressure valve that does much the same thing. Either way, if we want something to fret over, look to not being able to shut-down petrol - gas is a helluva lot safer than being doused in liquid.

I can't see corollary here. More likely, wiring has got old or been disconnected when works were done.

As for the next steps? The LPG trade is in decline. In your prettiest frock, 'spose you should flounce down to your 'nearest BRC “dealer”. You can be sure they'd be pleased to see you.

If the tank gets hot it can cause the fill valve to stick.

To release it you need to hit the tank with a rubber mallet to release the valve

I've not come across an LPG tank with a valve that would close in the event of a minor accident. They do have safety valves designed to close if there is a sudden escape of gas - for instance the supply pipe getting broken in an accident. Some have manual valves on the tank to allow safe work on the system - could it be that a manual valve has been closed whilst at the paint shop? Or is it just the LPG pump or connection playing up on the day you tried to fill it? A local LPG installer would be the place to ask - all makes are broadly the same.

Won't try it with CNG mind, I'd have never have thought to try that.


Yes, whatever it is, it's no biggy, and doubtful it's related to the shunt per se. Something's been moved, dislodged, got old, turned-off or forgotten.

It is a fairly common thing to happen. Usually it is when the tank has been filled on a hot day and something only seen a single hole tanks rather than 4 hole tanks

Hi all, just to update you - as you have all said, the "safety solenoid valves" on the tank aren't really a thing, and alas, I went to another filling station and got LPG in absolutely fine.

I figured it was a problem with the pump, asked the chap in the shop and he told me: "no, it's been working fine all day that one has". I then put two and two together and ended up with 5.

Thanks for your input chaps.
