I have recently purchased a Vauxhall Combo 1.6 Van.

The Van Is Fitted with a factory fitted LPG kit. However I have not been
supplied with any sorts of instructions for the LPG gear. So I am not sure
what it is telling me with the various flashing lights and what not.

When I first start the van with in gas mode, it runs on petrol for a few
seconds until it reaches a predetermined temperature and it switches over to
gas with a clunk. While it is running on petrol and in gas mode a small
green light on the changeover switch flashes. Once the change-over has
occurred the green light normally goes off.

However yesterday I was driving the van when I noticed that the green light
had begun to flash having been off previously while running on gas. Once I
flicked the switch to petrol and then back to gas it ran fine on gas for a
few mins, then the green light came on solid (not flashing). Again flicking
the switch to petrol and back cured this for a few mins until I gave it a
bootful and the light started flashing and it changed over to petrol. This
continued to happen until I got home, the changeover could almost be
described as occurring when you kickdown in an automatic.

Has anyone any ideas what might be going on?

LPG Tank about 3/8s full and petrol about 1/4.

The only thing that has happened out of the ordinary was that it got quite
hot while I was stuck in traffic however the fan cut in well before the red
on the temp gauge and the temperature was back to normal when all this
kicked off.

Does anyone know of any online guides for the VX LPG stuff?


Thanks

Tom Burton

I have now managed to read the codes for the LPG thing, by connecting the
grey wire on the LPG diagnostic 4pin plug to earth and putting the ignition
on.

I get one flash followed by a two further flashes = Code 12.


Can anyone tell me what code 12 means? & More importantly some background on
how to fix it!


Tom
