Hi Freepo

My Corsa has always had the LPG switch set to LPG. When cold the car
automatically starts on petrol and only once it has warmed up to a certain
degree does it change to gas. For the first few seconds, up to a couple of
minutes if it is really cold, the light is flashing to indicate that,
although switched for gas, it is running on petrol.

Yeah, mine has the same system, On a very cold night a few weeks ago
It was still flashing even after about 5 miles, I thought the system
was broken for not having change it to LPG, I switched to petrol then
back to LPG and it ran fine on LPG from then on. It was then that I
decided to always start on petrol and flick the switch myself. I
found that flicking to LPG too soon caused the engine to stutter when
changing gear, but it can be changed to LPG as soon as the car is on
an open road in top gear No matter how soon after starting the car it
is. and because there are no more gear changes it will run fine on
LPG onwards.

I guess I should have waited on that cold night to see if it did
eventually change to LPG (stop flashing) itself. I might try it
sometime.

Basically what I'm saying is you can be waiting quite some time for
the system to automatically change to LPG, and doing it manually
(starting on petrol) you can do it sooner thus save petrol.

I read what you wrote on your emissions and the DVLA.
My Corsa, 2005 1.2 SXi, has the low level of VED of £15, and this is
confirmed atwww.parkers.co.uk/road-tax. It may be that your car has the older engine
and as such the higher emissions.

Can you tell me what your V5 states is your CO2 g/km please?
My car is the older version and does have higher emmissions, the
problem is it is registered with the DVLA as having the petrol rated
emmissions of 146g/km when it should be 138 g/km the LPG rate.

Your car is LPG rated 119 g/km
The petrol version of your car is rated 139 g/km

that's a difference of 20 g/km between the two which is surprising as
mine is only a difference of 8 g/km between the two.

I did not know that Vauxhall had improved the engines. I'm quite
annoyed I only just found this out from you. Had I realised, I would
have bought a 2005 model. Maybe I'll look for one and then sell my
one.

BTW what does the exhaust emmission warning light look like? Not sure
if I have that on my car.
