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.

It seems to have cleared the problem, or at least [touch wood] it has not
re-occurred.

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 at www.parkers.co.uk/road-tax . When I first tried the site I was
getting a return of £55 for 6 months and £100 for 12 months, after a bit of
investigating I found that I was entering the details wrong, I had quoted
the date of registration from 9 June 2003 - 30 June 2004. A bit of further
checking and entering the car as a 2003 - 2006 with the model as 1.2 16V SXi
(80ps) Bi-fuel then it came back with the level of £15 per year. I know
that when I ordered my car, August 2004, Vauxhall were in the process of
introducing a new engine and the LPG option was suspended and not available
to order until December 2004. It may be that your car has the older engine
and as such the higher emissions.

My experience with the fuel economy is kind of like yours although filling
it seems to be a bit temperamental, sometimes taking only 32 litres when it
has run out and other times, when not totally empty, will take around 45
litres so fuel economy varies wildly between 21 and 69 mpg averaging around
38mpg over the 69,000 miles it has done. LPG used to be 29.9 a litre, at
the cheapest station I use, when I bought it and now is 48.9 there.

A good forum for help/information is http://www.lpgforum.co.uk/.

Just looking for some advice here.
Car is a 2005 Vauxhall Corsa 1.2 with 67,000 miles on the clock, factory
fit
LPG system. A few weeks ago when I started it on a cold morning it was
not
running well and the "Exhaust Emission" warning light flashed a few times
and then stayed on, I had managed to cover about 1/4 mile, thought it
might
be dual fuelling so switched over to petrol. Restarted engine and the
same
again, limping back home, car did not have enough power to pull up a
small
incline. Managed to switch it over to LPG where it picked up and ran
fine.
Travelled to work switching between petrol and LPG and no problems at
all.
The problem raised its head again on Tuesday after being parked all day,
it
was very cold, around freezing, again after re-starting engine and all
fine.
Car has been into the garage who reported back 7 error codes, mainly to
do
with ignition/misfires varying across all the cylinders and one of the O2
sensors. They are blaming the LPG system but I thought that because it
is
running fine on LPG and the problem only shows when on petrol it must be
something else. Anyone got any ideas?
Thanks

With my my very short experience of owning a corsa LPG so far I have
decided it is best to always start on petrol, and only swap to gas
when it is warmed up a bit. If I switch to LPG too early as soon as I
change gear the engine stutters and switches over to petrol itself
(flashing LPG light) - because of this I wait until I am on the open
road in 5th gear before changing to LPG.

When I read what you wrote it looks as though you start it on LPG even
on a cold day. Do you know if the problem still occurs if you start
on petrol and only switch to gas when the engine is warm?
