Hi guys and girls,
I need some expert advise on a problem I'm having with my Astra 1.6 SXi sport hatch (2007)
It's 2.5 years old (July 2007). In July 2008 I got it Lpg converted at a specialist mechanic in Poland (recommended to me by my in laws who have all had their cars done there). When I brought it back with all the paperwork and stuff my mechanic told me it was the best lpg job he'd seen. It's been running perfectly for over a year (over 10.000 miles)
A few weeks ago it starting stalling in the morning, after about 5 minutes from a cold start. At first I worried it was the Lpg when auto changing from petrol but then ran it on petrol only and it did the same fault. Every single day at exactly the same time.
I took i to the dealer (as in warranty) and asked him to have a look. His computers came up with no fault so he blamed the Lpg. I explained that I tried it with the lpg switched off but had the same problem but he told me I had to take it back to the guys that installed it (impossible).
After a dissagreement I called a Lpg fitter here in the UK who suggested that with my system (BRC) all we needed to do was
a) pull the fuse out to disconnect it and if still problems
b) run it on petrol for a few miles and then try a cold start again.
My dealers service guys tried and the fault was still there.
The dealer called today to say that Vauxhall technicians suggester changing the crank shaft sensor as they may be faulty with Astras. Dealer tried this but same problem. Vauxhall are now saying that because they don't recommend Lpg on Astras I need to have it looked at at my own expense at an LPG specialist. I will do this and ask for written proof that it is not the fault of the LPG.
1) Does anyone know if such a document is possible and can be used as proof?
The dealers seems to suggest that even if proved that the fault is with the car Vauxhall might declare that the warranty is void because of the conversion. Before getting it converted I called the customer services and they assure me the warranty will not be void (unless of course fault is with LPG system itself)!
2) Does any one know if this could be the case?
3) Does anyone know what the fault might be?
My own mechanic suggested it could be the air mask meter, but he can't deal because of warranty and he is not LPG specialist.
Any help would be MUCH appreciated...
PS I'm not very technical!
