The best solution you'll get from books at www.reliable-store.com

These are books containing info on repair, service, troubleshooting, parts info, assembling dissemble, removal, error/fault codes, wiring diagrams and everything on any vehicle- cars, atv, trucks. forklif ts, boats, excavators etc.

You need to have a fault code test run on the transmission control module (TCM) as a first step to seeing what is going on here.

Fuel draining when I park van on slope with the front raised . will start then cuts out , I have to turn engine over for 20 sec.
when I park the other way , no problems

would say cam sensor fault. engine getting warm and it playing up. would need the codes to be read but would say cam sensor.

Hi

Its the EGR valve, take it off and clean it with some carb cleaner this often works rather than buying a new one, a new one is about £150 from vauxhall, its very common but do have a go at cleaning it, I got another 2 years out of mine on a astra van. EGR is exhaust gas recycler, its kinda like a little turbo, it reburns any unburnt fuel when they go wrong you loose about 70% of the total power of the van and hates climbing hills.

I would bet without any doubt that this is the fault

if you need any advice on removing it let me know, its a simple task.

This is usually an immobiliser fault try a different ignition key

Can mean many things, automatic gearbox, emissions problems and if it flashes, it is an immobilizer fault. The car can be driven, if running ok but the engine management system should be checked ASAP. You will need EOBD diagnostic equipment to find cause. vauxhall can check this 4 u but it will cost u £47 unfortuanely but 4 that price u can get the diagnostic reader ur self the port is under the ash tray or the cover below the hand brakeRAC.htm">http://www.argos.co.uk/static/Product/partNumber/7402742/Trail/searchtext>RAC.htm

The speed-limiter is likely to be enabled via the ECU. Removing the limiter is a five-minute job if you have access to the GM Tech 2 electronic management/diagnostic tool.

If the van is yours then there's no legal requirement for the limiter. You could just book it in at a Vauxhall dealer for the limiter to be removed. They may charge you for an hour's labour though. Still worth doing in my opinion.

Sounds like a faulty cold start assistor. On top of the engine you will find an aluminium housing with four things that look like glow plugs screwed into it. These 'glow plugs' are only available complete with the housing fron Vauxhall. Approx £70 +
Airbag light is probably a fault with the seatbelt pretensioner.
Check the wiring under the seats for damage or perhaps the plugs have pulled apart.
