Battery ran flat on my 'R' reg VW Golf gti while I was away in Australia. The alarm was disconnected a couple of years ago but now the immobiliser seems to have triggered as there is no spark or petrol feed. Is there any way to bypass the alarm/immobiliser?

Sometimes it depends on the type of allarm, if it is factory fitted they are a nightmare to do as most of the wireing for the allarm is intergrated into the loom, where as if it is an after marked alarm ( one fitted later on ) it shouldnt be to bad but still a long and complicated job to find all the wires and reconnect the originals bypassing the immobiliser/alarm if you are a complete novice this should not be attempted as you could immobilise the car completely, best thing for you to do is get an auto electrician to have a look at it for you, sorry its not much help
