Been having problems with my immobiliser,
battery died a few months ago and as it was dying the immobiliser would kick in after 2 seconds of starting which I put down to the weak battery,
put a new battery on but had the same problem since, meaning to start the car I have to disconnect the battery for 20 seconds and as soon as I switch it off I have to do the same thing again to restart it,
Its been to the garage twice and put on vag com and 50/504a and on vag com it says the key signal is too weak, the instrument panel is clear of faults, and on the 50/50 software says the ecu is in static mode and won't talk to the immobiliser!!!!
anyone any ideas?
i have tried a more powerful battery but that still has the problem so I know it's not a battery fault and my key has no battery in it
