A4 Immobilizer problem

[evster]

Can anyone help? We went on holiday and left the car at airport car park for a week, I left the lights on!!! The battery was as flat as a pancake and we jump started it with the drivers door open but the rest of the car was locked, we got it going but now every time I go to start it the immobilizer won't disable, I have to disconnect the battery lead, leave for 20 seconds, connect it back on and it starts. Can anyone shed light as think it could be something silly that I'm overlooking???

Thanks

get the mt2500 scanner from snap-on and the vw/audi cartridge and manual it will guide you thru the immobilizer especially since you have not seperated the ecu or speedo it may be just a small error in the immobilizer i dont know im learning more and more everyday bout the imm
