, i own an Audi avant 1.9 tdi. i have an issue with mine at the moment and i have been told many different things and seem confused
in 2014 i lost my car keys and had someone come out and cut new keys and reprogramed them and the immobiliser and things have been fine until
3 weeks ago when this happened you would put your key in.it would start and then fade away and the hazards when flash and the only way you would stop
them was to undo one of the battery connections, and the key/car on dash would flash, yet you go out the next day and every thing would be fine, go out the
following day and you would have the same probelm, but now i put the key in it starts and then fades away after a few seconds, dash light flashes key/car and
hazards come on and yes to stop undo one of the battery terminals, this as been a right pain .had an mechanic out yesterday who was not helpful at all . lifted
the bonnet and said sorry i cannot work on this its an audi. as any member on this site have an idea because, i have been told battery(which is less than a year
old, earth lead, immobilser, a cluster in the dash, key, but i have contacted the person who recut the key and did reprogamed said thats not the probelm. just feel
i am hitting my head against, any advice would be greatly welcomed

 

I hate to say it but it looks like you may have to go to an Audi stealer....er... dealer and have it sorted out. It sounds to me like the key has not been programmed entirely correctly or there needs to be something programmed on the immobilizer system on the car. I'm afraid only an Audi Dealer has the equipment to do this.
