they have the right diagnostic equipment, so its a case of working something out

 

Are you saying that your engine starts right up and then dies? Do you know what an immoblizer light is? There might be a yellow car flashing in your instrument cluster which means the key your using isn't recognized by the vehicles electronics. If you have a spare key see if that one works.
Other than that, take it to the dealer or get the VAG COM software.

 

yeah thats exatly what happens. I dont have a spare key, the previouse owner never handed in the spares when she traded it in. I do know a place to get a new key made. I will check with the garage tomorrow to see if this is a possibility

 

You have to get a key with an immobilizer chip in it, then have the dealer program it to the car.
NOTE you have to have ALL your keys when they program them.

 

Sucks to say Stealership maybe your only option
