Done the 'Right' thing and tried to get a key cut so I had a spare in case I lose my only one.
Used my usual guy, spent all day walking around town waiting for the call to say it's done, but noooo, the 75 isn't playing ball! Again!
Anyway, short version, he rang up to say they can't code it as there is an issue with the car. He showed me when I got to his garage.
He plugged in his coding equipment, and when he selects 'Keys cut' he said it should tell him which 'slot' of five my original is programmed in. The readout displayed error, not complete.
He explained he can try and code he new one and guess which of the five positions to pick. He said if he picks the one that my key is programmed on, it will wipe out my old key and replace it with my new one, leaving me still with one key and £150 lighter.
I said go for it, he suggested position 5, but it didn't work and wouldn't allow the new key to be programmed.
He said there is a fault with the car or ECU because it isn't allowing a new key to be programmed?
At least I didn't have to pay for the new key as he can re use it I assume as it hadn't been cut yet.
So, where can I go from here?
Will BMW have any joy?
He asked me if there is any more documents with the car, and all I have is the cars key code number.
