So after 9 months of joyful ownership my 1er has broken. It came up with drivetrain error and lost all power. BMW assist came out and took it to the dealers 4 days ago, but they can't find the problem...
They did find a cracked spark plug casing??! But think something is a miss with the timing...
Lets hope it's fixed soon, as I've been given a Seat Leon Eco flex diesel thing as a replacement until they can source a BMW for me!
