Hi thanks for the response Steve

I haven't spoken to the garage yet so only the note to go on for now. I'll call them on Monday and update. I read it as they think there is a primary fault with the ECU which is causing the coil to act oddly and fail. But as I say, I have no idea when a coil should be energised! or not! This might be normal for a Beat for all I know?

Your information on replacement parts is great I'll pass this on.

Sorry I cant be clearer for now

Many thanks
