Can't think what though.
The unit is built by Bosch so I expect the BMW units come from them too. What does a BMW unit cost?
I only wish they had built them with metal gears instead of breakable plastic.
The clack clack noise you describe does sound like the gears are stuck and jumping cogs.
I didn't hear any noise in mine just the light came on to indicate a fault each time the unit packed it in.
When I opened them up I found two or three broken teeth loose inside. I even tried to break a tooth to see how tough they were and found it quite easy. NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- quality.
I can replicate those gears (in plastic) if this is a common problem. I will not guarantee steel strength but at least they will be cheap. Is it a big job to change them ? (I don't have cruise control on my car)
