Part number according to the invoice is 35411162548, which when put into a BMW part number search engine shows up as "Throttle", which is odd, but price seems to match, about 330 USD.

It comes under the throttle department as it manages the throttle opening on the main throttle body

That part number is correct as you can see here

Thanks for that chaps .I will note down the BMW part#
I know why it comes under throttle, that is what you feel like doing when you see the bill for a bit of plastic moulding, a motor armature and two teeth spitting gears. :-)

Oh brilliant. After writing in this thread the TC hasn't worked at all. I get the clacketi-clack on strtup but theb the warning light stays on. Can this unit easily be opened and is it fixable? Or is it off to the BMW dealership again...

Default Yes it can be.

Hi Fille
Sorry to hear that you have caught the TC klackiti clack flu too.

The TC unit is fixable and as I referred to in an earlier post a few days back in this thread, you can open it up. Even if you open the tiny flap door and check if the cable gear moves with a bit of pressure, you can't see the broken teeth and must unplug remove the whole unit. (two small bolts)
See this post from another forum http://forums.mg-rover.org/showthread.php?t=172482

I used this approach to get at the cogs. Broken gear teeth seems to be the main issue. He actually molded new teeth with some tough stuff and shaped them. I luckily had 2 faulty units and was able to salvage two good gears and construct one fully working unit. The smaller gear is spring loaded so remove with care and take note how it is set up before you let the spring pop out. Fiddly bit.

Good luck

Having read this thread, I thought I might add my experience.
My TC icon came on intermittently, and after a few weeks it was on permanently. Then I heard a fluttering sound on every startup and thought I had something stuck in the induction system. I explored and found the Secondary Throttle Cable broken, with some fraying, at the T C actuator gear, but no broken teeth.
Got that fixed and no flutter, no icon, but now, two weeks later, the icon comes on occasionally whilst driving along in good conditions. Looked under the little flap on the actuator and no damage visible - yet.
Just thought you might be interested. Any comment anyone???

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)

Unless it doesn't effect the diesels the same?
Do we have traction control on our diesels?
