Now I'm curious... if it's not controlling the EGR, what is that throttle doing? Is that acc pedal also, as I would expect, mechanically connected to the fuel delivery system? Try as I might, the only reason I can think of for this is to bring the engine RPMs down more quickly, meaning the throttle plate restricts intake when the acc pedal is released... is that how it operates?FWIW, my 240D, which has no EGR at all, also has a throttle plate connected mechanically straight to the accelerator pedal.
An MB expert could possibly explain better than I, but it would seem to help with noise too. It also seems to help them run better in the cold, and probably works as a better way for engine braking too. The later cars did away with this setup (and use an entirely different intake as well).Now I'm curious... if it's not controlling the EGR, what is that throttle doing?

TIA for expanding my education, I'm really interested in this.
Just post your pictures on any of the free places online that let you upload pictures (Picasa Web Albums, Facebook, Google for free picture upload and you'll find ton of hosting services. Once you have the pictures uploaded, use theI followed Jenettles? instructions - but without pics of knowing where and when to drill I smashed the plastic gear into 3 pieces - then saw where I needed to drill. Regardless, after gluing it back together - it works still. I have some basic pics, but at least they will help future fixers save themselves the $200-$600 depending on if they DIY or not.
My cost was $0. Time was over an hour all said and done.
I'd like to attach the pics - but don't know how. Can someone help?
I have a 2005.5 that gave Emissions Workshop! warning yesterday. Checked the code with OBD scanner and it was 2112. Researching fix and found this thread - thanks to all for the help and these posts.You can't buy "parts" because very few people are smart enough to figure out which "part" needs replacing. They wouldn't sell enough "parts" to make it worth creating a new stocking number and location.
