Throttle body differences




My throttle body is making loud clicking noises at idle. No other issues with it, but I'm sure its on its way out.
For some reason I can only find A 113 141 01 25 second hand.
EPC shows A 113 141 06 25 for my CL55 AMG Komp
They also look identical. Any reason I can't use 01 25?
Not sure why 06 25 isn't available from breakers etc.
If they are not interchangeable, I may pull them apart and make one good one from a second hand one and mine. I suspect I will find a worn out plastic gear.




What is different about them, is the question.
I find it odd that I cant find any second hand 06 25's
