CEL
Hi all, I have a Check Engine Light that wont go away. My German marque specialist thinks the throttle body sensor is bad. apparently, the only way to replace the part is with a new TB, not just replacing the sensor. I find out the part is NLA, but found this on ebay.

Does anybody have any comments or suggestions?

Don't know if it is the answer to your CEL, but it has been part of my repair history. The early benz, with their own OBD requires someone with a history of counting flashes but the CEL and LHM can be related to the throttle body sensor mal function.
I have purchased several in 20+ years and the rebuilds, at a much reduced price are always a welcome sight !

I was able to source a used throttle body/sensor and that has fixed the CEL problem!!
