Glad they seem to be fairly reliable as I haven't found many threads on people having issues online. It's pretty scary as I noticed it's pretty expensive through FCP, but a little bit cheaper through Schmiedmann.

My guess is the S65/85 are more prone to failure due to their location inside the V of the engine where things can get pretty hot. Either that or the internal components are different from the S54 throttle actuator. For the S54, I would not hesitate to replace with a used, good working unit since they are pretty reliable and easy to access.

Wondered about this as well, you hear about it often on E9x M3's/E6x M5/6's.

Has anyone had their throttle body actuator fail on them?

That's exactly how my system is operating, except I'm on 10W-60, thanks!

I haven’t noticed any loss in cooling after switching from CSF to new OE (street driving only). What was noticeable was the significant weight difference.
