I recently purchased a Renntech EVM FOR MY 2021 C43, and while it seemed to open the exhaust valves the fobs would not work to control them between full open to return to stock mode or closed. Renntech is going to send out a replacement, but wondering if anyone else has had problems with this module?

Same thing is happening with mine. 2018 E63 S wagon. Flaps stuck open now. Did they get yours squared away.?

They exchanged it for another unit that is now working properly.

my cars in soft limp mode now with flaps stuck open. PE no longer working.
