Hello,

I recently bought a 2017 SLC 300 which I believe is a R172 (rebranded SLK). It has an interior that looks like https://di-uploads-pod3.dealerinspir...UPE-CH06-D.jpg (no AMG logo on the screen though )

I am wondering if there is a way to enable engineering mode? I've done a few google searches and haven't seen up with any working codes. Some codes like hangup+7+9 just result in a loud beep with nothing occurring on the screen.

Thank you.
