Hello,

does anyone knows how to open Engineering mode / Secret menu CLA250 (year 2015)? Is it possible, I have read in other forums that in new models it is impossible without programming?
Please help.

No known tricks yet for 2015 and later

You need to scroll thru your main display in the instrument cluster via the keys on the steering wheel. There is a menu that should change from c to f.

There was a recent post in another thread ... if the dealer service tech forgets to put back the lock out then key sequences work

Typically no lockouts for the 14s using ntg4.5/4.7
The newer ones using ntg5.x could have lockouts in place (unless the tech forgets to relock after a service job, as noted previously)
