C180 Coupe AMG-Line Premium Plus 1.6 petrol
Greetings from 2023! Bought my 2014 c204 in April 2022 and it’s now January 2023 and it has 59k on the clock. I’ve got the 1.6 petrol c180 (living in London ulez zone) and it’s been great! i had a w246 night edition sport plus before this.
One tip that wasn’t mentioned (may be an obvious one) pressing the windscreen wash button 5 times with headlights on will activate the headlight washers (provided they’re fitted).
Another amazing feature that a lot of people
won’t know about, is the fog light function with the intelligent light system. When activating the rear fog light, the front headlights will automatically adjust down and out to the side and won’t automatically engage the main beam in order to get the best visibility in fog!
Another minor thing people may not know about is the little stalk pointing towards you under the gauge cluster, twist it at night and it will adjust the interior dash lights brightness
Reading this thread was great. Just very annoyed about the auto tilt mirrors not working as it’s so annoying having to manually adjust every time, especially with them being so slow.

Possibly a new secret discovered while I was trying to access the service menu. I pressed "call hangup" instead of "call answer" and the hazards flashed once. When repeated, the hazards flashed twice. No idea what it changed, can't find anything on Google about this. Turn signals still flash three times, unlock/lock sequence (lights and sound) still the same, etc.
Steps:
1. Insert key
2. Turn key to position 1
3. Press and hold the "call end" button on steering wheel
4. Immediately press and hold the "ok" button on steering wheel
5. After about 5 seconds the hazards will flash either once or twice

Sorry to revive this GREAT Thread, but when I try to re-sync my Sunroof, should I hold it (when fully opened and closed) on No.1 (Manual), or No. 2 (Automatic)? Like past the resistance point, or what? Because whatever I try to do, the sunroof always does the whole stuttering motion in the closing process.
