I didn’t order this car, it was off the lot, and I’d not have added the star myself but the car came with augmented navigation and a few other options that we did want. In between seeing the car and buying it I checked on refitting Distronic and only bought the car having found that it is possible.

On the center HUD display, I project the speed and it shows a carrot on the periphery that shows the speed of the vehicle in front once it is sensed…so that’s the setting I use. If the carrot is below the set speed, you are closing.

Yes you are right, your car has some sort of radar just not the full package. If you compare cars prior to 2019 that doesn't have distronic the MB star is 3D and hollow-ish, while the 2019 cars you still get somewhat a 3D star but it still sticks out and not flush. Cars with distronic just like the pre-2019 cars will have it completely flush.

I am assuming the reason why MB don't offer illuminated star for distronic equipped vehicles due to this reason, it is flush, I guess they can illuminate the ring but it can't illuminate the actual star due to the amount of radars and sensors within the emblem.

I believe (not fully sure) it uses that radar and the camera used for augmented reality or the camera right above the star (although that is likely just used for the 360 camera function), cars without distronic can option auto brake (my C43 without distronic has auto brake although distronic brings the full active brake assist). That camera near the top of the windshield also helps with the intelligent light system to automatically turn on and off highbeam when it senses traffic and if you have adaptive high beam assist plus it turns off individual LEDs while keeping the rest of the high beam on.

After all it’s not as if something gets removed or downgraded when you add the star. I’m leaning towards adding Distronic and see what happens.

I see, sorry I wasn't able to answer your question with the previous information provided.

Distronic radar which is mounted behind the star, is much longer range and uses a different beam shape than the CPA radar, which is usually bumper mounted, can be one or 2 units, and is offset to one side.

I have seen people add distronic to cars that don't have it, by fitting all the sensors and coding all the associated modules, but it is not a dealer supported thing and must be done aftermarket. When we requested to add features like that it was almost always shot down by MB engineering. We had to ask them to turn on the options for a trailer hitch if a customer bought one to install on an ML/GLE, there's just nothing a dealer can do on their own.

My personal experience with LED bulb on garage door opener is that those does interfere with the garage door opener which decrease the range (even those specifically designed for garage door opener still affects the range, just not as bad as non garage door model), so I wonder if the same thing applies to the LED on the illuminated star which might interfere with the long range radar used with the Active Distance Assist DISTRONIC.

It looks like what you are activating is the distronic PRO, not distronic PLUS. I believe only the PLUS uses the long range radar, so you might now have issue with the PRO one.

There are 2 Versions of Distronic in modern cars, Distronic PRO & Distronic Plus.

The main differences are:
- Distronic Plus uses a Long range radar sensor & requires the flat MB heated "distronic" star as everyone calls it.(except in the w213 where distronic pro also uses this star) Distronic plus is always bundled with driver assistance pack. This distronic has extra features such as cross traffic assist & works at a higher speed (100mph+)and longer range. For short range detection the stereo camera is used.

- Distronic Pro uses the already installed CPA radar in all modern Mercedes vehicles (except 205/253/213). This is a mid range radar sensor so it does not require the special "distronic MB star" and can work with the standard 3D star, even if illuminated. Distronic PRO is adaptive cruise control only, however in my opinion works just as good as distronic plus, in traffic even comes to complete stop and takes off again.

In some European markets Distronic PRO is offered as a option when configuring the vehicle, however in the UK for example MB force you into spending more money on driver assistance pack.

To retrofit Distronic Pro in a vehicle with a CPA radar all that needs changing is the steering buttons & then some coding which we can do remotely.

I hope this clears things up

Raj
