Hi,

Looking to find out how to code in Collision Prevention Assist on a MY14 E350 Sedan via Vediamo, having trouble finding where it can be done. I know it can be activated on a non-distronic vehicle.

CaliBenzDriver

I do not know where this option is programmed in but look forward to learning how missing options can get massaged in.
It uses midrange radar modules located down inside the front bumper sandwiched under either HL. They look similar to the rear blind-spot sensors.

I think there are options with a single radar puck and some with two.

I have the dual version that manages braking force distance at all time ("Brake Assist") not just for extreme pedestrian emergencies.

Typically to stop the car, you just put your foot on the pedal and "Brake Assist" gently stops the car by managing pressure vs. distance. Just a way of saying consider dual pucks. ✅

(FYI: these modules circuit boards feature the solderless pins and the not so waterproof leaky connector... all easy to fix ahead of oxidation)

Still unable to figure out how. it looks like this

This is just display while I don't see what the system is doing.
W212 has several collision systems.
My 2014 has passive system, who beeps like crazy each time I change the lane on short order.
It will also add boost when I don't push the brake hard enough. But it will not do anything on its own.
Than I think it was rare option on W212 where you had PLUS option, where lane assistance would steer the car and collision assistance plus will apply brakes without driver involvement.
It is not something you can program.

You don’t understand. I’m not looking to code in the plus system. I looking to code in The european version of distance warning. Where the triangle appears on the cluster silently when too close to the car in front of you. I know you can’t code in what you’re talking about.

kajtek1

So you installed additional system who was not originally on your car and now are trying to code new hardware?
For such stuff you need real DSL guru. I know 2 of them.
1 is in Long Beach, CA, the other in Tennessee and there is really not much between. Hard to find qualified help those days. .

Sigh, there is no new hardware! The only difference is software for this, i’m not trying to enable distronic or self driving. I’m trying to enable the software eu cars have for collision prevention, which is slightly different from distance warning us cars have.

i am NOT trying to code in new hardware. Look at the video in the thread above, is there any radar guided cruise control in the assistance graphics?

My 2016 E350 has code 258 COLLIS.WARN. SYS. W/ ACTIVE BRAKE INTERV. FCW STOP. It works as Kajtek1 describes. I do not have Distronic.

Given the litigious nature in the US, I would first need to be convinced that european W212s had more elaborate versions of this software that could justifiably be deleted on US cars without NTSB notice. So far, I am not convinced, although I have an open mind.

If you can point us to another thread or source where this is discussed, it would help describe any added functionality, leading to possible coding procedure ideas.

Ok. The function of the collision prevention assist is nearly identical to distance warning US cars have. Other then the Red Triangle appearing when following to closely to the vehicle in front.


This is a W204. Notice how it DOES NOT have distronic (as it would’ve shown the vehicle ahead in the assistance graphic) but the triangle lights up (without sound) as a precaution that he/she is following too close.

In regards to your concern as to why US/NA cars don’t have it. It’s more a matter of how they designed it for the US market. Even the seatbelt chime is different for EU cars then it is for US Cars, why? Beats me, but I’m guessing it’s because we are more sensitive to such functions the car prohibits. It appears to be more a matter of taste for US customers then a DOT regulation maybe. I could be wrong here.

it greys out the link for some reason: it’s m h h auto

Here is someone else trying to code in the same function I am talking about. But how it is coded was not disclosed.

I personally had it coded into my car for one day from a E63 from Dubai when testing ILS+ coding. Mind you it had distronic, but I did not get any errors for the Collision Assyst not working. The triangle illuminated when i followed to closely to the car in front.

Another q you may be asking now is why would i want this function? I would just like to have it.

Hi,

Thank you for the reply, it appears to be a country code related issue then, interesting. Looking at MB212’s videos, Swedish spec 212’s don’t have EU collision prevention assist, i assume this is because of the snow build up on the front bumper possibly during the winter months.

I have seen a Facelift W204 having 258 (No distronic that i can see) See link below

How can I enable the rain close function? Not too sure as to why this was disabled on NA cars, if you ask me pretty useful function anywhere on planet earth.

Can't speak to the W212, but on my W211 (2005 E320 CDI) I was able to get a few things to work when I told the car to go from "US" coding to "rest of the world" coding. It allowed things to happen like:
1: fog lights stayed on when high beams were on
2: Hill hold
3: stop and go brake assist (forget what it's called)
Might be some others I'm forgetting, but the point is this: Is there a screen for the W212 that allows you to go from US to Rest of the World?

Other then the Engineering Menu via the command for changing the frequencies the radio can receive, Vedamio would be required for changing regional settings limited via software.

Or a Launch X431V+... That's what I used on my W211. It was super easy.
