how to turn on front sensors in c450 2016?

Is it optioned? You are talking about the ultrasonic sensors that makes the car beep when approaching an obstacle right? Isn't that automatically on everytime you start the vehicle?

my car does have front sensors, yet once i get close to a wall, they do not beep.

another question would be is that a normal engine sound, ticking? its a c450/c43 amg 2016

If you are talking about the ticking sound from the injectors then yes it is normal, I am unable to open that file for some reason, do you mind uploading to youtube and then linking it here?

If it doesn't beep then you might want to scan the car with a scanner for codes, if there are any. Make sure Parktronic off is not select. the icon looks like this. image from Google: https://lh3.googleusercontent.com/pr...roaTjxZUEqfYq8

i do not have these buttons. the ones i have are the following:

Hmmm, is the vehicle bought new or you just bought it used, do you know and certain that it has front sensors? Most likely you know how the sensors look right? They are those circle indents. https://i.ebayimg.com/images/g/0DkAA...aN/s-l1200.jpg

the car is bought used and yes it has sensors.

Understood, time to scan the car for codes if any is present with a scanner like XENTRY.

Do you see these little bars with the Parktornic logo in the middle https://encrypted-tbn0.gstatic.com/i...23Ty1eqYSTsw&s

RamiZein

No i cant find those strips

They are either incorrectly wired or disabled in the car coding. Should automatically turn on when going below a certain speed and show the bars light up as you approach an obstacle.

You might also be missing the module entirely if the bumper was replaced.

Another question, is that a normal engine noise when the front engine cover is open?

Are you able to upload to youtube, I still can't play that video, this time it simply says the video is not accessible in my region (I am in Canada).

As for the parking sensor situation, you will need to connect a scanner and look for codes. If like the other forum member mentioned, the bumper was replaced, they might had indeed replaced it with one that has sensors but the car didn't originally came with sensors, you have rear sensors by chance? At least if you do have rear sensors, it might be real sensors in the front but still has a possibility of both front and rear bumpers replaced.

i took it to a shop. apparently those sensor holes are closed and do not have any sensors connected to it. the car came originally with sensors as i believe but doesnt have that now sadly. and no i do not have any back sensors.

Sorry to hear that, I guess the sad news is the front bumper was indeed replaced. I wonder why the front bumper was replaced : ( other than if it was an accident.
