FCW177 Radar Calibration Parameter Reset

[hassank1]

Hello everybody. I was trying to setup Distronic Pro on my W177 and everything was going well until I reset the FCW177 calibration to initial factory state. The problem is that I have not saved these measurements before the reset and now I cannot calibrate the sensor. When I try to do that I receive the error code B182700. I have attached an image of the error code. Help would be highly appreciated.

I have done some research and as I understand it, I have to do the Initial Startup setup from Xentry, but the problem that if I want to do this I need Online Xentry Diagnosis because it has to receive and send info from/to Mercedes. I would appreciate it a lot if somebody could help me with that.

Have you done the Backup of codings before the reset?
I think you will need to backup coding>do a reset>apply the backed up coding>then use Xentry for calibration.

This is how I did it and it works.

The backup is not available.

Post VIN I will find a. aed for your car.

I have the same error, my car has lost the MPC calibration. I have Xentry but I don't have the calibration machine. So now when I start the car I get error messages for everything that uses MPC.

Is there a way to calibrate the car without taking it to Mercedes?

Can anyone help?

Yes, you can calibrate it with Xentry or DTS Monaco.

After coding you need to do the initial startup and then you need to do the camera calibration as @wojciech says. I did most of this work, it's very simple. The best option is to save a backup in DTS FCW before you start bypassing the initial Xentry setup.
