GLA 200 Reverse Camera constant recalibration each ignition start

[stevietemple999]

If you have the same issue please read the details below and
My dealership spent 3 weeks with software update, renewed camera control unit and replacement camera then to be informed this is per design is a ploy to stop complaints.
I have sent this to cs.uk@cac.mercedes-benz.com as I was informed by the dealer ship (SYTNER Sunderland UK) that MB will not resolve if a threshold is not attained
You need to raise this with MB and your dealership.

Reverse Camera repeated deployment/retraction recalibration on every ignition start.

A very frustrating and irrational function for vehicle performance.





I cannot understand the repeated Reverse Camera recalibration program at each ignition start.

The requirement to drive at less the 30KPH and not to deviate steering by 10 Deg to complete this calibration is non-sensible.



If the vehicle is driven more than 30KPH the camera retracts

Less than 20KPH the camera redeploys.

This is repeated for numerous cycles until it decides that recalibration cannot be achieved.

To design a component to fail in its lifecycle will result in expensive replacement in the future.



The software program is poorly designed and ill conceived and needs to be elevated through to the MB factory for resolution.

Options to consider in a review of the program logic.

• Do not deploy the camera in forward drive.
• Cancel the recalibration program cycle if the vehicle is in the forward drive above 30KPH.
• If the Reverse Camera needs a recalibration requirement the tolerances of GOOD/NO GOOD bandwidth need to be greater than what is in the program logic at present.

Questions

• Why does the Reverse Camera deploy even when you go directly to forward drive mode?
• For the Reverse Camera to complete a recalibration at every ignition start they must be some safety requirement in its design for the vehicle to be driven?
• Does the PARKTRONIC feature need this detailed calibration in its functionality and if errors exist in its calibration has an adverse impact on the vehicles safety features?
• Does the Reverse Camera when the car is selected to reverse require this feature and is integrated within the rear sensors for collision calibration?
• If this is not the case then why does this functionality exist and the vehicle continues to recalibrate for multiple cycles until it stops.
• If recalibration is not required then why is the feature installed in the 1st place?

Please see below the official response via Daimler on the requirements to successfully complete the recalibration.

Attached FYI at this time.

Hi there. Did you get a response from MB?

I logged two complaints about this design fault with Mercedes, but they refused to do anything, stating that "the camera works as designed".

Essentially what Mercedes is saying is that their cars are not designed to be driven during night.
