Tailgate Keyless antenna

Hey guys!

Unfortunately my trunk does not open when I am close to it with my key. (DS7 2019 version)

When I am holding the key close to the rear doors, it works.

In my opinion, it seems like there must be an antenna in the back of the car which is for receiving the key signal for the trunk.

Does anyone know where the antenna for the trunk is placed, whether it is possible to replace it easily and what the part number is?

Unfortunately DS won‘t give out any information regarding this and the next ds location is 100km away.

Many thanks in advance for your help!

The antenna is located in the center near the rear bumper beam. Access is difficult. The bumper harness and antenna connector need to be checked. The antenna itself is usually in good condition.

Do you have access to part numbers or DS assembly instructions, the exact location of the antenna and connectors?

Many thanks!

No, I haven’t.
