Retro fit Keyless entry and start.
Question, my E Klasse have almost all equipment installed, but unfortunately not Keyless entry and start.
I'm working on to get those options instead. I can buy almost all the necessary stuff, door-handles, antennas, control module, ect for less than 500€.
BUT what about the wiring - do you know if the wiring harness in the car, already contains the necessary wires for those options ? WDD2122251A314724.

I will try to rinse/clean all plugs with contact cleaner and add contact protector.
I measured the "small" battery in the trunk and after a overnight resting.
I measure around 13V. Seems the battery is still OK. No leak or corrosion to be observed.
My guess there must be a plug with that have corrosion or a pin falled out.
