Hello guys, I have a C200 Esprit, 1994 year, with ZV and immobilizer. Does anyone have any idea where the WFS is, or how it works? Background: I want to retrofit a radio remote control. Now the question is what I have to consider because of the WFS. And if we are on the topic… Which radio remote control would you recommend? Since I’m not so fit, this should be a vehicle-specific producer. Except you know someone in Stuttgart who installs this cheaply. Greetings maho
