Hello dear S-Class Forum, since I am writing here for the first time, I would like to introduce myself briefly. My name is Oliver and I drive a W126 500SE year of construction 80, silver metallic (yes, one of the absolutely first ), which I inherited from my uncle. The car has 260,000Km down and is generally in a good, well maintained condition (has a little rust at the bottom of the door, but the rear window frame is absolutely clean, the interior equipment (Velour anthracite) is like new). the age of 29 I want to continue driving the vehicle and in the future as a classic car continue to maintain and maintain. Unfortunately the car has some problems: 1) The ABS lamp is permanently on (so also NOT off when you start the engine and is immediately on even after the battery is disconnected). My screwdriver is definitely overwhelmed with this problem “The ABS can’t be read out” The ABS also definitely doesn’t work What can I do? Had already the overload protection relay What can I still do? And another question: 2) Can I retrofit a cruise control for my vehicle? Since it is 80 years old and has K-Jettronic, there is of course no ASR, or electro-hydraulic actuator. Did I see something like this in the bay here: Tempomat retrofit kit Would you recommend this to me? Or where do I get a cruise control? How expensive is the installation and where should I have it done? What can soet be done? 3) The idle speed is always about 1500 revolutions at the cold start. How high is it with you? PS: As soon as I have time again, I will introduce myself and my car correctly ;D MfG Olli
