Mercedes Star Diagnostic C4 SD Connect C4 multiplexer




Problem description:
2003 CL600 throwing P0120 (throttle position sensor); dash display reads ESP and Distronic errors (white, not red); check engine light is intermittent, and car is in limp mode. Have replaced throttle pedal assembly, passenger coil pack (found a cracked coil), and plugs. 

Found oil around some of the plugs, and at 39K mi they looked like they had 139K miles on them…ugly. Also spotted a vac hose with a hole, and had a cracked nipple on the air sensor closest to the throttle body.

Car also idles rough occasionally…have checked fuses and relays for all the above-named suspects…even going under rear seat on driver’s side. I’m confused because the idle makes me think the issue is mechanical in nature…but the car behaves differently when my OBDII scanner is connected.

Tool to use and how to do:

you have to get a Xentry DAS
without that you will spend money scanning with these idiots at MB dealer garage
and probably never find


just get a mercedes star diagnostic C4 (C5 is not confirmed as real yet)
