Hello colleagues, especially star diagnosticians and OBD experts, can someone help me or give me a hint ? I fear my S-Class needs a bit of power … Can you find the rest current with SD (or other OBD) ? And possibly also the power consumption while driving ? The following facts and FZ data: S 500 W 220 Built 2001 (PreMopf) with approx. 90 Tkm, purchased in January from 1. HD. All maintenance at Mercedes … With star diagnosis I read the following error: ECU ESP C1103-006 L 6/4 (rear right) adjustable wheel speed Current + saved C1112-001 One or more speed encoders have mutable values, wobble contact Saved Since I had tens of voltage errors in the various protocols during the first reading and I was allowed to read a few things about the importance of the voltage, I immediately donated a new battery to my car, the good 100 Ah Varta AGM – now just brand new. Many errors now did not occur and if I the car attached to my CTek, then it drives after a while completely error-free without an FM in AI or on SD / Xentry. After the 3rd or 4th drive (even if this is shorter then) comes again the error “BAS, ABS and ESP (each) workshop visit” I can have the sensor in the back right, no problem, but since I notice that my CTek after the few rides, even if these all take place on the same day, for a while again an almost empty Battery shows – with the new one ! – I guess there is a considerable current eater. Can then the voltage be responsible for the error messages ? After the charging they do not occur at first … If there is ONLY the sensor, then the always wrong messages should exist, especially with longer driving, but it then works if the charge of the battery is good. Only with further rides without new charging seems to spin again. To me that seems about s the battery sucks empty … Therefore the questions above … Who knows something about it ? Can I use Stardiagnosis (or other OBD) to determine the current consumption ? Thank you already for your advice ! Greetings Jo
