Hello,
in a w204 with the OM646.008 engine (125KW) was a ESP fault in the ic (ESP not available) and the car was in limp mode only 70kmh after 70kmh the car will stutter. Read out the fault codes and in the esp module was not a fault code. I decided to update the engine ecu (someone says the solution is to update the engine ecu). I update the engine ecu and the fault with the esp was gone and the car was able to drive 150kmh with no problems. After that i see the tank needle, sunroof was not working. The indicators in the ic flashes very fast, but alle indicators works normal only flashes fast in ic. I read the w204 again and there was a new problem now (can bus chassis off). Here are some fault codes:
U014200
C14200
C14287
22b8
22ce
23f8
20d6
203a
ecu is CRD11
A6461504372
A0054467240
HW 50.06
SW 21.07
it comes after the ecu update. The solution for 23f8 is only to coding online or full backup with ktag. But i dont have full flash for this car/engine. By the way, what has the ecu update something to do with can bus chassis off?
thanks
