Looking for some help on a c230 compressor 2003 , check engine light is not on but has a trouble PO 600 BAS/SPS can bus connection problem , i tune up the car becorse it felt like it had a miss in the engine , installed new plugs, there is no misfire codes or coil pack codes at all it still feel like it misses when slight accleoration , if anybody had a problem like that please help thanks

 

I've got the same code on my 2005 C230Kompressor. Problem is sporadic. Some times it won't start, other times it starts, runs fine except no tach, no speedo, no fuel gauge no signals no AC control, no window regulator control but runs fine. Other times it just runs normally. Does that sound like I need a new ECU?

Sorry if this has been covered before and would appreciate anyone pointing me to the right post/replies. I am new to forums and trying to fix my car on the cheap on limited fixed income.
