ABS and ESP warning lights on your Mercedes W204 can be scary—and expensive—if you don’t know the real cause. In this video, I break down fault codes C1140 and C1145 and explain why they’re usually NOT a bad ABS module. The real issue is corrosion on specific pins in the ABS/ESP control unit connector, which causes high resistance, BAS faults, and steering angle sensor errors. I’ll explain what fails, why it’s common on W204s, and how to fix it the right way so the lights don’t come back. Save time, save money, and avoid unnecessary parts replacement.
