2009 Mercedes Sprinter 313CDI Fault: OBD Codes P2010 and P2BAC, Loss of Power, Coolant Leak

Model: 2009 Sprinter Fault Code: P2010 Posted: 2020-01-09 04:58

Hi everyone! I have a 2009 Mercedes-Benz Sprinter 313CDI (2143cc, 129bhp). Since September last year, after replacing the thermostat, I've been experiencing persistent issues. The van lacks power and continues to show two OBD-II diagnostic codes: P2010 and P2BAC. Additionally, the coolant level drops by approximately 50ml after just a short drive. I've taken it to several garages, where they replaced components such as the DPF, diesel particulate filter pressure sensor, and temperature sensors — but the problem persists. Despite spending significant money, no technician has been able to resolve this issue. Any technical insights or suggestions on how to diagnose or fix these codes would be greatly appreciated! Thank you in advance for your help.
