C250 CDI 2013
P244A engine error and loss of power (gears not changing on time etc)
Hello guys I am new here and I am also a new Mercedes owner (c250 cdi coupe 2013) and I am facing some issues with the car and would highly appreciate it if you can recommend me to go for a diagnosis to the dealership or try something different.
Had engine light on and significant loss of power (not limp mode as car would rev over 3k RPM and reach High speeds). The local garage diagnosed it with dpf pressure sensor issue and replaced the sensor and had a force regen and the issue was solved. Two weeks later my car was smoking heavily from Exhaust and would smell some burning (guessing the car was trying to force a regeneration) and then I switched off without knowing this was happening and when I turned on the car later the engine light turned on again and also significant loss of power but not limp mode. The engine code was P244A (DPF differential pressure too low) but I erased it hoping the car would return back to normal but it didn't. The engine light didn't come on again since then and I went to a Mercedes specialist to have a look at the car. He found out there was an exhaust leak near the DPF as the clamp that connects DPF to exhaust was broken and he replaced it with a new one, but then I went for a drive and the car still was not right. 2 garages I went to later said there is nothing wrong with the car as DPF readings were just fine and no other errors in the car showing. Also no leakings whatsoever. But obviously the car has lost power and I can tell when I drive it is not the same. Just to mention no forced regeneration by any of the engineers, but I went on a long drive myself and it didn't change anything.
Do you think dealership will find the actual cause of my car power loss? As there is no engine light on two weeks later.
Thank you in advance and excuse my English!
