Hi All,
I have recently been having some issues with my 2012 W204 C250 CDI 7G automatic.
I have done around 4500 miles since I have got the car but as of last week I started to notice some issues with the gears not changing correctly and it appearing to be in limp mode, however there was no EML displayed so I was unsure if it could have been gearbox related. I decided to scan the codes and to my surprise the following were showing:
1. P245512 - The input for differential pressure sensor 1 in the diesel or gasoline particulate filter has a short circuit to positive
2. P024872 - Output 2 for the low-pressure turbocharger has a malfunction. The actuator does not close.
After driving it for an hour after resetting the codes the EML came on and I had the error code P227962 (A leak was detected in the intake air system). After conducting some research on that code I went to check the intercooler hose which is normally the charge air hose that goes into the intercooler. Much to my surprise I could visually see that it had split. So I have now ordered a new replacement from MB hoping that will be the last of that error code.
I reset the codes again and did some further research and I concluded the differential pressure sensor also needing replacing as the live data was displaying -0.02 mBar for B28/8 which seemed odd. I managed to locate a Bosch sensor and I replaced it. The new values for B28/8 are now 0.04 mBar on idle and it increases when accelerating, and now no more P245512 error code.
Does anyone know if the P024872 code is related to the split that I have in the intercooler hose? or is it a totally unrelated matter? It just seems weird how all 3 errors appeared at the same time.
The other question which may be related or unrelated is relating to the live values I obtained when idling & driving the car. The B19/9 (Temperature Sensor Upstream of Particulate Filter) is constantly displaying 650°C when idling & driving. Does this relate to a faulty sensor? Am I right in thinking it will be in a constant state of DPF regeneration? As my DPF fill level is at 0% (supposedly).
Thank you for reading,
Kas
