Dpf errors

[Lenna0]

Hello
I wonder if somebody could help me . I have a problem with my mercedes c204 -(2013) 2.2d
Around a week ago when driving on motorway car went to limp mode - orange engine light on
Errors showing :
Errors : P245396
Particulate filter differential pressure sensor bank1 / internal fault
P029900 turbocharger boost pressure 1 charge pressure too low
P200c00 particulate filter/ bank 1 exess temperature
P047128 exhaust gas back pressure sensor 1 offset outside tolerance
Since been in local garage - and they cant see any leak so suggested to go to MB
Please help as i dont want to spend a fortune
Regards

Change pressure sensor located by the offside bulkhead and have your dpf cleaned or reconditioned by a DPF specialist get levels down to zero or perform a Emergency regeneration and resets of the DPF AND YOUR BACK ON THE ROAD

Thank you for your reply What about code P029900 turbocharger boost pressure 1 charge pressure too low? Is it to do with dpf issue as well?
Thanks Lena

Hi
Boost pressure to low could be down to a boost leak I would get a full smoke test on the charge air system normal issues are passenger boost hose splits. In regards to the dpf pressure sensor they have modified these and also have a modified connector.

A wee update ...
Car went to dpf doctor : dpf clean , dpf sensor working ... so no issue around dpf found
Been advised that car shows dpf error as there is low boost pressure ...
Went to mechanic : changed dpf sensor and boost pressure sensor - car still showing errors
Tomorrow solenoid will be changed so we will see
No leak found ...
no sticking vanes ...
Any ideas??..

Have u checked the vac supply to the turbo. The vac system control the turbo operation as well as other engine control eg water pump had a few vac pumps pack up. Pull the vac spinoff on the pass side at the rear run vehicle and see if u have vac supply

What fault codes are u now left with ??

All four as before plus one new dont remember name of sensor but malfunction - sensor in the engine i think responsible for letting car know about misfire ( garage has paperwork will ask on Monday what is a name of the code)...

Hi did you solve the problem P245396 i am already fighting with that almost 2months. Only this fault nothing more. When the car is warmed up and if it goes max 50km/h it goes to limp mode. Or if u turn car off for 8-10mins it get more hot and after start up and few meters it goes to limp again…
Already cleaned the dpf, 4 new sensors(yes 4already), the wiring new original with pins in connector!! Exhaust back pressure sensor new! And still if car is in town or get more warm it goes to limp… you can turn off wait like 10mins and it can go 100km without problem till u dont go slowly or stop for few mins.. sorry for my english.
