Hi all,
I have 2 fault codes on my 2016 C200D
P0471 - Exhaust Pressure Sensor A
P2279- Intake air system leak
I’ve already previously had the DPF filter replaced due to a previous fault code but presume now the exhaust pressure sensor also needs replacing? Would this be likely to resolve both faults does anyone know?
Any advice greatly received!
 
I would suspect a fault with the EGR valve. Both codes have a link to the EGR system.
 
Not necessarily, if the EGR valve is accessible you may been able to remove and clean out. I did with a friend's Toyota Avensis D4D the other week. Solved his issue.
Did your DPF block with soot deposits
 
Oh okay so may not need a whole replacement?
I didn’t do the work myself so not sure I think it was!
