regular maintenance

These codes mean your diesel engine needs regular maintenance besides oil changes.

Faults suggested items are :

Fuel filter
Exhaust sensor
(Air filter...)

I have recently installed new air filters, but I have this code before then. When you say exhaust sensor, would it be this one?

Yes this is a good candidate BUT IMAGINE THAT... if you don't have enough rail fuel injected you don't get enough exhaust pressure... Meaning deal with FILTER as your first step.

Do yourself a favor... do not buy counterfeit look alike parts. The better parts will save your time + money. The junk parts will fail before 6 month if you're lucky.
