Error code p244a7a and p244a00
Hi!
Ive E200 w212 2013 mod facelift OM651 and get error code p244a7a and p244a00. Mercedes workshop already changed sensor but error come back after a few days.
They recommended to replace DPF but highly doubt DPF itself is the problem.

A round KM 112000*
Any suggestion?

You know it's not the DPF itself then what do you think... faulty sensor telling stories to diesel ECU?
