Hello everyone.
i have got a problem with my car.
When driving at ~ 2000 RPM in any gear, car starts to twitch. Its like theres not enough fuel.
But when i push pedal to floor, everythings OK.

There was two error codes.
1. Something with DPF filter.
2. glow plugs.
No other errors.

So.. Could it be DPF filter? Or what else can it be?
Somebody told me it may be EGR valve. Dunno what it is yet.
I do about 700km in week, 70% highway, so it should be enough for regeneration.
Fuel filter, air filter is new.
MPG dropped a little, but i think its because of it is cold outside...

Oh, its a n47 diesel.

I hope it is clear, what i wrote. English is not my native language.

Thank you in advance.

Could be dirty fuel filter.

With 255,000 Km on the DPF it could be clogging with ash (rather than carbon). Ash can't burn out during a regen.

If you're getting DPF errors, Id either replace it, or remove it and have it cleaned / back flushed.

Thanks Marco.

Wanted to say that this problem is random. This evening everything was normal...
