P244a fault code

[travis]

Due to the current pandemic situation, we have only used our C220 for short journeys recently.
The EML has appeared and the code reader gives me the P244a fault.
I'm assuming the DPF is at fault and hasn't had chance to regenerate.
I reset the error code and the EML goes out until what seems to be a certain throttle position.
I can drive gently around 30mph zones without the light coming back on but as soon as I accelerate hard the light comes on again and it won't rev above 3000rpm.
I took it for a decent run around 60mph keeping the revs around 2500 but the error code still keeps coming back when reset.
I suspect the DPF won't regenerate if the EML is on but not sure I can get it to regenerate without the light coming back on.
Is a forced regeneration the only solution with Star?

Hi travis. Having same issues. Be interested if any other member can come up with a solution.

Please tell me the code of your engine. The mileage may be a help as well in the diagnosis.
What is the outside temp when you use the car.?

Dpf pressure sensor ?

Icarsoft MBII can force a regen

Dpf pressure sensor ?

One of my DPF pressure sensors was replaced and the dpf cleaned. All is well but I think the problem is likely to return if we can't go for an occasional blast down the motorway sometime soon.

Has it more than 1 ??

Has it more than 1 ??

I was lead to believe it has one at the inlet to the dpf and one at the outlet so it can monitor the difference.

I think you'll find 1 on the drivers side bulk head doing exactly that .
