Amgedition

Hi All have been cruising this great site but have just recently joined, so thanks guys i have had loads of help from members.

So i have a 2011 ml300 cdi with a 100,000km and the same fault code has been coming on for the past few months i have replaced lots and to no avail. and there is nothing on xentry or TIPS about this fault code which is making it even harder the code is 148A00 pulled with current xentry software, and description is
"the number of times the regeneration of the diesel particulate filter was too high"
the car has had pressure sensor, oil change correct oil, forced regen, dpf recalibrated, and ash content all recently checked and within tolerance. to be honest i think throwing a filter isnt the answer but seems its all i have left.

thanks guys for taking the time to read the post and any help would help greatly Mr AMG

Hello AmgEdition,

I'm french and I have the same problem on the the same car (ML 300CDI Grand Edition 2011) . Do you find an issue ?
Thanks to answer me if you send this message

Maybe the differential pressure sensor needs to be "trained".

Fly, the DPF sensor has its own code.

If the DPF sender is broken, yes, but if it needs training, not sure there is any error code for that.

Hello,
Have you fixed the problem?
My car C320 is coming over and over..the same error 148A00.Even if DPF was cleaned, differential sensor changed, oil changed.
In plus before the error, the car is having an sound like in below video from min 0:46.
Is sound like air but the hoses are ok.
i'm suspecting the EGR valve. Anny opinion please?
