    Im pretty sure from what i have read it cannot be forced to regenerate without star at this stage, if the EML is on. My w204 250 CDI has just thrown up the same and dropped into limp mode. I would find it reallly unlikely that the DPF is blocked on mine, at 55k, with perfect operating circumstances for it to regularly regenerate. Im hoping it is just the pressure sensor.
    If anyone knows if it will attempt to regenerate with the EML off, although still in limp mode i would appreciate finding out!!

    Pretty sure that all you need to do is erase the code. I had someone in recently with the same problem on a sprinter. Turned out that the dpf had been working perfectly regenerating as required in the background but the stored fault was causing the engine light to come on and throw a drive to dealer message. I cleared the codes and it all went back to normal. He drove away and hasn't been back.

    I know it's a different engine and a manual gearbox on the sprinter but give it a try.

    I've had the differential pressure sensor changed today, the garage did a forced regen and low and behold driving home the EML comes back on and it drops back into limp mode... Any ideas for further things to consider would be appreciated!!

    Get yer codes read! It may not be the DPF that's causing the engine light to come on. No point in trying to guess. The forum is full of threads where folk have poured money and parts into what they thought was the problem, and wasn't!

    Problem is, the only fault code showing is the 'DPF too full of soot' one... -_-

    My instinct says it is extremely unlikely, but there could be a problem with the pressure pipes between the exhaust pipe / DPF and the sensor. These pipes are a combination of thin metal pipes with rubber pipe where they join to the sensor.

    If the garage has forced a regen and presumably confirmed that this was successful it is impossible for the DPF to get blocked again within the time of driving home.

    I'm afraid you need a Mercedes specialist with STAR to read the codes, not an all-makes chap with a generic reader. The proper codes will pinpoint the fault more accurately and cost you about the same as a pressure sensor.

    Its been going to a Mercedes specialist, although not my usual, and so presumably they haven't seen any other fault codes, or at least that is what they have said (no reason not to trust them..) I had wondered if the pipes were susceptible to also clogging up with soot. Its booked in again tuesday so i will just have to see... I'm still questioning 'why' the dpf has gotten blocked, if that is indeed the case, because it should be meeting the requirements quite happily to regen when needed, or if indeed there is another fault in the system which is yet to be identified.

    Not much good are they these DPF's?? :neutral:

    I've toyed with the idea of taking it out myself to attempt to manually clean it, but they look like an utter pain to do according to WIS...

    Before anyone guesses anything else, have you got the fault codes?

    We found that the issue i had post-forced regen was that the car had either not been 'reset' properly or needed a number (10?) of full-warm up drive cycles in order to clear the fault/EML/Limp mode. Low and behold on the way to the garage for them to re-investigate, it cleared itself out and did a long burn (i monitor the DPF temp with Torque app as the merc's dont tell you when they want or indeed are doing a DPF burn), and was fine for a couple more years. I then had the same issue re-emerge and bought an icarsoft, ran its DPF clean mode (i was skeptical) and that did the trick.
    One key thing to do is to not run the car with the fuel low light on, this stops dpf regen and can cause clean cycles to be missed, thus clogging beyond the point where the car can/will auto regen. Also, using kickdown/full throttle will cancel a regen, so avoid this if you have any suspicion that a regen is in progress (again, some warning would be nice Mercedes, like a little light ala' VW...)

    can a leaking manifold cause issues with the DPF filter? im having issues at the moment. recently had a new manifold on 5 weeks ago at weekend i got the DPF issues.

    Hi guys i have a mercedes a200 2015 diesel. I have a code error p2463 showing which indicates dpf filter problems.
    It occasionally goes into limp mode i cleared the code drove for a while and it drives brilliant like normal. Then when i stoo the code reappears. I clear the p2463 code and drive it again. It hasnt gone into limp mode for a while and i am adding a dpf filter fuel additive its running great but the code still reappears on start up after stopping then clearing. Is it a case of persevering and continue to keep adding a dpf cleaner additive or does anyone know a better way to clean it or do i bite the bullet and take it to a garage .
    Thanks in advance...

    If you know what to look out for, you can tell when a Mercedes is doing a regen. The engine note changes, car feels less responsive, and it holds the gears for longer as if you were in sport mode.

    Now, for lack of signs of a regen I have to give it to my BM at the moment. I’ve done over 3k miles in which time it would have done a few regens, but I kid you not there is no sign to say it is doing so.

    Many thanks its my wifes car and constantly runs with low fuel light on hence why it hasnt auto regen. I did put a dpt additive in a 3 qrter tank of fuel i took it for a long drive but used high revs n kept it in 4th. Ive since read this could be more harmful as it did go into limp mode while doing 3200 or so revs. Im going to try putting and additive in prior to filling tank and go for a long drive keeling it in 5th and speeds of 60 to 70 and see what happens . What do you think.?

    I recently got had the same code and it turned out it was the pressure sensor which needed changed cost 126 pound all in. They didn't do a force regen as I live 20 miles on motorway from garage. He told me to keep in 6th gear and do a 20 to 30 drive taking it easy no need to smash the ass out of it. They said go around 60 to 70 mph.
