New to me 2011 ML350 Bluetec with P2459 code
I just bought a ML350 Bluetec with 88,000 miles. While driving from FL to TN the CEL came on. When I was able to check the OBD2 code it had a P2459 Diesel Particulate Filer Regeneration Freq. code set. It came on at 290 miles on a 750 mile trip. Not knowing the history of this vehicle, I have no idea if it was used primarily in city driving or what...but the code did set after 290 highway miles which would have been usually where it would clean. Frankly, I don't even know what is in the DEF tank (although it has a fair level of fluid in it). Note that I did not see/feel any performance decrease in the vehicle on the trip.
I may have to replace the DPF, but I would like to hear other people's experiences. Are there any DPF cleaner fluids that are recommended?
TIA, Bill

The code reader you have is using their own "P" codes which are not M/B codes
Here are the codes for Bluetec which have 36 pages.
You must have your own scanner which can read all of your modules.

Received the Autel MaxiDiag Elite scanner. Scanned the vehicle, the MB specific code is "111500 The regeneration frequency of the diesel or gasoline particulate filter is not OK". (basically the same as the standard OBD2 code P2459). Interestingly the scanner lets me dig deeper and I found "Fault has not occurred in 2 or more drive cycles", "Freq Counter 1", "ODO Reading when first occurred 42444.0", and "ODO Reading when last occurred 42444.0".... Ahhh.... it now has 89000 miles. So figuring it was never reset, I reset the code. I'll see if it comes back, but my guess is it probably won't.
