P2002 Error Code on GLK250?
Folks who have had this code.... what was your outcome? CEL came on about a week ago and cleared it. Came back on after about 350 miles and taking it to the shop tomorrow. I am not sure if I should expect to be replacing the DPF or if it just needs a good cleaning.
In those 350 miles, I used archoil treatment and drove several trips on sport mode. I have already replaced just about everything on this car except the DPF and engine itself 😵💫. Currently at 155k miles and have not been able to located a reputable shop to perform a delete. Advice? Experience? Anything?

I took it to my shop this past week and had them initiate a forced regen which cleared it, but came back on the very next day. Their next step is to replace it as they don't do DPF cleanings. I would likely need to ship it off somewhere and reinstall.... this car has been a NIGHTMARE!

It should have also gotten a new DPF, along with those other things. I know mine did, and it says so under the hood where the dealer placed the AEM sticker.
You might just need a new DPF sensor somewhere in the system, and not a new DPF. You might need to find a better Euro diesel shop to diagnose exactly which sensor is acting up.
If the above doesn't work, then it might be time to do one of 2 things: (1) find a reputable tuner and turn most of the exhaust treatment "off", then remove the DPF, or (2) reset the error and drive it straight to a dealership and trade it in.
If you live in an area that doesn't require emissions testing for tag renewal or registration, you can live without the DPF. Finding a good tuner will be more difficult these days, as the EPA seems to be cracking down on them. Ironically pointless, since passenger diesels account for probably 0.0001% of all vehicles on the road, and as such are not responsible for tailpipe emissions like we've been warned about.
