Our Jeep Grand Cherokee 2015 has problems with its exhaust filter. The error says we should drive safely at highway speeds to remedy but even after driving a few hours, it does not recover. It is stuck at 3rd gear (I believe this is called limp mode). Previously we had the same problem and a mechanic fixed it with an OBD-II dongle and some expensive software.
This time we bought a Wi-Fi ELM327 OBD-II dongle and connected with some free software. The error code was P2463. Last time the mechanic solved our problem with forcing the DPF regeneration. Is there a way we can do this on our own? I can't find any working solution on the internet.
Thank you for any help.
