Thanks for asking your question. I will try and help you out.

Code 3246 is defined as a dpf outlet temp fault. I have seen this many times. You most likely have a faulty DPF outlet temp sensor. As long as this code is active the engine will not compete a regen.

Please reply back if you need more help or have more questions. I am happy to assist.
