I have also problems with regen in cold, on my 2010 D13, the reason i came here in my desperation looking for help. Did you check the aftertretment shutt off valve, you should have same on 09 MP7, only EPA 2010 has AHI . left side behind the fuel filter assembly,, it has 3 fuel lines and 2 sensors. Not familiar with Macks, but are very similar with Volvo D13 ; this photo i found looks identical with mine, here a photo i have on my phone.
