Hello,

When the value of the dpf is higher than 200, the autel won't let you regen the dpf,
because it is to contaminated for a regen. But I have maybe good news. My Mercedes
W204 2011 was in save mode (max 3000rpm) because of the dpf being full, which
wasn't true. First of all, check if your dpf sensor isn't broken before dissasembling your
dpf to let it clean. My autel was reading a value of 400, which is the max dpf value.
When that is the case, it's most likely your dpf sensor (Bosch partNo, 0 281 002 924). I
hope I've helped you with this. Kind regards.
