The turbo speed fluctuates between 38-56,000rpm when it tries to regen. When the engine fan kicks on the regen aborts. There's no codes.

watch my video on a regen process. Watch the DPF temps and see if they climb once the Doser turns on. If there is something wrong with the doser injector (dirty, clogged, etc.) and the temps do not rise at the correct rate then it will cancel for safety reasons.

An exhaust leak in the flex pipe or other place can cause the temps not to get up to par too.. or the turbo can be worn out, or engine have a CAC or other boost/exhaust leak and cause it to cancel.. but otherwise still be healthy enough to run the engine just fine.
