Check engine light DPF issues

MIL light came on with
111500 The regeneration frequency of the diesel particulate filter is not ok
111600 The regeneration of the diesel particulate was aborted.
Took it into my local MB service guy who said I needed a new DPF filter for $3250....

Instead I removed it and then took the DPF and had it baked and cleaned. Unfortunately I still have the code, even after resetting I also still have poor performance and torque, but im not in a "limp" mode.

2010 ML 350 Bluetec 165k mi

No gunk around the injectors,
New air fitlers,
Fuel filter 10k ago
No exhaust leaks that I could feel.
No black smoke
Smells like exhaust when idling, but thats probably the crappy connection on the maf and turbo.
While accelerating 100% Throttle the max differential I got was 10 psi. after cleaning

Im debating to remove the DPF and tune or go to the dealer for their 205.00 diagnostic...

I had mine cleaned out and replaced the 2 sensors and has been fine so far. Knock on wood.

Did the cleaning shop gave you the before and after parameters compared to factory spec?
What is their warranty on cleaning job?
Facing $200 for diagnostics, I decided to spend $150 for (another) new generation scanner, who can troubleshoot DPF and force regeneration.
Don't buy the "XDOS\DAS\Vediamo\SCN coding\flashing " on this forum.

no parameters. Shop gave me 1 year warranty. Ended up costing me $1100 for cleaning and 2 sensors with labor.
