HELP


When the message center displays "cleaning exhaust filter" I press OK and hell breaks loose the trucks starts shuddering, surging, bucking and the engine rattles like my 02 Dodge CDT.

I have taken it to the dealer and of course they could not find any codes:icon_mad::icon_mad::icon_mad: so I took the truck back over the weekend to see if the truck would do it again---- well of course it did it again...wanna bet they cant find codes again..:icon_mad::icon_mad:

Ideas Please Help---

Thanks Cory--PM Sent
I cant believe depressing the "OK" button would cause the issue-- But I tell you when it has happened-- as I stated above it feels like all hell is breaking loose.

Cory has jumped in to help - Thanks Cory. I feel the dealer is doing what they can- I 'm not certain they know which way to turn at this point
Update

On August 29th I made an appointment for today August 31st. I left the truck at 0700 this morning- I called at 1600 hrs and asked if they knew anything about the truck. I was advised they did not look it today and asked if I could leave it overnight- they would look at tomorrow - - I replied- I need the truck Friday

Update

Sept 1 the dealer preformed an "extensive road test- determined the DPF was reading 104% on the start of the regen then dropped within 2 seconds to 24 %. They re calibrated the brain box and cleaned the DPF the old fashioned way" their words not mine. The service manager also said the mechanic experienced the full gambit of what I was describing

At first blush the truck seems to shift smoother-- this weekend will be the test.... I will let everyone know what happens after this weekend...hopefully this has taken care of the issue
Update

After 500 miles without any issues that I described above-I believe the re-calibration solved my issues.

Thank you Fremont Ford and Cory with Ford Customer Service for your help.
