Regeneration Frequency Issue: MAF Poll

[Blackpowder]

I would assume so.

Thanks. I assumed this also, but could not find any linkage of these numbers on the internet.

Beware. I’ve seen eBay sellers with photos of the German marked part but mistakenly listing it as the 68444077AA.

Has anyone gotten the updated MAF yet and seen any positive results ? Just curious if this actually is the “Wonder Drug”.

@scdo Had the new MAF installed by dealer but no improvement.

Automatic Regen too often

Thanks for the update. Do you have any tips regarding how to start the arbitration process? You mentioned it is a free process; I would like to pursue a similar action, if possible, but I can't find information that explains how the process works or how to get started. I live in CA so the laws...

Seems we have at least 3 separate threads on this issue.

Yep, it did not help at all.

Did they do the MAF reset procedure @mbarber84 posted previously? If not, it may be going off the old lookup tables.

I am going to try to do that drive sequence today and see if it’ll reset even with the “bad” MAF. Hoping it will revert like it was new and take a while to learn the bad behavior.

You know, I’m not sure but STAR advised them the fix didn’t work. It couldn’t hurt for me to try that procedure myself.

Is the maf reset procedure possible by us with alfaobd/bypass?

.... Asking because I have the "tick" which is awaiting parts but also mine is regening about every ~350mi when it used to regen only at the 24hr mark... Honestly not sure what caused the change.. Like others I thought I caused it by not installing the correct filter but the correct one has been in for almost 10k now and no changing frequency.
Could my tick be contributing to the regens frequency?.... Unsure.
Edit: I have the German MAF in mine. It's never been replaced.

See page two of the doc previously posted - looks straight forward.

no regen issues, every 24 hours except one time in 29,000 miles.

German sensor with an S&B intake and the oiled filter.

Some people are just lucky I guess.

Cleaned my MAF(not dirty) and MAP (very dirty) and did the maf relearn drive cycles. The throttle response is noticeably better and fuel economy for a loop I'm quite familiar with is much better... Soo fingers crossed this might have a positive effect on the emissions/regen logic once it catches up to the changes.

My MAP was just as bad and I cleaned & didn’t have a regen for 10 days , prior was every day !
Did you replace sensors with German or Chinese?

How did you clean them?

MAF just some BW contact cleaner. MAP non-chlorinated brake cleaner. Soot was thiccc

Did not replace either sensor, just cleaned. Both are ze-German

How did you clean them?

I only cleaned the MAP with alcohol until no more black came off q tips. Did not clean sensors in air box top. They were perfectly clean & clear.
