Had a CBU cleaning done by my local last fall. Car threw an injector zero adaption code shortly after. Shop replaced three fuel injectors under extended warranty (convinced the warranty company to replace one full bank). Threw more codes. Took it back and showed them the BMW recommendation to upgrade the software before replacing injectors. 500 miles later throws 3 cylinder and injector codes. Reset and 575 miles later throw the same three codes plus the Air Mass Sensor (using foxwell):

3FF1 DDE Air Mass Sensor
4592 Smooth running controller, cyl 4
4593 "", cyl 2
4B05 Zero quantity adaption, cyl 4

I'm about to cave and sell this car. What would I look for next? Help!

Oh and an unrelated AUC sensor code keeps popping up.

Have proper adaptation resets been done along with proper re-adaptation procedures. Injectors codec? Latest software loaded?

Frankly not sure. Assumed my shop did that when they presumably updated to the latest software as I requested. But maybe I shouldn't assume all that. Is that something I an do with the Foxwell? Admittedly I read about the re-adaptation procedures in some searching, but didn't really follow what is needed to do it.

[octalon7]

Actually now that I look at the records, the exact same codes were the ones I reset before, so it's consistently throwing these 4 DDE codes every 500-700 miles after the CBU and injectors replaced.

Car runs fine, smooth. Gas mileage has improved since all that work was done.

I would suggest to see someone knowledgeable. May be your shop is good but sometimes even dealers don’t know what to do. It’s sad. I would update to latest software, reset all adaptations (air, exhaust pressure, Mean Quantity, increment wheel) and run through zero quantity re-adaptation.

Well this wasn't a dealer, to be clear. It was an indy who claims to work on the diesels a bit. I do have another couple shops I have used, but rather than continue to risk it, if I'm not mistaken with my research, I think I can do the resets and re-adaptation with the Foxwell tool? I'm just not finding clear instructions. Do I just go in and reset them all or sequence them? Car on or off? Do I need to be driving first to reset any, etc? I will continue to search, but most of the posts I read are people advising someone to reset but haven't run across procedures yet.

If I'm not mistaken you cant do all the resets with the foxwell... you can do a few from what I have found

I think I read you can do the injector resets? I haven't found the menus yet though. Are the resets as simple as clearing codes? Just reset and then drive?

I had a similar experience after I did CBU cleaning. I was able to use Foxwell to reset and clear injector adaptation. I also was getting mass air code which I could not get to stop recurring. After 2 months and many code clearing the error continued upon every car restart. Finally, when I went to dealer to get Driver Side airbag recall complete I got the shop to reset mass air adaptation. Code cleared and no more recurrence or check light for mass air.

Do you recall the exact mass air sensor code you were getting? Very curious to know. Thanks.

Thank you, that's great to know. Do you recall where you reset/cleared the injector adaptation? Just reset and drive?

I kept getting 4592/4593 errors after injector replacement / cbu cleaning etc.

Resetting increment wheel adaptation fixed it.

Great, thanks. Sounds like I have a good list of adaptations to try to reset, now just have to see which ones I can do myself.

I'm not sure what the foxwell can or cannot do but you can send a PM to bimmergeeks, a vendor that can help you download software that can reset all adaptations (and do many other things). They also sell the cable you'll need.

Thanks, that's good to know. I don't think I have a windows laptop that works any more these days. Going to explore more with the Foxwell, but my shop should also be able to do all this. Just need to find time to head over there and ensure they are resetting the right adaptations.

Wow, perfect, thank you! I read through it quickly, when I get a chance I will pull out all the adaptations you can perform and highlight them here for others that might search the forum.

[jjbaldasano]

In response to previous question asking what mass air code I was getting, it was 3FC0.

[octalon7]

Here's the list of adaptation/reset/adjustment functions (there are others too on that list) the Foxwell says it can handle:

Adaptations:
Drive - Clear adaptation
Drive - Clear mixture adaptation
Drive - Clutch adaptation
Drive - Display and reset adaptation values
Drive - EGR adaptation
Drive - Engine control: Mean quantity adaptation
Drive - Quantity mean-value adaptation
Drive - Read/Clear adaptations
Drive - Reset the adaption of the electric fuel pump
Drive - Read and delete Swirl flap adaptation
Drive - Transmission adaptation

Reset:
Drive - CAS reset
Drive - Reset CBS Condition Based Service
Body - Reset internal ELV fault counter
Drive - Reset learning functions
Drive - Reset pressure control
Drive - Reset LVS values

Adjustment:
Drive - Adjust injector
Chassis - Adjustment, steering-angle sensor
Chassis - Adjustment,DSC unit(4-cyl.)
Drive - CO adjustment
Drive - Data adjustment,mechatronics
Drive - Fuel consumption display adjustment
Drive - Injector rate adjustment
Drive - Mechatronics adjustment
Drive - Minimum stroke adjustment
Drive - Oil adjustment
Drive - Oil-level adjustment

Frankly not the greatest descriptions, but this list is quite helpful. Any thoughts on which ones I should be looking for in the menus?

[charlie fairmont]

I would start with this one:

Drive - Engine control: Mean quantity adaptation

[octalon7]

Thanks, that is the one I did this morning. Just cleared the SES codes first and then ran that adaptation. Car off, ignition on.

[octalon7]

Well, after 413 miles after using the Foxwell to "reset" the adaptation for the mean quantity, codes came back.

Same 3:
4592
4593
3FF1

And added a few different ones:

4D16 (had this one and off before carbon cleaning)
459C
4D35

Reached out on the PNW forum to see if anyone has a tool to help try a few more adaptations. Any other thoughts?
