2882 is back, Fuel Trim Bank 2

[Reckless]

Quick Synopsis:

2882/2883 Came up at the End of May - Found out there were mice lodged in the DISA



So I:
Rebuilt the DISA with the GAS kit
Cleaned MAF
Cleaned ICV
Replaced Lower intake boot
Cleaned Throttle Body

Fast forward ~10k miles and 3 months to last night and SES kicks on again. 2882 this time and no 2883 to come with. Any ideas on why this would be. The only other thing I could replace would be the CCV but I would think both codes would kick for that problem.

Now I am thinking Passenger side O2 possibility because of the lone code.

Lambda Adaptations are +/- 3.91 so close to normal range and noticing slight lower MPG but not terrible. I cleared the code and getting ready to change the oil today and monitor the fuel trims.

Any thoughts, ideas, experiences?

That is insane. holy shit.

What did the code reader say the actual fault was. Not familiar with 2882.

GS3 + TT4

- Found out there were mice lodged in the DISA

WTF? That's just freaky. Was your disa missing the small cover?

[Reckless]

not missing the cover, just had to be removed to clean the mice out.

Ok... So the mice just crawled in there and got stuck. Or were the mice possibly bred, in the disa, to aide in eliminating the 4k rpm dip perhaps?

This is unreal.

Made me think of the joke...

How many mice does it take to screw in a lightbulb....at least two.

The thought has crossed my mind that they were in fact the ones operating the DISA valve, once the engine hits a rev that is too loud for their tiny ears, they start moving which opens the Valve. I didn't perform the PM mice replacement, so I guess they just fried up after a few years of hard driving.

On a more real note, they were eating the flame retardant mat under the hood and that crap is everywhere. I was bleeding the fuel rail the other day and I am still finding pieces of that stuff everywhere....

after fuel filter, fuel pump and new plugs, car feels like it i running like new. No codes as of yet, but I fully expect to still be chasing lean codes

Codes are back, only bank 2. Next will be Vanos and new VCG. I wish I could solve this problem, yet it is making me do maintenance instead of the mods I want. Win win win in the long run, but more frustration in the forefront. Will update after the holidays with hopefully good news and ability to move forward.
