2AAF FUel pump
2C3D Lambda probe in front of catalytic converter, control failure

Jb4 g5 iso is updated fully up to date

Last time I filled up with 25% e85

Any ideas on the codes? I figured the 2AAF is HPFP

I'm still under CPO warranty until October.

Does anyone have any insight on why I got 2C3D?

[Mikey335]

Now in some driving this evening I've gotten 2C2D. When I get that fault I get no SES or CEL. But it takes me from map 5 to map 4.

One thing from reading that you could try is an adaptations reset or jb4 reset if that's possible. Make sure you have the latest firmware for it. Going down the line I mean it could be a bad o2 sensor on its way out. This is all googlefu. Gl, bud. Let us know how it turns out. (Strictly in regards to the lambda codes)

Adaptations reset as in...

1. During this process, never touch the brake pedal & keep the key inserted the entire time
2. Insert the key and push the start Button (all idiot lights on)
3. Press and hold gas pedal for 5 seconds
4. Without releasing the gas pedal, push the start Button
5. Release gas pedal
6. Wait a full 2 minutes for the electronics to cycle
7. Start car normally


That?

My jb4 is most updated firmware and interface versions

Nope, adaptations reset as in plug in a Cobb tune or bav tech cable and select "reset adaptations". It's a different set of adaptations.

[Mikey335]

Is there any other way to reset values without BT tool or cobb?

[Mikey335]

I've recently went to stealership and had all adaptations but my tranny reset, no changes at all.

*Note Pulls were done in 3rd gear. I drop from Map 5 to Map 4 every time only in 3rd. I can launch just from in first or second with no issues

Does this give any insight to wtf is going on?

[Eat.Sleep.Race]

my car is doing the same on Map 5 it jumps into Map4 and its only in 3rd gear as well, but my logs look fine.
