So I have a 2009 BMW 328I, has the N52KP, black top, no disa, completely stock, but I've been experiencing sluggish and slow acceleration, like I'm talking about an average of 12.7 second 0-60s, car is up to date on maintenance and no cel, but I did get 2 ghost codes in inpa, 2AA8 and 2AA9, which is weird because one of these codes involves disa, which i don't have, but the other one is vanos, so I took a look at values of disa while the car was warmed up idling, here's a picture. What should I do? Replace VANOS?

It has one disa.

It does? Are you sure because I looked and I swear I couldn't find it

I just check now, the car had a 330i tune so both 2AA8 and 2AA9 are faulty ghost codes, so technically i have no codes at all, but when I check my cats, header 1 warmed up was 427 pre cat and 350 post cat, for the other header it was 300 pre cat and 350 post cat. Any idea if it could be a bad cat?

AFR?

LTFT?

STFT?

Is trans shifting as it should? Go to manual mode, and start in first!

Also, do a controlled highway test of mpg, say 50 miles at 60 mph. Fill before test and fill immediately after.

i don't have [please clarify this] ...

Both the 2AA8 & 2AA9 Codes are DISA, one for each Servomotor; 8 is for Servomotor 1 & 9 is for Servomotor 2. Here
are Links to BMW Fault Code Lookup Info Sheets for each:

Your VANOS Cam Angles & Deviation from Target Values (Sollwert) are fine. NO VANOS issue.

I would suggest viewing & attaching ScreenPrint of Fault Code with Freeze Frame Data for EACH 2AA8 & 2AA9.
Here is the INPA Menu Sequence/ Path to view that data:
INPA > MSV80 DME > F4 > F1 > F3 Fault Memory with Freeze Frame Data

I don't have DISA on my 3/2007 build 328xi. Attached is a ScreenPrint of the DISA Activation Screen:
INPA > MSV80 > F6 Activations > F1 Group 1 > Shft+F6 Activation DISA
My screen shows the default value for NO DISA valves & indicates NEITHER is available for activation. Both are Closed (33%)

Either you have DISA & neither valve is functional, OR the DME coding is for DISA but you have NO valves.
Please attach ScreenPrint of YOUR INPA "Shft+F6 Activation DISA" Screen.

I'll check my AFRS and Fuel Trims thanks!

Yeah I think I just have no valves but those codes are popping up due to me putting a 330i tune making it trying to trigger disas

[Dpac07]

These normal?
