Got a VAG COM today. Pulled Codes....can anyone help with these?
3 of the codes point to the EVAP system. I think there is prob a loose or cracked hose...not too concerned with it.
But the one I'm a little concerned with is a
Bank 1 Mixture Adaptation: System to lean.
I had a MAF code "high input," but since then I've replace the MAF and that one is gone. I was hoping / thinking that a new MAF would get the lean code too...but now I'm looking for some direction on it.
Also if anyone has the exact proceedure for the BOSE radio mod I'd be greatfull. I'm new to the VAG COM so a true Step by Step would be great until I'm accostom to moving around in the system.
Thanks all. If anyone is in the Fox Vally WI area....Scans will cost you a 6 pack of Leinies.

Code should be P1136 or P1128
From Bently Pub.
P1128 Bank 1, mixture adaptation (mult.) System too lean 4
-Check Mass Air Flow (MAF) sensor
-Check oxygen sensor
-Check fuel injectors
P1136 Bank 1, mixture adaptation (add.) System too lean 4
Road test vehicle (fuel in oil)
P1128 Bank 1, mixture adaptation (mult.) System too lean 4
-Check Mass Air Flow (MAF) sensor
-Check oxygen sensor

check and replace all vacuum lines that are cracked or old...
vacuum leaks will throw off the MAF. Check especailly the vacuum line leading to the combi valve. Also check the breather lines under the intake manifold. There is a breather down there that splits often. It is not easy to get to. You will have to unbolt and move some stuff out of the way. Dealers often use a smoke machine to find these sort of leaks.

Actual codes
4 Faults Found:
17884 - EVAP Leak Detection Pump: Insufficient Vacuum
P1476 - 35-00 - -
17544 - Fuel Trim: Bank 1 (Add): System too Lean
P1136 - 35-00 - -
16825 - EVAP Emission Control Sys: Incorrect Flow
P0441 - 35-00 - -
17877 - EVAP Canister Solenoid Valve 2 (N115): Open Circuit
P1469 - 35-10 - - - Intermittent
Readiness: 0000 0100
The codes were cleared after the MAF was replaced by my local shop. These have occured since then.
