Hello everybody,
I've recently bought my 4th Passat, this time my choice landed on a V6 AKN engine(4Motion), The guy before me had it swapped, from automatic to manual transmission, but with no changes on the ECU/TCM codings, as i first step, I unplugged the TCM, then recoded ECU to manual (00006), but for 2 weeks now, i still can not get rid of ABS/ESP lights and i'm having the persisting fault codes (Probably because the wires/relays somewhere need to be cut/changed):

VCDS Version: 12.12.1

Address 01: Engine Labels: 3B1-907-401.lbl
Part No: 3B1 907 401 B
Component: 2.5l/4VTEDC G000AG D0
Coding: 03011
Shop #: WSC 00028
VCID: 1D312F9D97C9BDF69FF-4A9C
01 Fault found:
18034 - Powertrain Data Bus
P1626 - 35-00 - Missing Message from TCU
ABS/ESP:
18055 - Check Coding of ECUs on Powertrain Data Bus
P1647 - 35-00 - Implausible Signal

I would appreciate any help, because i'm really lost, and not happy at all with the car of my dreams.:banghead::mad::(:bowdown::cry:

Hi, I have the same situation here, Engine code AKN, but FWD, when I recode Ecu to manual trans, car doesnt start but ABS lights are off, when I recode to Auto trans, engine starts but abs lights come back, and what I see and hear is Fuel pump is making a clicking sound when Ecu recoded to Manual trans. I n another forum I got answered from an specialist that says I must change the fuel pump from manual trans too, am very messed up, dont know, I also reflashed ecu with several flash files, now car is showing SG in the VCDS not AG, but result is the same.
Must have something to cheat the fuel pump to work in Manual trans coding...
