helped a friend out with getting a replacment ECU for his jetta after the original one failed. my problem is the ECU will not let me recode it from auto to manual with VCDS. does anyone know if its possible to edit the binary to make it a manual ECU? i cannot find an original manual file for it anywhere. this is all in an early 2002 jetta VR6. The ECU part number 021906018S. here is the factory file im working with.
From the VCDS lable file, for that PN ECU,
021-906-018-AFP

; Coding

C00,Engine (J220) Coding
C01,000?x: CAN-Databus
C02,+1 = Brake Electronics (ABS)
C03,+2 = Airbag
C04,000x?: Transmission
C05,1 = Manual Transmission
C06,3 = Automatic Transmission
;
So the ECU coding is "00031" for MT, or "00033" for AT. Same ECU PN for both transmissions.
