Hello,
On the Golf 5 1.4 TSI BLG, the intake manifold flap potentiometer is G336.
After replacing it, the learned values need to be reset and the intake manifold flap system adapted.
VCDS may be able to perform this through 01-Engine → Basic Settings, depending on the ECU software version.
However, VCDS cannot flash or reprogram the ECU firmware. If Erwin (siehe
Fehlerdatenbank) specifically requires a software update, ODIS or another compatible programming tool is needed.
Could you post the ECU part number and software version from your VCDS Auto-Scan? That would help identify the correct adaptation procedure.
