There are many many different types of codings available on Volkswagens and Audi control modules. Especially on the MQB platform, the lighting options are almost endless and most all of it is in German so be very careful what you are changing. Control module coding for module replacement typically you will match the original coding and you are good to go. For coding options for your particular make and model you will want to find a forum listing out all the common and available mods for your particular platform. Window changes, exterior / interior lighting changes, alarm horn signal changes, door autolock changes etc. These coding adaptations or long coding changes can easily be changed with VagCom VCDS or OBD11. Just make sure you write down your original coding so you can revert back easily if needed. I've fixed more than a few customers cars coding that got a little too far down the rabbit hole with their OBD11 and major functions like headlights or brake lights stopped working because they had a software coding change that didn't match the hardware and they couldn't figure out how to revert back.
same fault code customer dropped car off - new n75 valve solenoid - new turbo - service - not boosting ? What could be the issue 2015 2.0 gtd Thank you
Check the vacuum supply to the N75 valve, check the vacuum lines for cracks or breaks. Smoke test the entire system for boost leaks. Cracked charge pipe, cracked intercooler, leaking boost hoses etc. Monitor boost spec vs actual while test driving. Good luck

Thanks for the tip matt do you guys do coding for vw? A coding video would be great
