Hello,

I'm having a problem with a VCDS unlock code for the headlight range adjustment. The code provided by VCDS is "61378" for an Audi A4 B8 Avant S-Line 1.8 TFSI, manufactured in 2008.
This code is incorrect and will not be accepted. After researching online, it appears that this code is also identified as being wrong.
The unlock code 61378 is not correct for the headlight range adjustment (LWR) in many vehicles. This is a generic code that varies depending on the vehicle model, year of manufacture, and specific equipment. To find the correct code, you must specifically identify your vehicle to determine the appropriate unlock code.

I have restarted the system multiple times, and I have tried to automatically determine the vehicle type using VCDS, as well as manually entering it. This has not yielded any success, and the code retrieved by VCDS remains at "61378".

Can someone help me with this and provide me with the correct code for it?

Thank you in advance for your efforts.

Best regards,
Enrico Ochschim.

Hi,

Please Autoscan.

Sure, here is the translation of the text from German to English:

"LG" translates to "Best regards" or "Sincerely" in English. It is a common abbreviation used at the end of emails and letters.

The automatic scan has been performed multiple times. As I mentioned in my message, neither manually entering the vehicle information nor using the automatic scan leads to a different result.

Hello,
We will perform another vehicle scan as soon as possible and post the data obtained from that specific vehicle here.
