Replacing your car battery in a VW vehicle isn’t just a simple swap; it often requires coding the new battery using VCDS (VAG-COM Diagnostic System) to ensure optimal performance and longevity. This process informs your car’s Battery Management System (BMS) about the new battery’s specifications, allowing it to charge and manage power effectively.
Recently, I went through this process myself when replacing the original battery in my VW. The old battery, a VAO with BEM sticker 000915105DL VAO 300425P18Z, presented an interesting challenge. The existing VCDS coding didn’t perfectly match the battery details, possibly due to issues with reading the VAO/VA0 code during previous service, or perhaps the coding was simply never updated with the battery change. Surprisingly, the removed battery had a date code of 9/20, suggesting a rather short lifespan.
Referencing a helpful chart online, I confirmed that the battery part number indicated a 110Ah capacity. Using VCDS, I entered the following coding:
000915105DL VA0 930920K9G6
Upon testing, VCDS accepted and saved this value.
However, a point of concern remained. The BEM label lacked a directly valid Battery Code for VCDS. Valid codes typically include 5DO (Boading), TU3 (Excide), MLA (Moll), JCB (JCI), VA0 (Varta), and UM5 (Akuma). I opted for VA0 as it was the closest match to the original battery’s branding, and the replacement battery was an Audi genuine part, aligning with the VA0 code.
Currently, this coding is in place, and everything seems to be functioning correctly. However, I’m still open to insights and suggestions, particularly regarding the CCL code and whether the chosen coding is entirely accurate. If anyone spots any errors or has further recommendations, your input would be greatly appreciated.
