Maybe those invoke only if the car has flagged the battery as needing replacement though. Some have said some car functions might operate in a lower power mode when the battery gets old, and recoding resets those tunings. I find it crazy that the charging electronics cannot realize the current state of the battery and address car functionality accordingly. Once steps 7 & 8 are complete return back to the main VCDS home screen. If any faults have flagged up select Clear DTC’s it will then automatically auto scan again. As the new battery was same (or higher) capacity than the old one I basically recoded it with the original battery info. 82 kWh battery (77 kWh net usable) 0-60 km/h (37 mph) in 3.
#Vcds battery coding code#
The car continually thinks it has a flat battery. Select Battery coding for battery manager The procedure codes new battery data into Energy Management controller. We are able provide you with the original manufacturers security code required to activate. Not an OEM battery so doesn't have an Audi part no to code in via VAG-COM. (This will now have saved all of your original coding) 8. As per my posts in the A8 forum, I replaced the battery on my car. I've yet to find anything that conclusively presents the problems with not recoding. Once scan is complete select save and fill in all the details. Installation is certainly a DIY, as is the coding if you have a VAG-COM. I'm more concerned about the the typical shelf time for these various vendors.

Question is, do I really need to code the battery? I've read through 10+ posts and there seems to be an even split between people claiming that the new battery must be purchased from Audi and coded, and those saying that we can just purchase the proper battery from Autozone and swap out the old one.ĭifferent sized batteries depending on your PR code. Sears said they could replace and "register" the battery for $280.
Called Audi to inquire about replacing the battery, they quoted me a ridiculous $600 (apparently it takes them 2.5 hours of labor to replace and code a battery).ĪutoZone charges $150, but can't code it. New battery (the same one as Gups) fitted and I think coded correctly but am getting the following VCDS fault, along with the battery light coming back on after 10 secs Address 61: Battery Regul. I figure recharging the battery is out of the question. Now, I need to jump it every time I drive. It took two jumper boxes (battery and under the hood) to get the car running. The car was running perfectly fine before leaving, when I got back, the battery was completely dead. Since Bosch batteries are made by Varta it should be a simple case of using the BEM code off the Varta equivalent to write into the BMS.Long story short, left my car in covered storage for 3 months, was in a rush and forgot to disconnect the battery before flying home (my fault, I know). The battery may or may not have a BEM sticker on it (Tayna told me that it is unlikely to have one) and it is this BEM code that you need to put in via VCDS to let the Battery management system know what type and capacity of 'reservoir' it has to fill up and draw from. This chart is for Automotive, Marine and Motorcycle batteries, but may apply to other types. Date code is engraved or hot stamped into the battery case somewhere. Some more information that might be useful to anyone doing a similar thing. Depends on what country you buy it in what type of date code they use.
