How to Recode and Install a Battery on an Audi S4

There are lots of questions around if you need to actually code the battery when replacing it on newer Audi models. In this video we show you how to perform that coding on a B8.5 Audi S4. And show you where the battery is on that model.

[@nicoboiardo3612]

You're absolutely correct but a lot of people don't know and it does work cuz I'm a mechanic too if you have a power source plug it into the cigarette lighter make sure you have a power jump box of boost one that actually could charge to a lot of connections to connect the power source to the two terminals of the jump box and then disconnect your battery and you won't lose any of your data connected back you won't even have to program it I do it all the time

[@Particle_Accelerator_Repairman]

They could just as easily have a reset function, like the oil change and Inspection reset. The system just needs to know that the part is new. The fact that they look for part#, vendor code, and serial # is to reinforce the idea that you must have a genuine Audi part. This will work on many folks who do not know better, and go to the dealer and drop $350 on a batt that can be had for $150. I have a family member who recently went to Benz dealer for her car and way, way overpaid for a battery. And the dealer reinforced the idea with her, that you should never use a 3rd party batt in your car, " because it will cause so many problems" .... Marketing BS. Knowledge is power.

[@rkan2]

ShopDAP should do a collab with Louis on right to repair :)

[@wrxkyle]

are you sure on this and that the bem code contains no information as to the battery capacity and type? (agm vs we cell, which have different voltages, and affects how much charge the car sees it needs to give...

[@Particle_Accelerator_Repairman]

@@wrxkyle That's a very fair point. I guess I'm thinking that you would only put an AGM, but you could do a traditional batt. and that info would indeed matter.

[@DurkoppFordertechnic]

@@wrxkyle my car needs the part number because it contains the correct AH of the battery. I replaced my battery recently and the car wouldn't charge it past 80%. I changed the serial number in Vcds by 1 digit and the car then knew it was a new battery and allowed it to charge to 100%. The new battery would have failed prematurely as it wasn't fully charging.

Tbh they should've made batteries last the life of the cars by now. Even Tesla is only now starting to do it for the 12V system. Lead acid technology is as old as cars are. A typical gas car could do just fine with some 20Ah lithium pack. I'm waiting to see what type of battery Tesla is going to use for functionality in colder climates.

[@300DBenz]

Requiring a serial number to change a battery is stupid, the car already knows how much voltage the alternator outputs, days and mileage since last battery service, all it needs is a “Reset Battery Life” option in the same service menu as the oil change and brake pad resets.

[@bootneylee9802]

I fully agree with this. 👍

[@jeebsy718]

You can just make a serial number up. So long as the car sees a new serial number it will recognise it as a different battery. Common advice is to just change the last digit. A option in the service menu would be convenient though.

[@M0N33R]

My 2011 VW CC wasn't programmed from the factory even. Later the battery was replaced for a genuine (Varta) & the dealership didn't re-program. I did it myself via VCDS, and it was much simpler than this OBD11, don't need these codes, except one correlating to battery capacity if I remember correctly.

[@jmrtinez69]

[@yangzhang2597]

Guys, I changed the battery on my 2012 Audi A6 without reprograming the code, which was years ago. The battery works fine and still going great! I got the battery from Costco for about $150. I don't think the coding does anything other than to scare you enough so that you pay the dealer $450 to do it. As an electrical engineer, I measured the charging voltage during charge and the end of charge. There is little Audi can do to screw up a lead-acid battery.

I'm from Mexico and I just installed a new battery in my Leon Mk3. The battery had no BEM code, but the adaptation battery only asked for Ah capacity, vendor and serial number. I changed the original efb battery for a agm battery. By the way, I changed the battery 'cause it had almost 4 years. It worked fine but the midtronics says replace battery. I prefer to replace battery before it fails.

[@jjojo2004]

Battey needs to be coded because based on the voltage of the battery, the alternator will ramp up charging as the battery gets older? WHY is the car not smart enough to read the new battery and figure out the new battery has higher voltage on its own?? 🤔🤔🤔

I will try this obd2 that you using. You only need to pay for that device then nothing more? Also I just want to Add. I have 2013 audi A4. The first 3 years I swapped the battery without registering it. I used autozone battery agm. They most expensive one they have $250. Believe it or not 6 years still running. After 6 years still tested good but I replaced it anyways. I just found that battery only last 3-5 years so I replaced mine eventhough still running good just to have peace of mind. Now I just need to figure out how to register autozone battery. It lasted 6 years the last time without register so I guess I’m good hopefully

Wonder if I could get your professional opinion. The battery in my A7 died suddenly, no slow decay, just one day wouldn't turn on and was sitting at basically 0V. After some research and decidedly not wanting to spend $400 on a battery recode, I decided to hook the car up to a charger and then hot swapped the battery while the system was running from the charger. I did this in case Audi would notice and acknowledge the disconnecting of the old battery and potentially stop me from driving with an non-official replacement; just being overly cautious. I do however have an OBD11 but did not know I could recode it myself, do you recommend this now a few thousand miles after the initial replacement?
