At what point in time did it become necessary to reprogram the charge rate on an Audi car when replacing the battery and is it this procedure required on a 2011 Audi A3?

Ian Jackson says:

I bought a dashcam and an external battery for my 2019 Golf R. When direct connecting to the fuse panel I would assume I need to disconnect the cars battery first when dealing with the fuse panel? Will I need to recode the car if I disconnect the battery?

Massive battery! Thank for the video.

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.

All about money.

Andrew Schaerf says:

Mechanics: changing a battery is so easy!

German engineer: hold mein schnapps.

Andy M. says:

thank you for this, was wondering where to find the setting in OBD 11 to change it, one question though, do we do this before we set the car slightly on fire? is being slightly on fire step one of this process?

Giovanni D. Puglisi says:

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 have to have an Gen. 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.

My new battery didn't come with that sticker :

Gplus sucks big says:

So if the old battery wasn't "significantly degraded" why change it? Lol

Todd Fisher says:

That’s so rediculous, it’s a battery! Why does that need so much work.

D3ADK says:

Do MQB VWs need to be coded too?

888red says:

Does this apply to older Audis like the B7 A4? Thank you!

Sam Eftek says:

Is this procedure same for 2014 TDI Passat? Nice video

Joshua Alvarez says:

Solid Scotty K moment 0:36 gave me a good laugh.
