    Going to change my battery but I might not have access to vcds to do the calibration.

    My car is getting serviced in 2 weeks and if change the battery this weekend is it still safe to drive the car and etc?

    I'll of course ask the mechanic to do it when it's being serviced.

    Why not just buy the battery and get the mechanic to fit it. Then you put any liability on the garage.

    You can change the battery without any vcd stuff like previous generations.

    Whenever you unplug/plug the battery, and then try turning the car on you will get a bunch of error issues. Don't worry. Drive the car and they will go away as the car will calibrate itself.

    Whatever you do, DO NOT BUY OEM batteries! They are horrible and don't Kat more than 14-18 months. I bought mine from local car parts store and it has a 3 year warranty and tons cheaper.

    This is most likely for the cars that have stop/start function as the battery module has to be at a certain level for it to work consistently. 2015-2016 USDM cars didn't get this till 2017.

    There are other calculations going on but the two main are the stop / start and so the vehicle can work out the condition as well as charge and discharge rate for OEM feature support, such as regenerative breaking.

    Coding a “like for like“ battery type is simple, no reason not to do it other than they person completing the works not having a coding tool and not knowing what to do, in which case you should go elsewhere. If changing for a different battery, ie size, then it should be coded to avoid potential issues down the road.

    US dealership didn't do anything but change the battery in my car. Specifically asked them about it, said wasn't needed on newer cars.

    Died again about 12 months later went aftermarket, changed myself, perfectly fine. I believe the battery size is 85 or 87, nothing needed computer side and you can't physically go bigger or smaller... at least in US markets.

    Well if it works for you happy days. There is a procedure which should be completed.

    I understand that, just think it's only for 17+ cars in the US. Though the stealership price is the same.

    So got the battery changed myself, simple enough to do with my brother and no one died in the process.

    I was looking for this BEM code when I took the battery out of the box but there wasn't one. So i contacted Tayna support and this was there response.

    Me
    Hello, I bought this battery and its now fitted and car is working however my concern is that I was expecting to see the BEM code somewhere on the battery. As I've replaced my old one I want to know whats the best practice to get this coded for my car? Its for an Audi a3 8v 2013 (EO13SVA)

    Tayna
    Thank you for your enquiry.
    The manufacturers no longer put BEM codes on the majority of the batteries. Unfortunately the only way to get this coded will be to go a garage.

    Me
    Hi Jamie thanks for the response.
    So when I was choosing a suitable battery for my car using your website. It did have other manufactures of possible batteries I could have purchased. Are you advising if I was to get a Bosch battery for my car it would not have the BEM code listed on the battery anymore?

    Tayna
    No none of them do I am afraid. You would need to purchase direct from the manufacturer. This would be expensive as they wont sell single units.

    What to do if a Fitment Validation Tool requests a BEM code
    There are some Battery Validation tools that request a specific reference number to be inputted when replacing a battery. This reference is known as a BEM (Battery Energy Management) code and is on the lid near to the barcode of certain manufacturers’ batteries. It is in the form of a 9-13 digit reference, example: B 26 611 707 0UO.
    They state that this reference number is required for the validation to be completed, and unless a correct code is entered, this exercise cannot be finalised.

    THIS IS COMPLETELY FALSE.

    They are simply trying to push Customers into fitting their products only.
    If this code is requested when a battery is being validated by the use of one of these tools, then any sequence of random numbers/letters can be entered. These will not be recognised, so the Validation tool will simply move to the next step and ask for either:
    Confirmation that the replacement battery is the same technology and capacity as the one currently fitted.
    The Battery Technology and Ah Capacity to be inputted.
    Once either of the above has been done, battery validation will be completed.

    As long as the vehicle knows the size of the battery, and the serial number is changed, then all is good. Changing the serial number, even by one digit, lets the car know it needs to reset its data.
