Battery replacement with Audi/VW Enertec battery VCDS coding: SOLVED
OK, let's get coding:
1. I got to the current BEM code in VCDS under 19-CAN Gateway -> Long Adaptation -> Channel 4 -> Battery Identification/Replacement. This code should reflect the info from the last installed battery. Just as an FYI, if the code here is different than the BEM on the old battery you know that it hadn't been applied the last time the battery was replaced.
2. I applied the BEM code in the following manner:
- (N) Part number - (11 digits) - Enter in the part number that's in big letters on the sticker on the battery. Note that the Enertec battery's part number starts with 000. This just means it can go into either a VW or Audi. Keep/use the "8K0" instead of the 000. Also, your Enertec battery MAY have an 11th character. Mine had one. My number has an H as the last/11th character. VCDS ignored it completely and left that character a space, so if your part number has the 11th and VCDS does the same thing roll with it and let it stay a space.
- (V) Vendor code - (3 digits) - in this case it's JCB for Enertec as it is actually Johnson Controls that makes the battery (who also makes several other good brands, like Interstate and Sears batteries).
- (S) Serial number (10 digits, with the first 6 as the manufacturing date of the battery and the last 4 as part of the serial number of the battery.)
This is what the string will look like: NNNNNNNNNNN VVV YYMMDDSSSS
OK, I'll use my Enertec battery swap as an example so hopefully you can follow along.
1. On my battery, the part number was 000 915 105 DH. As mentioned above, I kept the first 3 digits as 8K0 instead of the 000 on the battery. Make sure to skip the spaces between the number groups in the part number and enter in your number like this: 8K0915105DH.
2. The Enertec battery is a Johnson Control battery, so the vendor code is JCB.
3. This last one involves using a QR label reader to read the QR label on the side of the battery. Mine came out to: 205# 000 915 105 DH #0803800#588119201#15031611*205EMC3G3F00WX*=. That's a lot of gobbledygook. The first part we need is the first 6 numbers after the 4th #. In my case, that's 150316. That's the date my battery was manufactured - March 16th, 2015. So, the first 6 numbers of our serial number is 150316. Even if you don't enter in all of your battery info you should at LEAST enter in this mfg. date into VCDS so your car knows the age of your battery. The next part is the a few characters of the last batch of numbers. From what I've seen on other folks batteries and what they entered as well as compared my own you need the 10th thru the 13th characters the finish out the serial number. In my case, that was F00W. You can disregard the rest. This completes the serial number, which is your equivalent of: 150316F00W.
4. I tested all of the above and VCDS was happy. Now save it and you are done!
Before anyone asks me, no, I do not know how to input other batteries that are not sold by an Audi dealer (Sears, Interstate, etc.). I pieced the above info together with tidbits of a few other threads on the net as well as my own experimentation and observation and trial and error. If you are lucky enough to get one with a BEM sticker on it your work is done for you.
As always, YMMV.....
