Hi all, Happy New Year!

Bit of a strange one. A 2013 (63) MkIII Octavia, I today replaced the original 12 year old OEM EFB (stop / start) battery for a new one for a friend.

The new battery is branded Audura (from Euro Car Parts), but without a BEM (Battery Energy Management) code. As a result I was hoping to follow the common advice of changing the 10-digit serial number from 1111111111 to 1111111112.

Before that I first changed the Ah setting from 59Ah to 70Ah, which was accepted.

The battery type was already EFB, and as the replacement was also EFB, I left this unchanged.

I left the battery manufacturer as JCB as I don’t know the code for Audura.

However, when trying to update the serial number VCDS told me that it needed to include an alphanumeric character. I tried a few different configurations including both letters and numbers, but the same error appeared each time I clicked ‘Do it!’.

Any ideas?

I’m hoping the successful change of the Ah will be enough to ‘tell’ the car a new battery is fitted…

From memory I inputted the following: -

I entered the new battery capacity ( up from 049 to 060 (AH's)), space, UNK ( for the battery manufacturer ), space, and added 1 to the serial number ( ten digits ) and confirmed.
Eg:- 060 UNK 1111111112

This was with OBDeleven.

Thanks. AG Falco

Quick thoughts.

Is the VCDS program up to date for the car.

Laptop battery to low.

Have you checked car battery voltage at connections to confirm as good.
