After changing the engine battery of my Audi A6 2.4 tiptronic 2000 model I realised that the claster is not working any more, temperature gauge, petrol, kilometer counter etc not working any more, please assist me on how I can reset the system.
You must go to your agent VAG so that it uses bag VAG COM to reset the system.
To avoid the troubles, it is necessary to connect a pile of 9 V in lights cigar before changing the battery.
It is too late, but know it to you for the next time
