My A6 C7 2012 Avant 3.0 TDI 245hp wouldnt start the other day. I charged the car and drove in it for some time and next day same problem. I tested the battery with a tester i got, 123Amps on it.. then let it charge for 24 hours, tested battery again 234Amps. So i bought a new battery, old one was a original battery with 950Amps 105A and new one A6 (C7 Platform) Discussion - Battery Location - Question: where is the battery located on a 2016 A6? Called the dealer, and they said underneath the driver's seat. Apologies if this has been answered before - did a search and didn't see anything.

He does the replacement by connecting a fully charged battery to the battery posts under the hood with a set of booster cables (the car is not running). He then disconnects the old battery in the trunk, installs and connects the new battery and disconnects the booster cable. The engines of the Audi A6 listed above have a Start-Stop system, and in this case, this means that we must use batteries produced in AGM technology. Matching batteries have dimensions 353x175x190 mm. The parameters of these batteries are at least 95 Ah of a capacity and 850 A CCA (Cold Cranking Amps). Have had dealings before with Tayna in the past and have found their prices and service spot on. Probably going to go down the route of replacing the battery (mechanic mate of mine check the alternator output and all good there) if I'm being honest with a Varta or a Bosch. O98Ssc.
