But most 2022 Audi E TRON SUV s made since 2000 have an electronic throttle body and disconnecting the battery without providing a power backup can cause problems. Late-model cars and multiple computers and specialty modules can โforgetโ their calibration settings if you simply disconnect the old battery and slap in a new one.Future versions of the Audi e-tron 55 quattro** will be able to drive for up to 436 kilometers (270.9 mi) on a full battery charge (WLTP cycle), which is an additional 25 kilometers (15.5 mi) over its previous capability. Thanks to a new type of wheel brake, the developers have achieved further reductions in what is known as residual brake torque.
Uncovering the 12volt battery (to install extension) As I've read (with surprise) about the possibility of being stranded by a discharged 12v battery (and not being able to open the frunk as a result), I've decided to install a short SAE extension cable to bring the 12v connections near the windshield where I can get at them if needed.
