e-tron just back from its extended first annual service. Essentially this is just the mandatory 12 month / 9,000 mile oil change (list price approx £220), but I wanted them to check out a few issues like communication problems with the e-tron app, strange noises going from ICE to EV and no EV available on some cold mornings. In the process of diagnosing the e-tron app problem, the discovered that LTE antenna #2 (located behind the rear bumper) was faulty so that was replaced under warranty (list price of £504). They were unable to replicate the ICE to EV noise problem and stated that EV mode can be unavailable sometimes in cold weather because of potential condensation problems. Overall, the service was professionally carried out and well documented by the dealership, giving my e-tron a clean bill of health for its second year. Furthermore, thanks to my missing illuminating door sills it was all free of charge.
