In the process. I had cell number 11 dead. The car has been in the shop since last Thursday. Expecting it back tomorrow. Then I can report. I have concerns this is a design flaw or bad quality control on batteries. Never seen this volume of complaints for a relatively small car volume. I suspect a lot of people don’t even know something is wrong. Just upset on the poor range.
Hi CarZin, I am having exactly the same problem with my e-tron 55. Started with a full range of 225 miles when new and now 2 months later, struggling to get over 150 miles on full charge. Also having the same issue with the 80% power mode you mentioned. Some days i have option for full power (boost mode) and others just 80%.
Did you get yours sorted in the end?
