Last few months I detect that I do not get maximum power at full throttle. In white performance mode the kW meter originally reached 200kW and is now reaching not more than 150 kW. The roadster is 6 years old. CAC 132, mileage at 240.000 km First I expected this reduction caused by dirt, since my last service was 1 year ago. However after service last week, kW power did not improve. Do other Roadster owners experience also a power loss probably caused by aging of the battery pack? Or is there another cause for this?
