I received a download and halfway through it it appears to crash as car went into like deep sleep. Didn't charge eventually was able to get it after 3 button reset car woke up. I started to get all these Alrms BMS_f027 , GTW_w018, DL_u014 Low coolant even though not low . Tesla called car in after it stopped 1500klms awY from service centre they say we think it's the Drive unit . Not convinced any other people had this problem.
