Loud low and high pitch rattling noise was coming from it. We completely dissembled rotor site and gearbox side. First coolant penetrated external rotor shaft ball bearing on rubber shaft seal, it was overheated and damaged. Coolant then enter ball bearing and flushed oil lubricant. Second spot of failure was internal ball bearing on first gear from rotor, probably because of damaged rotor bearing. And third spot was High voltage cable water ingress. Lets say 9 years and 320000km without any servicing made some marks on it, but not unsolvable. This drive unit cant hold more than 250000-300000 without gearbox lubricant change, gearbox cleaning and ball bearing change. Big output power of 280kw should be maintained. First signs for servicing are covered by 3 universal rules: 1-noise 2-vibration 3-oil/coolant/body overheating. If you hear any of that, it is better to prevent bigger damage.
