What are the reasons for the Audi A6 generator not generating electricity?

[SiennaFitz]

Audi A6 generator not generating electricity reasons: 1. The intake air temperature or water temperature is too high, and the cooler is blocked: the intake air or water temperature should be reduced, and the blockage in the cooler should be removed. Before the fault is eliminated, the generator load should be limited to reduce the generator temperature. 2. Too much or too little lubricant is added to the bearing: lubricant should be added according to the regulations, usually 1/2-1/3 of the bearing chamber (the upper limit for low speed, the lower limit for high speed), and it is advisable not to exceed 70% of the bearing chamber. 3. The bearing is worn, causing local overheating of the bearing: check whether the bearing has noise. If the stator and rotor are found to rub, stop the machine immediately for maintenance or replace the bearing.
