If there had been a question of what it could be, it can only be described in insufficient detail.
I've had such a strange buzzing for a week, similar to the buzzing of a defective petrol pump, but comes only with operating warm engine

From the feeling it comes from the left area of the engine compartment.
Climate compressor warehouse is probably defective with me, came also after the climate service at Audi
When I turn off the climate the noise is still there ergo it shouldn't be from the camp.It also only occurs when one passes from the sliding operation into the thrust operation and always, not only sporadic.
Was könnte es noch sein?
Have a nice Christmas.
Greetings Micah
