I have a 2014 Audi A4 3.0 TDI V6 Black Edition Quattro

  • The buzzing noise only happens after you have been driving for 2 minutes.
  • It only happens when the engine is on.
  • It only happens when its above 19 degrees when temperature is on low the sound fades off
  • I think it stops when the stop start system kicks in and turns engine off but starts again after engine comes on. (haven't been in enough traffic to be 100% certain on this)
  • The sound stops when the heater is turned off.
  • The sound comes from the dashboard area in front of the steering wheel
  • The sound reminds me of what happens when a speaker is picking up electrical static.

Car has been into the dealers they changed the AirCon pump under warranty thinking that would solve it, now they are saying they checked on a like for like model that did the same thing after 19 degrees. They says it must be a characteristic of this model. Does any one else have this issue its really annoying & Im sure this never used to happen with my vehicle nor the other 6 I test drove.

Any questions let me know
