      My17 xc90 t6 Strange buzzing noise right rear when parked

      Hi...just walked into garage and noticed this strange buzzing sound coming from the right rear of our xc90. Car had been parked and locked for 6-7hours. Is this an Evap System process or what could cause this buzzing? It did not stop after unlocking/locking the car or opening closing the driver door. I took some video for better diagnostic.

      Thanks!

      That’s very weird. With two SPA XC90s I never had that. It doesn’t sound like the compressor for the air suspension. I’m not sure if you have it but it sounds different.

      It could be the evaporation system. Others have reported similar sounds coming from the right rear when parked. If you get a CEL, you might have a bad seal on the fuel door or something and the evaporation system is just trying to continuously reduce the pressure.

      No CEL and it stoped itself after about 5min. Figured this might be better known or documented.

      I think there's a section in the manual about sounds to expect. Can't remember for sure. I might be thinking of an appliance manual I read.

      2019 xc90.. Just walked into the garage and noticed the same thing. Buzzing sound from some where around the right rear passenger area. This threads a bit old, anyone know what this is?

      I have 2 ‘19 XC90’s and have noticed the same sound on both. Both of mine have air suspension too so I thought perhaps it was that. Interesting to read the same sound is happening to those without air susp. I’m not too worried about it as nothing seems wrong.

      As said earlier in the 2017, it is the fuel pressurization safety system (in my words). It is fine.
