Svenska Posted February 27, 2014 Report Share Posted February 27, 2014 Can someone tell me if there is an endemic problem with the '05 XC90s and an engine whining sound? This is the B5254T2 engine. When accelerating there is a noticeable whine that increases with RPMs only when in drive, not idling in Park. It almost sounds like a turbocharger wind-up? Does anyone know what it might be?

Ihatespeedbumps Posted February 27, 2014 Report Share Posted February 27, 2014 You are likely hearing the turbo. Yes you will hear varying degrees of whine, usually worse when cold and if the windows are down. Check the steering shaft in the cabin and see if there is a lose bearing around the shaft. If not installed properly it will greatly exaggerate engine noise. Link to comment Share on other sites More sharing options...
jschaefer7406 Posted February 27, 2014 Report Share Posted February 27, 2014 As Josh said, the small turbo's on these do make a good deal of noise. I know our '06 does Joe Link to comment Share on other sites More sharing options...
Svenska Posted February 27, 2014 Author Report Share Posted February 27, 2014 Wow, that loud huh? That just doesn't sound normal though compared to other cars... It's been cold all week and it just started this morning. Link to comment Share on other sites More sharing options...
