Whining sound

[Dylan Coombes]

There's a strange whining noise when driving and can't hear the turbo spooling up anymore, also doesn't seem to pull as hard as it did. Thoughts?

 

[EvoMayhem]

I think we need more info than that.

Does the whine chane with road speed? Change with engine rpm?

Does it still boost ok? (Do you have a boost gauge to check?)

 

[Dylan Coombes]

Boost gauge is in the mail. It goes up when accelerating and whines down when it's de accelerating. Boost wise it doesn't feel like it's boosting as hard as it was

Again, does it change with road speed, or engine speed?

 

[Dylan Coombes]

I'd say rpm

 

[Hypo]

My guess is that something is failing.

↑ what he said. I think your turbo is eating itself.

 

[Dylan Coombes]

Stuck actuator possibly? I really don't wanna have to spend money on that damn turbo aye haha

 

[4piknup]

Is it only when the mrs is in the car?
Mine usually more grumbles at lower speeds though it increases with rpm to become a whine.
On occasions it is very loud and I need to turn the stereo up to drown it out.

 

[Benzo4gT]

↑ HAHAHAHAHA!

 

[Dylan Coombes]

if only

 

[warbo]

Bugger. U beat me to it. Let ur Mrs out of the boot! Or maybe not!

 

[Dylan Coombes]

had the bonnet open and revved the engine a bit from under the bonnet and didnt hear the whining so i guess its more road speed that it comes on?

 

[Benzo4gT]

Could be throwout bearing or something clutch related. Does it whine with your foot on the clutch and revving it?

Is it a constant whine that builds with speed? Does it change with cornering?

 

[Dylan Coombes]

na it doesnt change when cornering from what ive noticed. its not the loudest whine either. the car is auto

 

[Dylan Coombes]

Noticeably more the faster I drive

 

[evo-gsr]

Definitely not the Mrs?

 

[4piknup]

Wheel bearing.

 

[Dylan Coombes]

not definite but pretty sure haha. wouldnt it change when turning if it was a wheel bearing?

 

[4piknup]

Probably not.
Traditionally if it goes woowoowoowoo and louder as you get faster its a front bearing.
If it just goes wooooooooooo and gets louder then its a rear bearing.
I dunno why.
Jack up car and wobble each wheel to see if you have a loose bearing
