Not sure if this is just me being a numpty,

But since the trip to Aviemore last month, the turbo seems to whistle/wine more than normal...

It has 45K on the clock now.. seems to be a little sluggish from time to time..

Am i just over thinking? or worth getting checked out.. Its not as if the car is thrashed about btw

I think they all whine a little,mine does it slightly but no power loss.

Yea.. they do.. ever since I got it.. it just got a little louder lol
