So it's fixed. It was the turbo. It had 50 thou play in the main bearing. My guy managed to find a used one with only 30,000 km on it. Cost me CAD 2,000 all in to have the work done but at least it's fixed.
FYI for a new one the way he put it was "it'll take 10 years and a million bucks"...
Ok so I tried to record the sound. Please see the attached files. Be patient, they are not that great and the whine is barely audible but you can hear it.
Thanks guys.
@neganox - it happens in gear, neutral and when the clutch is depressed in gear. There is no change in any of these circumstances. Therefore I don't think it's transmission related.
@Mauro_Penguin - It doesn't change when steering left or right so I don't think it's the pump...
Hi
I tried to search for this but couldn't find anything.
My 2008 speed 3 recently started whining at low revs and up to about 4-5000. At low revs it sounds like a race car transmission and then as the boost kicks in it's a high pitched whistle. It is related directly to the amount of gas...
