Hey everyone, my google skills have failed me, and I’m low on cash so I’m hoping to get some advice before I take it to a professional.
I have a 2008 VW GTI which I love and have maintained pretty well. I unexpectedly got a job far away from home and couldn’t move for two years (!) so right now it has about 70,000 miles on it (poor thing.) Luckily I now live about 5 miles away from work and it’s finally getting a rest.
Long story short is that the oil was overfilled during a routine oil change. Foolish me didn’t check the oil before driving away (i didn’t do the change!) I got about a mile or two before the oil pressure light and beep told me to shut off the car, which I did immediately, and pulled into a shop literally a block away. They bled out some oil and checked a few things out and everything looked fine. But as soon as I left, and to this day (about a month later) I get a strange whistling noise when the car is cold and at low RPM. It’s a constant noise and the pitch changes with the RPM (higher RPM, higher pitch) after warming up for a minute it goes away and doesn’t come back until the next time I start the car.
My guess is that oil got somewhere it shouldnt have, like the turbo? And now something is leaking, like air? The car drives fine, no stutters or significant loss of power. Is there a way I can diagnose the issue myself before taking it in? Or should I leave it be and let the professionals take a look? Thanks
