2012 Tepee 1.6 HDi 110, 220,000 km. There's a whirring noise I think is coming from the turbo blades after 1500 rpm when I step on the gas pedal and let it off while cruising. I took it to a turbo shop in the Ümraniye Industrial Estate. He said, "There's a small noise, probably coming from the hoses due to the vehicle's age," and sent it on its way. There's also a noise in the alternator bearing, but the sounds are different. I need a turbo maintenance and repair shop in Istanbul. Thank you.
