Hi guys newbie to the forum. Recently bought a mk8 civic 2.2 gt type s. Noticed when the car's left over night cold start up there's a bit of whine from the turbo when changing gear, lasts only a few miles then goes away. Is this something to be concerned about or is it typical of the 2.2 cdti engine. Car has no noticeable boost problems pulls decently. The car's a face lift 2009 model and has covered 75000 miles,been fully serviced. Thanks in advance for any advice if its problematic.
