I've had my 8L 225 for around 2 months now and every so often (sometimes when water is around 70-90) my turbo makes an odd grinding like noise i've got no experience with turbos so me saying it sounds like a bearing will mean nothing, another friend suggested maybe injectors.
Sometimes this happens, sometimes it sounds beautiful, is that my turbo telling me it needs a service or telling me its time to buy a new turbo? (Car has done 100k).
Also hearing a squeaking/grinding when turning on full lock
Thanks for any help you can give, any more details just ask, please help me diagnose
