Hi guys,
a few days ago I was towing a trailer and i noticed that my 1kdftv developed a high pitched whine, almost like a dentists drill that corresponds to the turbo noise, since then the noise has been there only under high rpm when I load the engine up, vehicle still performs effortlessly and idles perfectly. From my research and a bit of thinking i'm thinking that possibly the EGR is starting to fowl up and with more restriction is putting more load on the turbo. Have any of you guys had similar issues?
