My ibiza 2008 1.9tdi pd has started making a different turbo sound when the engine is at normal running temperature. When it is cold the turbo still makes the whistling sound, when warmed up the turbo makes more of a whining sound. It has full service history and has done 102000 miles. Had it remapped 2 years ago to 130hp by evolution chips. The whining sound is not loud and is only audible with the window open. The engine is not using any oil. I use turbo cleaner in the diesel periodically. The performance is good as usual. Anybody else experienced this with variable vane turbos?

Could be a boost leak or could be early signs of turbo failure.

Leaks are very common, you probably have at least one if not more, usually the bottom intercooler hose which you can't see until you pull the arch liner out..
