What kind ofnoise does a broken turbo make? I had a decat pipe fitted and had the eml come on when i put my foot down. i reset it and it went and has not come back on. the turbo over the last month was pretty inconsistant holding boost. But since then it has been everytime its on full boost, it also makes a different noise on full boost, more of a high pitch noise. It sounds the same as it used to on lower boost.
No smoking on boost at all, and not losing a massive amount of oil.
so i dunno if this noise is a problem?
