no warning lights i wondered if it was the turbo car has done 13000miles but there is no smoke from exhaust ta

Yes what you are describing is in fact consistent with a failing turbo. The turbo impeller fins have become weak which is where the noise comes from they will eventually break off. The turbo can not be repaired and will need to be replaced.
