If it was done under warranty then call the dealer, explain the problem and get it booked in for fixing. Simples.

Had it booked in yesterday, however it mysteriously dissappeard.

They had a quick look and couldnt see anything obvious so fingers crossed its gone for good.

that car sounds like a truck! awful diesel sound. Is that normal for a lexus?

The other sound is that of a water pump. Could be a belt. Also is similar to clutch throw out bearing.

It could have been the used water pump have rust that got polished off.
