Audi1.8t99

I have a 99 Audi 1.8t AEB and it has 341,000 miles. Just replaced the turbo and converter, it now seems to have a rattle during acceleration. Anything 2500rpm and up. Describing the rattle, it sounds like a little pebble inside a soup can but not quite as distict. Not sure if it's a pulley or something. Also, while driving this afternoon, on a hard acceleration uphill, the gauge cluster started beeping but no lights were on. So I'm a little u sure what's going on..

Changed the oil this afternoon, checked oil pressure, checked good. Beeping is still there. Bad power steering may be the culprit for the noise im hearing.

Sounds like exhaust rattle. Maybe tin heat shield either above the turbo, or the ones along the exhaust are rattling or too close to the exhaust. Also if you put a used turbo on, did you check that the waste gate flapper was nice and tight when you opened it, not loose or anything. The rivets on the wastegate flapper get loose and the thing will make all kinds of strange rattling.
