Hi,

Lately I noticed my A4 3.0 Quattro started to make a noise when engine starts in the morning. at first it starts at 1200rpm then after minute goes to 800rpm and then when I push the gas makes weird noise around 1000-1500rpm, when is higher then 1500rpm it's stop making a noise , when rpm drops noise comes back and stops below 1000rpm, It does on Neutral or Drive for around 5-10 minutes. Along with this noise I can also feel some vibrations when holding steering wheel. Any ideas before I will send it to a mechanic??? Thanks in advance!
