Hi Guys I was reading this morning@web to see if I can find someone with a similar problem maybe an answer for mine, so: a4 tdi 136 2012 59k on the clock is looking like develops now a rather strange noise under load..2nd,3rd,4th gear. I can hear it well in 2nd gear over 2200 rpm hence my fear for the turbo. I should say that the noise is more obvious as winter weather came in place. The car sound like an owl when I press the gas pedal but disappears after 2500 I guess . No smoke no lack of power just that noise. Had four people in the car and again under load a bit of noise occurred. Doesn t matter if the engine is cold or on 90deg. I ll take down to Audi as the car is still under warranty although the turbo might not be coverd.If you have an idea let me know. Adi
