Engine Mechanical problem
2001 Audi A4 4 cyl All Wheel Drive Manual 130000 miles

Hi.
Thank you for your respond, This morning the oil warning light come on and the engine make noise but it happen only when I change from neutral to first and second gear at low RPM (under 2000RPM), about a second, at high RPM the noise disappear and seem like engine lost little power. I take to the shop they say will change the air valse or (sensor ) will it take care the problem? I am not sure, can you help me please. Thank you again.

If the oil light is on adn the engine is making noise, it may be a little more than just a sensor. Did you check the oil level to see if it was full? If it was full, have the shop verify oil pressure with a manual gauge. Always use the manufacturers suggested weight (viscosity) oil and high quality filters. These two things can create oil pressure issues as well

Hi.
The check engine light come on and oil pressure light too, I check and get the faulty code: secondary air injection system incorrect flow, car still runs with a little noise at low RPM ( under 2000 ) When engine runs from gear to neutral I can hear the noise like the air exhaust out. Please tell me what should I do, replace secondary air solenoid will fix both problems? Oil level is good. Thank you for your help.

If it was full, have the shop verify oil pressure with a manual gauge. Fixing the check engine light wont do any good if the engine has an internal failure due to lack of oil pressure. You will need to eventually fix any exhaust leaks before diagnosing a secondary air injection issue.
