Hey guys hoping you can point me in the right direction... I recently got a 2005.5 a4 b7 2.0t.. And I have a few questions about the Quattro... When turning hard I can feel whAt I can best describe what a truck in 4wd or with a locked rear end feels like but the car performs and drives as it should. Is this becAuse it's a Quattro? I'm new to Euro cars a d would appreciate the help... Thanks in advance. Also is 0w-40 ok to run in this car as long as it Carrey the 502,504.00 spec? Castral edge...

 

Yes, all awd/4wd cars have that feeling when turning very sharply. Should not feel anything when you make a normal turn though.

Oil needs to be full synthetic. As long as it meets the requirements it should be fine.

 

Mine does that mostly at parking lot speeds as I'm turning very tightly into a parking spot. The Torsen center diff on these cars is designed to multiply torque to the axle with grip. If I understand correctly, the diff tends to resist drive shaft speed differences front to rear. If you overload it's capabilities, though you can spin the wheels on one axle or the other, at which point the car employs the brakes to get the spinning axle back under control. When on snow or ice, you can actually see or feel the inside rear wheel slip al little in a sharp turn.
