i was just wondering when is the best time to replace transmission fluid in my 2007 Audi A6 #.2 Litre alog with the timing chain not a timing belt but a timing chaing my car does not have a timing belt and according to audi or what i have read it is life time but i don't trust that lol. Also when is it optimum to flush your coolant thaknks a lot

 

yes the newer audi did not have timing belts. Chains will last the rest of the cars life. Just change the oil and maintain proper oil levels.

Change the tranny fluid around 60k before 80k. Use only the fluid from audi. Other fluids arent worth the hassle.

You may want to think about changing the water pump, thermostat and serpentine beltas well. If this is done the coolant will need to be flushed.
