hey guys,

i have 2004 audi a4 and when i tend to start my car my fan seems to be very very loud and blowing alot of air... but when i start to drive it seems to be fine and turns off.... any idea what it could be?

also my check engine light is on as well....

please let me know thanks

 

i had the same problem with my 04 a4. with further investigation i realized i have a big job on my timing cover gasket bcuz its leakin coolant
