ok thanks.. i replaced it with a new one already and my temp gauge is now working, i have a quick question, after replacing the ect, i run the car to check if the temp is working fine but i noticed that my temp now goes on the half line? is it normal on audis? or do i need to put some more coolant on it? coz on other cars the normal is below the half line right?

 

Mine usually stays on like 200 (little below half) Im not sure more coolant is going to bring it down significantly I could be wrong though how much do you have in now?

 

half is good anymore isnt so good

 

Halfway is normal. As for coolant, two 1.5L bottles of G12 and water for the rest, filled to the full mark on the reservoir. Long as that's what you've got, you're set up perfectly.

 

i think i didnt put enough coolant in there.. im already in a full mark on the reservoir.

 

i have a quick question guys. my friend has a 99 14 1.8t. and he was telling me that he put a prestone anti freeze coolant(yellow jug) in his car. is it safe to do that? even if the thing said on the jug is (can mix with any color of anti freeze)? what will happen if its not good? thanks guys, your help would be highly appreciated...

 

he needs to drain that coolant and replace it with G12

 

My car will usually sit at halfway when i'm driving. That or just slightly lower
