Audi 2005 A3 8P 2.0 TDI COOLANT LEAK

[davidle123]

Hi all,

I have a 2005 Audi A3 TDI. Car leaked coolant around 200ml especially in traffic. Put K-seal which stopped the leak however after a few months noticed small leak on right hand side of engine without loss in reservoir tank. 

Anyone have any idea where leak is coming from and how to fix?

Any help would be greatly appreciated.

Are you sure you have no loss of cooant from the header tank?

Hi Mickey,

Thanks for the response. I have noticed that there is coolant loss from the header tank, about 100-200ml every few weeks.
