I have an 2001 Audi a4 1.8 liter turbo ,it leaks antifreeze.

What is your question?

I had water pump and timing belt changed on it and it still leaks ,I also changed the back flow reservoir on it .It seems to leak once car is turned off, seems to be on drivers side but can't see the leak.i have to put antifreeze in it every couple of days or it will run low and.cause car to overheat,any idea what this problem could be and is it an expensive fix. Thank you

What makes this problem better or worse?

Don't get heat when car is parked only when driving

How long has your 2001 Audi A4 had this problem?
