Hi all,

I have an issue since a long time now with the air conditioning.

   - the air conditioning is starting only after 3-4 minutes when I start with a "cold" engine.

   - when I am driving, it works fine but when the engine is idle-ing the efficiency is getting worse, so driving in the city during summer is not nice.

 

I took my car 2 times to a repair shop, told them the issue but they just added more refrigerant - they said the level was not low but they added nevertheless. Lost money and the problem is still there afterwards.

 

What could be the issue?

Could it be that the compressor is getting "tired" and is not able to raise the pressure fast enough? Or maybe a valve is stuck on open?

 

Just did a check: repair shop says the refrigerant level was at 350ml and he added up to 550ml. Pressures with the engine idle-ing were 10bars vs 4 bars. 

Feedback was that the radiator is dirty with bugs and the fins are bent and do not cool well enough.

First step would be to take the front bumper out and clean the radiator. 

If this does not improve the situation then the radiator should be changed
