Most of the time, when your Passat’s air isn’t blowing cold enough, it is going to be a lack of refrigerant causing the problem. We recommend having a professional recharge your A/C if it does end up being a coolant issue. If you put too much coolant into the system, you can really do some damage.

Where does the coolant come from on a VW?
Follow the intake manifold down and you’ll see that big metal box with coolant hoses coming out of it. That’s the intercooler and it’s cooled by coolant. At least take it off and pressure test it. Then put it underwater and bubble test it with compressed air.
Can a TDI cooler leak coolant from the intake?
Only gas models. TDI= oil cooled only. The EGR cooler could leak coolant and go back into the intake through the EGR. Remove the intercooler and pressure test it underwater. Only other place coolant sees intake is the EGR cooler.
