'08 C63 Airco not working,
Hey All,
so ive got my C63 AMG which the Airco is not cooling.
when i switch the airco on, it acts like it is working however no cold air is getting out from the blower vents, (ive had this issue since ive bought this car.)
this is what have i done so far,
i went to an garage who filled up the airco system, they added a collourize fluid so any leaks was easy to spot then, a total of 590grams went in which the mechanic told me then straight away they let the car run and hit full blow and airco on,
but straight from that point no cool air and also the airco hoses are not getting cold either,
the garage told me maybe the system was protected by an fault code that needed to be deleted before it let the airco system work again, so we checked it and there was a code and we deleted that (i forgot what the code said)
unfortunatly still no cold air, however after a couple of days i saw the airco condensor was leaking, ordered a new one and replaced the thing. i later went back to the garage and ask them to fill it up again and from this point it still was not giving me ice cold air.
this made me decide to buy a laptop with Xentry on it and had a multiplexer with it (always handy), now i can check the airco system myself,
it showed no fault codes (except when the battery drops below 11,4V) it gives me an outside air quality sensor error that should detect smog and anything wrong in the atmosphere, i can check all the temperature sensors which show plausible readings, i can see the RPM of the airco compressor which is also showing good figures, but still no cold air.
what am i missing here, after replacing the condensor i can not trace any leaks, the car is faultcode free, running compressor, enough refrigerant, all temperature sensors working.
im lost

Wesley

- What is the High / Low gauge pressure ?
- What is the system pressure using STAR?
- Did you test if the heater-blender door actuators are working? Sometimes they get stuck forcing hot air out.
- what is the reported temperature for the evaporator sensor?
- In the ML63 there is a solenoid attached to the compressor that goes bad presenting similar symptoms, maybe the W204 has one.
Good luck
