Macan a/c not working? have fault codes

Recommended Posts

Hello, new to the forum first time posting here! Have a 2018 Macan base and the a/c doesn’t work. I bought a foxwell NT520 pro scanner and it scanned all the codes of the car and came back with 4 fault codes for the a/c. 




all three of those say Passenger compartment sensor-short circuit to ground or open circuit. 


says please refer to vehicle service manual. 

If somebody could help me understand these codes because i have no clue what the passenger compartment sensor is or where it goes. Thank you!

As  I recall the sensor is in the ducting panel under the dash.



Hey, thank you so much! I will have to open up the ducting and check out the sensor and see what happened. Hopefully it is just a faulty sensor!

Hey you are the best! so turns out that sensor was the problem. It was just unplugged from last time that we opened up that panel 😅 completely my fault. Now after driving it for a week i have another code for the water pump relay. Do you know where the water pump relay is on the macan? Thanks

Did you try clearing the code and seeing if it comes back?

Yes i clear the code and it keeps coming back, its the only code active and i have no idea why. I never did anything with the water pump. Code says “water pump relay, short circuit to b+/open circuit”. So im guessing something with the relay ?

What is the fault code please?

So the water pump relay code went away after driving a day but now the only code i have left is d10002 and it says please refer to vehicle service manual. I think i either need a better scanner or ill be taking it to a shop 😕 the problem is i work monday-friday and cant get the car to a shop because they all closed on saturdays. Thanks for the help

The inner temperature sensor is located on the right in the plenum panel (at the air inlet housing for air conditioning).




1. Unscrew fastening screws and remove air inlet housing cover 2.



2. Turn inner temperature sensor clockwise arrow and remove it to the rear.



3. Disconnect connector 1 from the inner temperature sensor 2.



Installation is performed in reverse order.
