TESTING n280 AC variable displacement compressor regulator with a “test light” (volkswagen audi)

[@Tyranthraxus]

Great video , what's even better is I have a B7 A4 too, so this information is almost identical for my diagnostic process. However, I am sure it is useful for any solenoid / variable compressor diagnosic on VW/Audi. Thanks for putting together.

Congratulations my friend, simple, clear and excellent explanation, just for that I subscribe. Note : I am using the english subtitles, at the moment i'm learning english. Thanks for sharing

[@powrpacks]

so what was the fix??

Thanks sir very good sir 👍👍🙏🏻🙏🏻

[@kpraz]

does the n280 valve have correct polarity? or can it be sent voltage eitherway?

Hello i have the same problem with my audi a4 b7. 5 volts at the compressor plug. How did you resolve the problem with yours?

[@fightercivilpilot3078]

Very nice

Sooo if it clicks it's still good?

Couldn't you just run a wire from the cars fuse box and have it on a switch?

The evaporator would freeze. The computer sends a pulse width modulated duty cycle to the solenoid to control the temperature based off of sensor inputs. 100 percent on would freeze all water vapor or humidity to the evaporator eventually air can not pass through it.

@@kristenewilson2475 PLEASE HOW I CAN GET PWM WITH small tools and DID the 12V damage the selenoid
