Another great video, Sadel. You saved your customer a decent amount of money by checking the pins on that valve. Hopefully the tech that installed the connector onto that valve ends up watching this video and learns from it!

Really good video Sadel! very important to know how a system works and always performed a visual inspection! I thought you would used the math channel to get the resistance of the solenoid! We've learned a lot from you brother! Very well explained!

Excellent video!!!

Great work 👍

Another quality content👏👏

Great video, and very well explained, new subscriber here. thank you for sharing your knowledge.

It looks like since compressors with solenoid vale always working summer and winter and only the flow of gas is controlled not the rotation and rotation never stops they break down and get damaged more than the compressors with clutch why they make this type of compressors.

I was wondering why the scan tool showed 0.66A even though the N280 valve was disconnected because of the bent pins. Then I saw at the end of the video that top N280 value is for the ‘called’ current and the second line is the actual current. So when you started the actual current was zero. When you fixed the pins, the Actual current was 0.66A. So, this could have been diagnosed and fixed without evacuating the gas.

Great video and my vw jt. I did change my valve it's now working

Great vid. Gonna be replacing the valve on my VW Passat compressor. What’s the easiest way to evacuate the lines without that machine?

Thank a lot for this. You explained it really well and rather than just replace the valve you gave a proper root cause. I’m assuming you need to remove the refrigerant gas before you removed the solenoid. I’ve got a 2015 tt and believe this uses the same valve with no cooling. Thanks man.

Great video I'm jealous of your tech lol

This was truly excellent. It's nice to watch a qualified mechanic. I am debugging the AC on a 2015 Golf. I don't have a scope but with the valve disconnected, the leads from the AC module read 4.5v. Your scope read 12v because the scope can measure PWM. Does 4.5 on a meter sound about right? I am waiting for an empty connector to arrive and then I will ohm test the valve. Comments welcome.

Nice work

Good stuff

Great video tanks for the information from YUMA ARIZONA

Thanks!

Great Video and good honest fault finding - Had a question regarding the voltage to the regulating valve on the compressor that you fixed - is it a steady 12V when it is turned on or is it a more complex pulse signal? ie the valve is not just open and closed it oscillates with a pulse signal?

Question is how did pins get bent? And why someone was disconnecting or someone on purpose bent pins in order to to tell customer that he needs new compressors?

My vane ac compressor (middle bolt)not rotating when turn on ac, it may locked up and couldn't turn by hand tools when take off from the car

Hello, I have almost the same issue with my audi a4 b9. The A/C starts to work only after error reset and than works for a very short time. The VCDS shows "65655 - Regulation Valve for A/C Compressor B11AE 15 (009) - open or short to plus confirmed" I checked the voltage is suppling to the valve. The valve coil continuity is closed and the resistance is around 12 ohms. I am going to replace the valve. Please, advice is there an non-return valve before regulation valve or I have to evacuate the refrigerant before take out. Thanks in advance!

Should the gas be degassed from the circuit while the valve is being replaced, or can it be replaced without degassing? Thank you

Can the solenoid be ok (good voltage, amps, resistance and good click when 12v applied) but the mechanical stuff be faulty?

I just have the valve replaced, but the AC still doesn't work. Now I'm wondering if they bent the pins?😕 2013 VW Passat. Do I have to replace the compressor it self?

does removing this part releases all the freon out of the system? i have a 2013 vw beetle
