    I see the part in AutoZone's website. I have a 2006 Jetta TDI, and the OEM part number for the compressor is 1K0820803L (the PXE 16). I see in the Polare Bear website and others that this part fits the PXE16 OEM part 1K0820803S (with an "S" at the end instead of a "L"). Do you guys know if I order either the AutoZone part shown above or the part from Polar Bear's website (http://www.polarbearinc.com/PBPC/Homepage/products_Comp_Valves.html#SD6V12) which is EX 019 would work?

    Do you have access to the set of A/C gauges? You might check the head and suction pressure before you say the compressor or compressor valve is bad. On some vehicles if the system pressure is very low (no enough R-134a in the system) it will not engage the compressor or even the condenser fans. Make sure the fans are working when your engine gets hot just to prove that they are in the operational state.

    It looks like I'll be doing this fix in the coming weeks. I just need to confirm what valve I have, and then I need to find a shop which will evac and fill the system for me.

    I'll post back with updates.

    The oil loss was minimal. The system is still blowing cold to this day.

    Well, I celebrated too quickly. A/C blows cold BUT it's now always on. I think I put the wrong valve in my compressor. The new valve was shorter but the O-rings appeared to be in the same position. Would the wrong valve cause my situation? I told my wife I upgraded her to climate control! If I screwed up the electrical connector somehow would that cause the compressor to be always ON or always OFF?

    This is the valve I bought for my 2012 Sportwagen TDI:

    Does three different sets of floor mats count?
    If the valve is shorter, when in the fully powered up state (closed) it will not reach the back of the body to close off refrigerant.

    That's what I figured. Time to do it again with the proper valve. Thanks for the response.

    Wanted to report another success with replacing this part, in my case on a 2011 TDI Sportwagen, 119k miles. Snap-ring part, my mechanic was happy to do it with the part ordered from polarbear. Never had even close to functional A/C in the year I have had this car - it's a huge improvement! My mechanic was glad to know about this fix, though he said he'd not seen this problem before. I bet he'll see it in the future.

    Happy to report that the second valve was correct and the A/C works perfectly. A necessary luxury on the MS Gulf Coast!

    My 2010 Jetta TDI Sportwagen has had this problem for a while.I was planning on fixing it myself,but while visiting Monterrey MX I decided to check a local European air specialist.It was a small shop,but he knew exactly what I was talking about.I noticed four or five old valves laying on his work bench.I seems mechanics here try to fix things before replacing a complete assembly.They replaced the valve charged the system for 225 dollars.The air is much colder now and thanks to the information on this website I saved a lot of money .Thanks

    How hard is it to remove the valve (circlip version)? Any tips? It looks really tight in there with the radiator fan.

    Paid to have mine done,because it does look like a tight fit.When changing my oil I had to remove my skid plate, and realized from the bottom it is easily accessed.If I understand correctly there are two different valves for that compressor https://www.coolairparts.com/index.php?route=product/product&product_id=2366 and http://www.coolairparts.com/index.php?route=product/product&product_id=1899 some say if the o-rings are in the right place either will work,but I have read if you have the longer of the two and you use the short one you will have cold air but the thermostat will not work properly.I need to check on this as my car cools no matter if I have it set at 64 or 82 degrees.

    Hi, I have a 2005.5 A5 Jetta TDI and live in Fl. at about 100,000 miles the A/C started to take 5-8 minutes before any cool air was felt. Like it was not working at all. Just warm air. Then it get cool but never "icy" cold any more. Then it goes from cool to not so cool and back to cool as driving continues. Its like the compressor is just not putting out the correct pressure for the cooling.
    I brought it to a shop in Vero Beach and they pulled the system down and recharged it and said the compressor needs replacing because the pressure are not right, $400 + $60 for a dryer and another $500 for the labor.

    My question s:
    1. Does a new valve come with the new compressor or is that a separate part I may need anyway?
    2. Should I just get a new valve and try that first?

    I bought the car new and now have 120,000 miles on it.

    The new compressor comes with the ccv.The ccv varies the output according to demand,so I think it is possibly the problem.It looks like there are two different style compressors for that year.One has a ccv and the other is the old style without.I guess you need the compressor number to know which you have.

    I think it is a Sanden compressor but will open the hood and get the number.
    Thanks

    Can't see anything numbers from looking at it. Since it turns all the time I guess it could be worn out.
    Funny it does not cool for the first 8-10 minutes.
    Wonder what gets it going? The valve sticking? and then, it does not cool like it use to due to lower pressures. Valve again or maybe compressor?
    Can I tell which vale by how it is held in? Bolt or c clip?

    Does not cool for first eight minutes sounds like the ccv it varies the refrigerant according to demand.The numbers are usually on the bottom side of compressor.Some have been able to get their cell phone in a position to get a picture of the numbers. Scroll type compressors do turn all the time,the ccv controls the refrigerant.There are two different valves for the type held in by c clip I do not know about the old style.Call https://www.coolairparts.com/index.php?route=product/product&product_id=2366 they should be able to help.
