Installed 2 new cooling fans and both continue to generate the same codes indicated previously. Both new fans sets appear good and come on for some strange reason when the engine is shut off for a second. Thinking it might be the CanBus Gateway Unit. Not concerned regarding the emission codes until the ac works.
Customer: replied 2 months ago.
It has a new 4 month old battery. Battery was dieing before being replaced although the old battery tested good. Seemed to resolve the issue with the new battery however.

Thanks for choosing Just Answer . I'm Wolfgang here to help!!

I am confident we can resolve your problem together. Please
understand that I don't know your skill level. In most cases when you have a problem
with the way the vehicle performs, specialized tooling is required to acquire computer
data/information or engine testing results. We didn’t build these complicated vehicles; we
just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the
vehicle either, so it may take a few replies to get to satisfactory results. Note there may be an issue where the complexity of the issue will require a Premium Service. This service will be an addition to the normal question cost. Usually it does not come down to this but keep in mind!! I am also going to direct you with the fastest, easiest and most common things to check first. Please be
patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in
return. I will also continue assisting you after you have rated me, if necessary. If there
is any reason I cannot get a positive rating, please let me know why “in advance”, so I
can go another direction for you. I am sorry you’re having this problem; I’ll help you
through it.
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.

If you need to hand this off please do...
Expert:  Wolfgang replied 2 months ago.

is the center nut / bolt is turning with the pulley or is it stationary?

second if it is turning tap with a hammer while running near the electric valve on the compressor does then cold air come out?

Customer: replied 2 months ago.
It is turning..
Expert:  Wolfgang replied 2 months ago.

ok tap the compressor and see if the a/c inside starts cooling?

Customer: replied 2 months ago.
Still nothing. A new AC Compressor was installed last year..
Expert:  Wolfgang replied 2 months ago.

well needs compressor again. need to flush the system out totally with new expansion valve and new dessicant assy. the fans will not come on until the pressure switch sees a change in pressure!!! it is activated because the aperage is .850 ma .

anything else?

Expert:  Wolfgang replied 2 months ago.

the valve is not sold separately!!

Customer: replied 2 months ago.
all the errors are generated from a bad compressor?
Customer: replied 2 months ago.
Error Codes
Expert:  Wolfgang replied 2 months ago.

no you wanted to worry about a/c and the fans . not the rest . if you want to go with the other issues a separate question needs to be opened for that part.

exact quote " I am going to address the emission issues after addressing the ac non working issue."

That is the site rules.

Customer: replied 2 months ago.
Which ones? How are they worded? Aside from the emissions mess..
Customer: replied 2 months ago.
At AdvanceAutoParts.com the compressor we installed do not have an expansion valve like the defective OEM one. Item number T168646.
Expert:  Wolfgang replied 2 months ago.

iI'm a VW dealer tech so i do recommend factory parts.!!!! If a compressor was replaced a flush is needed with a new dessicant and expansion valve because of debris in the system .

Expert:  Wolfgang replied 2 months ago.

let me ask you this also did you install genuine vw fans or aftermarket like the compressor?

Customer: replied 2 months ago.
On ebay the item number for the fans is: 331515734613
Expert:  Wolfgang replied 2 months ago.

not there anymore

Expert:  Wolfgang replied 2 months ago.

so in a nut shell you need a compressor, expansion valve and dessicant assy . Must have a flush done to the system to prevent damage on the new parts. then recharge.

anything else?

if not.....

I try to be online 365 days a year.

I only earn a paycheck when a customer rates me Ok, Good, Excellent.

This rating is VERY IMPORTANT! Your rating compensates me on my time and my expertise on your issue!

A lot of the repair information and fixes are hard to come by!!

I HAVE DONE MY PART IN HELPING YOU AND I DO EXPECT THE SAME WITH A 5 STAR RATING!!!

knowing you have other issues a new question needs to be opened .

So please rate me above!!!! Bonuses are also greatly appreciated!!!

If I have not addressed your original question to your liking yet, I hope you will reply and continue working with me, since your charged the full question value, regardless if you rate negative or not at all. If you rate me now, do not worry, you can still reply later to me.

Thanks
