A/C regassed still not blowing cold

[WhO]

Definitely look at the fans first. The low side pressure is high but that may just be as a reaction to the higher than normal high side pressure. If you don't have properly working fans (they should come on low as soon as the a/c is turned on) what will happen is the high side pressure will get too high as the heat is not being removed from the condenser. Sounds like your fans aren't turning on low at all causing the high side pressure to rise high enough to get to the point that kicks in the high speed fan circuit. The fans kick on high but the heat already in the system is too high and the system pressure probably rises too quickly for the fans to get on-top of the job causing it all to shut off when it gets to the high pressure cut-off.

No point in trying to diagnose / fix further until you fix the basic essential components of the system. Fix the fans so they work on both low and high speed then if the a/c continues to play up diagnose further.

Also on a side note my fiancée's sisters Bora had the issue that the a/c kept cutting out / making some nasty harmonic noises on hot days / under heavy heat load. Threw gauges on it and the system pressure was through the roof. Fans were working ok so Evac and recharge and all worked perfectly. Appears that the system was rather overcharged. Probably as a result of some shop thinking the more gas the better the system will work...

have u changed fan control module?

have u changed fan control module?

Havnt changed that, as I don't want to do the old "replace stuff that doesn't need replacing". Will test the high and low speeds tomorrow.

im still having issues with my air con.
which fan is the aircon fan? passenger or drivers side?

i turned my aircon on and had a look at the fans and only the drivers side spun.. and the noise was pulsing on and off.. the passenger side fan did not turn.

Both fans work in tandem so if only one is spinning you have a problem! I had an issue with my fans when only one was turning on low speed, ended up being Brushes that were stuck away from the commutator. Ended up having to pull the fan apart to fix it, was a relatively easy repair but a bit time consuming.
Check your radiator/condenser fan operation NOW - Page 54 - TDIClub Forums Pictures half way down this page give you an idea of how the fans are put together and what can go wrong.

[BL33SU]

can you explain what you mean by work in tandem?

i had a read of the TDi forum but pictures dont appear for me..
is there a easy way to put direct power into the fan to see if it will spin?

also read there is a cooling fan relay under the dash 40amp 4pin type... they even sell that as a part on ecstuning saying replace that if your A/C is not working first.

[WhO]

Both fans should come on together on both low and high speeds. Essentially they should each be doing the same thing at the same time.

Not sure if there is an easy way to trigger the fans, There is a relay you can trigger i believe, pretty sure its how i tested mine but i cant remember how i did it:/

I've embedded the images of the stuck brushes from the TDi forum below, hopefully they work:

i decided to take a better look at my fan... the passenger side fan does not even spin freely!

the drivers side will freely spin when i rotate it.. but passenger side is very hard and its like stuck!

so would that mean my fan is gone? or should i try use some wd40 lol

[Stan]

Sounds like the fan is stuffed

Purchased some cheap eBay resistors, will find some scrap aliminium during the week and hopefully rig up something next weekend!
Even if it does nothing to my a/c at least I have piece of mind that my fans are working correctly!

i just tested my fans out finally and there is no low speed... so i will also need to go buy these resistors too!
not sure if i wanna cheap out on them from ebay tho.. dont want them to fault quikly lol

[Stan]

my ebay ones have been going for a while now - running fine, they do get hot though

[undisclos3d]

Made my resistors up today put the car on the hoist and looked for the place to mount it
And realised that because I have a cai, it goes through the place where you mount the plate! So does anyone reckon if I cut the plate down quite small to make it fit somewhere nicely. Would it matter that the heat sync is like half the size? Would they fail sooner?

[Stan]

dont know about how the heatsinking properties will be affected (however I do know it gets hot, so i wouldn't go a lot smaller....), but simply find a new place to mount it. I'd you the same amount of aluminium, but just make it square or other shape that fits in somewhere else.
