Thread: Slow a/c on D4

Thanks for the "supportive" comments fellas...


Yes I'm thinking the "stop leak"should be called "stop valve". Not too impressed. This was from my local Automasters, they advertise an AC regas "from $160".

And another ‘supportive’ comment,many seem to advertise “regas”.

As per mandatory requirements,there is no such thing in a modern vehicle.
If the refrigerant disappears,the system leak must be located and repaired.The system cannot be filled with refrigerant if it is leaking.

The hoses and seals on modern vehicles don’t leak,like they did 25 plus years ago.

I think the price is fine Eric, it does take a few hours to do plus consumables. And they have the gear and accreditation to do the job.

Thanks Josh, i have no issue with the cost, understand there is time involved, labour, overheads and consumables etc. What I have an issue with is the system was ok before the regas, now it "seems" worse (albeit my last reference point was a 42deg day), and some on here are suggesting that the "stop leak" is the culprit, I suspect this may be true and causing the PCV in the compressor to stick...

Will go back to the service provider, job was done last April, I read the invoice, max 6 months limited wty. Will still give it a go...

How many kilometres on that compressor?

True, that too 206,000km

About 5 years ago I did the valve in my wifes Golf. Over the last year it's started to get "sticky" again to the point where it was taking several kilometers and possibly a few high-rpm blasts to get it unstuck. Once unstuck it worked ok.

On the weekend I thought I'd follow a hunch, so I removed the r134a and replaced it with a Hydrocarbon blend (close enough to Hychill minus-30). Thus far the results have been positive.
