Golf R Observations and Questions

[nickows]

My AC is very noisy. There is almost always a constant hissing noise when the AC is turned on. The hissing is noticable even when driving up to 60-70km/h. It disappears as soon as you turn the AC off (with the fan still running).

And the gradation between different temperature settings feels non-existent. 25 degrees feels just as cold as 18 degrees. I normally set the AC to a higher temperature (24-25 degrees) but it's still freezing.

Anyone else experiencing this?

Hissing is normal, no?

I remember back in the day when it was seen as amazing to have a 3 speed fan. Now we are complaining about how little difference there is in the temp we can set in one section of the car.

I don't remember much these days.

No idea what happened yesterday.

Maybe it's the cold air from the AC

If it's a loud hiss then maybe a vacuum line has come off an actuator or one of the flaps isn't closing properly - hence no discernable difference in AC temp.

Hi Nick, don't notice any hissing from mine and in the 40 ish degree days we had in Perth recently the temp difference between 25 or 18 was significantly noticably. Also when on moderate days you can notice the temp changes and on lowest fan setting no noises except the fan motor. I'd say you may have a problem, aside from that you enjoying the R? I still love mine after 2 and bit years and 40,000 kms
Cheers

It's an observation, not a complaint. I haven't experienced this AC hissing noise in previous cars, and interested to hear some constructive feedback from others if they are experiencing something similar. Isn't that the point of this thread?

Thanks for your helpful reply. I'll check it out and mention it when the car goes in for service.

Can't we all just get along?

Wait a minute, this is vwwatercooled.

Speaking of AC, I noticed today when trying to look around a truck (moved head closer to window) that the AC doesn't cool down the car, as I immediately felt warmer. Only when the air is hitting me do I feel cool. Which explains why when I turn it off the car feels hot so quickly. Not sure if that's a problem or not.

Does boost get pulled down in hot weather ?

I know power will be down due to hot air but what about boost ?

Edit - never mind, it does, 49C has an impact

All good.
