^^ I own a Elantra with ACC and my Friend owns a Verna SX, i have observed that the system does not select fresh air mode when sudden cooling is required in auto mode.

Yes it does select recirculation mode at times when not required but never on hot summer afternoon.

Since all the i20's today are under warranty, I won't recommend this but this can be a possible solution best executed by an experienced AC Mechanic.

The text in bold in my previous reply is the portion which has not been quoted in your reply. I've already advised against this change. Buddy, no offense meant but please take note of the same in future .

AbhiJ, you should take up the case of your car with Hyundai aggressively as you've got a flawed AC possibly with a manufacturing defect. I again took my bro's i20 for a ride today with temperature being shown as 39 C (Error, unknown) and it was able to cool much better than my Santro contrary to some of the views here.

One of my friends has both, the Verna CRDI SX & the Sonata Embera (Petrol) in both the cars ACC always starts in the external air mode irrespective of the outside temp.

^^ I Personally own a Elantra and Punto EP, both have ACC. I have never seen any of the climate control system suck in fresh air when maximum cooling is asked for on hot summer afternoon in auto mode.


No offences meant but Instead of suggesting experiments as Permanently closing fresh air system and replacing the OE gas with deep freezer gas lets suggest some sensible options like contacting Hyundai. Tampering with AC system will not only void the warranty but might also damage the car.

.anshuman, the gas replacement may sound absurd to some but this is very much possible and has been executed. People who first talked of fitting Esteem's or Baleno's engine in a small Zen must have been laughed at and termed illogical but they've proven themselves.

Why don't ask a mechanic about how safe it is, they know the best.

I didn't get hook of my cousin but asked my uncle about the gas (he's an industry veteran), he said the gas which I'm talking of is R134 BUT advised against using it in the stock equipment of the car as a lot of mechanical changes are required. It's pure luck that my cousin's car isn't giving problems else it can be fatal.

This mod reminds me of how one BHPian got 175/60 R13 on Xing's stock rims and was pro-it even though people like Nikhil advised against it.

One of my colleagues, who owns a Subaru Legacy which has ACC, told me that the ACC occasionally lets in fresh air from out side when it senses that the air inside is stale beyond certain set limits.

When he gets the foul smell from outside, thats when he knows that the the air from outside is being taken in, he manually change the mode from fresh air to recirculation.

Though the exact working of ACC in different cars might not be the same, this may be part of the problem with I20's cooling, if at all the i20 has ACC. The smaller capacity of the compressor in i20 aint helping either.

Punto=~2500rpm
i20 CRDi=~2000rpm
The older i20 CRDI does 100 @ 2100 or 2150 rpm but definitely not at 2K rpm. So if the new i20 CRDI does 100 at 2K rpm, then I believe the other gears have closer gear ratios.

Default Problem Solved : More or less :)

Sorry for the delay in post the results after my "wash the air filter" experiment... but I did not want to post until I was 100% sure of its result.

Well.. it worked. After washing the cabin air filter, the air flow has increased significantly.

I have also STOPPED using the Auto mode completely - At least for peak summers.

With the combination of the two : The cooling is now MUCH better, and I used it the last couple of days in the afternoon, set at 24 C, Face Blower, Fan Level 4/8.

Overall I would call the cooling performance now : satisfactory.


Side Note: The Hyundai service station should have changed the cabin air filter when it was sent to them for a checkup...

One possible solution is to close the air blowers (sorry if the term used is wrong) on the non - driver's side if you are alone while driving.... This is possibly one of the solutions for fast cooling... I use the same in my i20

My friend took his i20 to HMP New Delhi and they replaced the gas to solve the problem but to no avail. Hyundai should replace the affected parts under warranty rather than taking customers for a ride.

Your car is also in the league of those affected by AC problems. Yesterday night I took the i20 for a ride and it was getting so cold that I had to set the temperature to 22c, while the temperature read 38c. The irony is that the previous owner sold this car because he wasn't satisfied with the cooling.
