Re: 2021 Volkswagen Tiguan Facelift Review I am a newbie to the forum. My membership was approved couple of days ago. Delighted to be here.
I got the outgoing VW Tiguan delivered on 25th Jan 2025. Coming from a Innova Crysta Diesel Automatic, the only issue that I am grappling with in the Tiguan is the performance of the Aircon. Heat trapped in the cabin when parked under the sun during the day is unbearably high. With return to office, getting a basement parking is a touch or miss on most days and the car must be parked in open space if the parking gets full. The first few weeks, I simply couldn’t fathom with the cooling efficiency of the aircon. The car would take a couple of hours to let go of the trapped heat.
On the date of delivery, the dealership pushed the accessories package down my throat. It came with the following for some Rs. 28k. More later on my purchase experience and why/how I ended up buying the VW Tiguan.
1. USB CHARGER and C TYPE CABLE | Part No. 000051446CT
2. All weather floor mats (Rear) | Part No. 5NA061512 82V
3. All weather floor mats (Front) | Part No. 5NC061502 82V
4. Mud Flap (Rear) | Part No. 5NA075101
5. Mud Flap (Front) | Part No. 5NA075111
6. Tiguan PA Car Cover | Part No. 5NC061205PACOV
7. Magnetic Sunblinds | Part No. 5NL064365PASUN
8. Door draught deflector front, Smoke Grey | Part Number: 5NA-072-193-HU3
The magnetic sunblinds come in 4 pieces (2 for the rear windows and the 2 for the rear quarter panel). I use them to reject some heat.
I also used the Door draught deflector (aka rainguard, wind deflector, door visor) and close the glass leaving 5 mm or so open for the hot air to escape.
The amount of heat trapped continued to be bothering.
Searching through the forum, I bumped into the VCDS coding thread and got in touch with Dr. CodemyVAG in early March. The tweak on the aircon settings improved the cooling a bit, let's say 10-15%. I used to set at 22ºC to get a comfortable cabin temperature and now it's between 24-25º. Don’t catch me here for the math. I kept comparing this to the cooling efficiency of the Innova Crysta, only with the front aircon turned on and simply couldn’t accept the aircon performance from a vehicle in this segment.
Next, I explored heat-rejecting film on the panoramic sunroof and got the ASWF Excel IRP 45 (45% light transmission and 53% heat rejection) installed. I can say this has largely reduced the heating. My installer suggested to go for ASWF Excel IRP 70 (76% light transmission & 44% heat rejection) for the windshield. Out from a covered parking lot and 15-20 mins driving with the sun in front of me, the dashboard was absorbing so much heat that one could not touch the surface. Again the Innova Crysta comparison. Toyota had got the heat rejecting windshields right and the dashboard has never gotten heated. I am sceptical about the enforcement of regulations on heat rejecting films on windshields. We never know when the cops pick up this topic and start enforcing and hence haven’t done the windshield films yet.
ChatGPT suggested the below AC Boost Trick:
• When you get in, open all doors/windows for 30 seconds to vent trapped hot air.
• Then close everything and blast AC at “LO” with recirculation OFF for the first few minutes.
• Once the cabin is cooling, switch to recirculation ON.
Tiguan has a feature wherein, I press and hold the unlock button on the key fob, all the window glasses roll down and the sunroof lifts up. I do this when walking towards the car and is in my line of sight. This lets some heat out. I then do the AC Boost Trick above.
In spite of all the above, my trousers get damp out of sweat in 20-30 mins. Is the seat cover real leather or something synthetic that doesn’t breathe? I am thinking of using a cotton towel in such circumstances, but concerned about spoiling the aesthetics.
My friend in Chennai who owns a Tiguan too says that he has faced no such issues and that the aircon works just fine.
With that lengthy background:
Q1. What is the recommendation on heat rejecting films for the windshield
Q2. Any other Tiguan owner observing the same issue?
Q3. Anything wrong with the Aircon performance? I always use it with recirculation on. Anyway to check if its performing as designed? |
