hi everyone. I have a 2012 superb estate. It's the 2.0 tdi elegance dsg and ever since owning it, I've noticed that the heaters blow cool air until the climatronic is set to high. It's been in the garage for some warranty work and they've said they can't find any faults. Is this normal? I had it on 25 degrees when I took it there and it was still cool. Engine temp was at 90degrees and had been driving for 170 miles so well up to temperature. Any advice would be appreciated. TIA. 

Any idea what the ambient temperature in the car is when the fans are blowing cool? I'm not an expert by any means, but if the ambient temperature in the car is / was 27c (for example), then setting the climatronic unit to 25c will result in cool air being blown into the car until the cabin temperature comes to 25c. As I understand it, setting the temperature on the climatronic unit isn't telling the system to blow air at 25c full-stop. It's telling the system to get the cabin temperature to 25c and keep it there. Depending on the current cabin temperature, that might involve blowing air that is much colder (or warmer) into the cabin for periods of time at a stronger or weaker circulation (fan speed) rate. I think changing from Auto I to Auto II increases the agressiveness of the system (as in, it will attempt to stablise the temperature more quickly).

 

If it's still blowing cold air even when the ambient cabin temperature is 9c (for example), then you probably do have a faulty sensor somewhere. If you can, try to measure the ambient temperature in the cabin and the temperature coming from the fans to see what the readings are.

 

Personally, I do find the climatronic unit a little on the chilly side in summer, but I just angle the vents away from my face (rather than closing the vents) and I feel perfectly comfortable. But if I have the fans pointing at my head, I feel quite cold (for obvious reasons).

Thanks Declan. Car went back for some bits under warranty as Ive only had it a month. Asked them to look at it as I wasn't sure. They've fixed the twisted seatbelt and sat nav but also went in as the front heated seats Wernt working properly. Drivers side not at all and passenger side just the back worked. Now I have a heated drivers seat base and the back on the passenger side still 😥 annoying as I love the car......
