My wife complains the heated seats in our 2011 Panamera Turbo aren't warm enough. For me and living in PA even in the winter, it is the lowest heat setting that I select; one bar out of three. She always selects the highest setting; three bars.
However after sitting in her passenger seat recently, I have to agree with her. The panamera seats don't get much past warm. To compare, our cayenne and her bmw are uncomfortably Extra Warm beyond my tolerance.

So today I take my PTT in the dealer for inspection and service. Service manager calls, and tells me they "measured the temperature with a thermometer, and they are within spec". I'm like okay. Then I drive their cayenne loaner home tonite, and put on the seat on the highest setting and feel the cayenne seats are WAY warmer.

What gives?

I had the same issue on my 2012 Panamera. I have ordered a new S E hybrid so will see if that is still the same.

We have a 2011 Panamera 4 and a 2013 Cayenne S. The Cayenne heated seats are definitely warmer than the Pan's. On the Cayenne I can't leave it at high setting for too long because it gets too hot.

Very true ,same here

My 14 Pan S seats are definitely not as warm/hot in the highest setting as our cayenne. The cayenne's seats are HOT, compared to the panny.

My 911 seats and Panamera seem about the same. I always put on the low setting at the most. Both are MY14.

Of course it normally is not as cold in Texas

I think they just take too long to warm up.

my rental Cayennes were warmer than my 10' panny.
