Did you ever have the dealer check out your heated seats? After the Arctic cold all through February I've been complaining about my seats being very slow to heat up too. My wife and daughter both have MINI Coopers. Their seats are hot by the time we get 2 blocks from the house. My GTI takes almost 5 minutes before I notice any warmth. I've seen some OBDeleven posts where people change the temp of just the back at setting 2. They have been keeping it below the level 3 setting though. I wonder about raising the temp of level 3 beyond the spec. Would it heat faster or at the same speed, but just get hotter at the end. The setting says you're adjusting the current. That makes me think more current = faster. The actual setting, however, says degrees C, so that wouldn't necessarily heat faster.
