I have a 2018 S560 and driving from cold start, noticed the steering wheel heat didn't come on for about 10 minutes.Then it was never really warm as my old 2009 Jaguar VDP which kicked in immediately and very warm. It was -3C outside. Is the heating element wearing down?

Thank you for your input

For heated seats, heated steering wheel, front reading lights…. I like that feature….👍
