S500 takes a while to 'warm up'
 

Yeah, basically my car now days takes a while to 'warm up' so I have to keep it on for 2-3 minutes before I drive it or else if I drive it right when I start it up, it takes forever to accelerate until 40 seconds later etc.

What do I need to do to have this fixed?

Thanks

Any codes?
 

Have you checked the computer for codes? It sounds like something would have to be "wrong" enough to register a fault code if this problem is occurring.

any check engine lights?
