All, after taking my 545i in to the dealer, they told me that it was one of my coil packs. My SA said that I could probably fix this but required moving a lot of stuff out of the way first. Due to my schedule and the need for me to replace the spark plugs in the next 10,000 miles. I decided to go ahead and have them do it. Ultimately it cost me $680 (which killed me) but my car is running great again! However, today neither my seat heater or steering wheel heater are working. I assume the dealer blew a fuse or didn't connect something back. Anybody know so I don't have to drive back to the dealer?

THANKS!

 

If the coil pack was faulty, I surprised that your CEL did not come on. You're should check the fuse and connections.

 

Yes...I meant to add that the CEL did come on on Friday on my way home from work and stayed on. It has an Emission fault read out.
