OK I'm having a bit of trouble finding out the CEL on my 99 M coupe. First the tool tells me it's chart 1B and then code F1. The problem is there is no F1 in table 1B. However. there is a 1F, is that the same thing? I'd appreciate some feedback. TIA!

According to this Peake Code lookup (http://www.blek.com/peake.php) , it says "Misfire detected Cyl #4" for F1.
1F is "Ignition Coil Cyl #5"
Hope it helps?

According to my manual you should be using Chart 2 and that shows code F1 as "Misfire detected Cyl #4" just like Stinky said

Thanks a lot guys!
