    STOCK = 30FF, JB4 NO 30FF

    Hello all, So after ignoring all of your advice about not buying a 335I, I went and did it. Anyways, I have an interesting problem. When I set the JB4 Map to 0 and try and do a 3rd gear pull, the CEL comes on, with the error 30FF If I then put Map 1 back on, I can WOT without any engine...
