BMW 318iS Check engine light illuminates and I have no speed control. While driving recently My check engine light went out and my cruise control returned, satisfied I turned cruise control back off. My Check Engine light relit and I immediately tried to work my cruise control and not to my surprise it was again unusable.

I would appreciate any advice or technical knowledge. Thanks.

I was reading another persons forum post and they stated that under the dash there is a white switch, is it S28?
Also would this effect the check engine light?

Get the codes checked, report back here and we'll help you fix whatever is indicated, then worry about the cruise control if it isn't fixed with whatever threw the code(s). That's what OBDI and II is for...on-board diagnostics.
