P codes are worthless. As is any code, without a proper fault description. Get a real scanner that is BMW specific, read the code, and post it, with the description of the fault code.

And don't ever take your BMW to a regular Joe Blow mechanic shop. There's a reason they couldn't find anything wrong. Because they're not well experienced with BMW's.

Error Code P2098 is defined as Post Catalyst Fuel Trim System Too Lean Bank 2, a problem usually caused by issues in the catalytic converter or by an exhaust leak. This code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, especially vehicles made since 1996 up to present.

Generic answer for generic question. Hope that helps.
