Oh and PLEASE LEAVE YOUR ENGINE COVER OFF.

nearly all of the problems that plague the 50i are due to heat build-up and the engine cover is not helping. You don't need that silly thing, THROW IT AWAY

and if you ever decide you want to work on it yourself, let me know. I have designed my own catch-can setup the does away with most of those BS CCV tubes and increases the Crankcase vacuum to a proper level for increased performance. I can help if you want to tackle it yourself. FYI, if you replace the CCV tubes yourself, it will only cost you 150 dollars in parts...you can save a TON if you do it yourself.

Ive got 144,000 miles on mine, you can too

Welcome. Interested to hear what you've done.

Interesting advice on the engine cover- never thought of that.

Update here...spark plugs were changed and so far the check engine light hasn’t returned.

The shop also found that the dealership had failed to replace 3 screws and left a fourth one loose, plus the intake charge pipe on one side was loose. They fixed all that. Word to the wise to anyone considering Reeves BMW in Tampa who wanted to replace both pipes and the crankcase vent tubes for $2k.
