This is normal
Hey guys,
I had this same "issue" and brought to my dealer to diagnose. I wasn't sure if this was actually a problem because many high performance cars have this feature built in to their computer programming, the point is to try and warm the engine up as quickly as possible before driving. Enjoy the beast in all it's glory (even it's rough starts) cheers! |

Ok so I have determined the issue with mine. Apparently with the newest DME software available at dealership has an issue with catless downpipes even with JB4 turned on. The DME's can see cat efficiency immediately even with JB4 clearing fault memory on every start-up, so the fault would come back in less than a minute. Installed factory cats back on vehicle, problem solved immediately. I then drove it for 2 weeks, never once did the idle fluctuate or engine stall during cold start. I miss the sound and throttle response with the catless and I've found a solution for less than $100. All you need is 2 of these,http://www.ebay.com/itm/Catted-O2-ox...ZYR88f&vxp=mtr They fit just using the straight part. Not so sure what the deal is with the stock catted cars though. But mine is fixed!!

Did you reset all engine adaptation values after you installed the catted 02 sensor spacers? Because as soon as I removed the catless downpipes and reinstalled the OEM cats, the problem was immediately resolved. Thats why I decided to try the catted spacers and still dont have any issues. But I did reset adaption values after I installed them.

I have a friend that works at a dealership, used BMW ISTA software. Maybe you can take it to a dealership and have them do it for you, only takes about 15 minutes to do. It will idle rough for a few minutes afterwards because its recalibrating everything. Hope this helps.

The video's that got posted are unavailable, could "Can-am" or "BMWadrenaline" repost their video? I'll try to reproduce mine tomorrow morning (cold-start) and will post if it happens again. Thanks guys! |

Looks like a software update solved it
BMW performed a software engine update (under warranty). Only had the chance to test it once (with cold engine), but they think it should be solved. Will keep you posted.
