2005 R53 JCW - Owned less than a week

All, I have this recurring SES light. I cannot remember what the OBDII code is but it means lean condition. I was told by the dealership and from my research that when you are lean on the post Cat 02 sensor that means an air leak. I have since replaced the green gasket that I believe was my air leak. At what point should I replace the 02 Sensor? I am ready to buy one.
Thanks in advance!
PS. I set a personal best during a commute up the canyons! This car was a blast to throw around the corners at faster than legal speeds
Most recent check engine light.

You have not given enough info to narrow it down.
It may be the downstream O2 sensor, but may be other issues also.
The MAF may be dirty or toast.
The blow off valve may be stuck open, or the vacuum hose on it may be cracked or off.
Other hoses may be cracked or off.
The spark plugs may need changing.
The fuel filler cap gasket (o-ring) may be cracked or broken, or just not on tight. (not a lean thing, but common problem)
Keep us posted and check the simple things before buying a down stream O2 sensor, if you need one, try to find an OEM one from places like Amazon (cheaper). The cheap ones never work well, or for long and BMW sensors (Bosch) are more accurate, in my experience.

When you say blow-off valve...do you mean bypass valve since mine is supercharged?
#104
Yes, the bypass valve pops off, but instead of throwing the pressure to the outside, it goes back into the intake system. If it does not seal completely, it will throw more air into the system and cause a lean condition.
Things that can go wrong with this device are:
cracked or off vacuum hose
stuck butterfly shaft
gummed up
broken vacuum pot
broken or weak spring
leaking o-ring

I will use this thread to trouble shoot.
How to get to my boost return valve? Post #3 contains good information. I will get at it from the top of the engine.

I could really use some help. I don't know how to clear the airbag light. I have tried 3 or 4 different versions of the INPA software but can never access the airbag module. Any ideas? Local shop quoted me 2 hours labor as they have never done it before. What software can reset the light?
Below is the software I have tried. (Except ISTA-D & Joseph Jones)
Thank you in advance!

Any other ideas? Should I just buy the airbag reset tool from amazon?

My current update is everything is complete. I stitched my seat back together. Fixed a faulty ABS Sensor. Check Engine Light Turned off. Now it is just the last Airbag light.

And I loved it! It was so much easier than trying to use the laptop and eBay software. I can't tell you how many hours and software types i used. The code reader was instant and easy. Wish I never spent money on the cable.

Eddie. The OBDII Reader is very helpful but kind of slow. I do not know if this could replace a laptop with software (INPA or ISTA-D or NCS Expert). For my purposes, this is perfect and so simple to use. I have not played with a manual or anything, but there are many different screens with live data for monitoring purposes.
If someone has a specific question, I could test that. Just let me know.
Software Version. (Not the most current)

Sample Error Code. (Looks like I might need that O2 Sensor)

I think this would be perfect for me. I have plans to install race seats in my MINI. To do this I plan to buy a set of MINI seats and put the pressure pad into the passenger seat. I will need this tool to reset the seat belt warning. Hopefully, I won’t need to totally recode everything when I do this.
Thanks for sharing and offering to help.

All.
Thank you so very much for all the help the past few months! I could never have repaired my car without this forum. A Mini is a blast to own and drive. I got comments everywhere I went. With mix emotions, this past week I sold my 2005 JCW.
It was quite an experience to repair and get the vehicle road worthy again! Best of luck in all your endeavors!
