Hey all. I have a 2010 MINI Cooper Clubman 2dr Cpe. I have had no issues with it since picking it up earlier this year. This is my commuter car for work. Setting off for work the other morning it started to miss. I got home and plugged into it to pull codes.

I got a slew of them. Not worried about some of them as I knew about them and plan on fixing them this spring. The misfire and o2 sensor codes are the ones in question. Not sure if the misfire is causing the O2 codes hence why i am posting here. First mini i have had and not sure if there is a domino effect. My plan is to dig into the misfire first and then O2. Wanted to get others opinions on if thats how I should proceed or change it up.

Let me know thoughts! Thanks in advance!

You have a lot of codes, which sometimes means a bad battery or alternator. Check battery voltage with car off and running (charging).

 

This is a good code resource:
https://bmwfault.codes

I would plan replacing the O2 sensor, plugs, and maybe coils. While you wait on replacing those parts, clear all codes and see if any come back, then address those.

 

This all started after the battery died in the car after it being below 0 for over a week. I didn't think about putting that in the original post. I didn't realize that would be causing these types of issues. I charged the battery outside of the car and it got back to full charge and stayed there for a few days before putting it back in. It has stay charged and shows that it is charging while the car is running. 12v sitting and 14v when running. Is there a process to swapping batteries out in Mini's that I missed other than just swapping?

Another weird thing that started after that is the windows don't go up to seal the doors once closed. They bump down when you open the door like normal, but don't go back up that small bump to seal.

 

Sounds good. I will plan on that route and seeing what I get. Thanks!

 

When the car is off, the battery voltage should be 12.4 to 12.7V.

For optimal battery lifetime and performance, you should always register a replacement battery with a scan tool.

You can fix this issue by initializing the window regulators with a scan tool. This may also be possibly done using a manual procedure.

 

Sorry, I was rounding on the battery values. I will pop out there at lunch with my meter and get actual values.

What scan tool or app is best for doing this work? All I have right now is an old Bluetooth ODB2 adapter for pulling codes.

 

There are many options and price ranges.
I opted for LAUNCH X431 Elite 2.0 PRO for BMW. It has a lot of features but it's not top of line by any means. I paid $120 for it.

You may want to try this manual window initialization first.

Manual window regulator initialization
Procedure done at switch for affected door.

Prep / requirements
Key ON / “Terminal R” (accessory/ignition on), engine can be off
Doors closed
Good battery voltage (hook up a charger if the battery is weak)

1) Erase old initialization
Run the window fully down (use the “auto/down” detent if your switch has it).
Keep holding DOWN for 15–20 seconds after it’s fully open.
(During this phase, one-touch and anti-trap can be inactive, so keep hands/arms clear of the glass.)

2) Re-initialize (teach the end stops)
Run the window fully up.
When it reaches the top, release, then pull UP again for ~1 second (same “close” detent).
Run the window fully down.
When it reaches the bottom, release, then press DOWN again for ~1 second.
Run the window fully up again and once it stops, release, then pull UP again for ~1 second.

3) Verify
One-touch up/down works
No immediate “reverse” (anti-trap false trigger)
If your car has frameless glass, confirm the small “dip” when opening the door works normally

 

Thank you so much! That got my window working like it should again! WOOT!

 

Question, for ordering the new coil and 02 sensor, any brand I should go with or stay away from? Don't want to spend money on junk but also don't need and race parts. 🤣

 

I wouldn't like to see you buy parts unnecessarily.

Did you clear all fault codes and then drive the car to see which ones return as hard fault codes?

After this^ test, if the cylinder 1 misfire code returns, you can swap coil 1 with one of the other coils to see if the misfire code moves with coil 1.

Chasing hard fault codes and doing logical diagnostics are always the best option before replacing parts.

 

I did clear the codes and they came back the same.

I will move the coil to another cylinder and see if it follows. I will need to get some parts ready soon so I can get the beast back on the road. Having to drive my truck to work is not fun on gas! 😬

 

If so, an underlying voltage issue may be causing of most or all of those fault codes.

 

Forgot to respond to this.

Oof... any thoughts on where to start the gremlin hunt? Like I said before, everything ran great before the battery died and I pulled it out to recharge it. After doing that I drove for a week before it started this non-sense. It was on the first really cold day we had. -10 or so I think it was. Started off driving fine that morning, and after 30 mins of runtime, it started to misfire.

If you know where I should start, that would be great appreciated. Never worked on these before. Just need to know what the best starting point would be and I can run from there.

​​​​​​​Thanks!

 

Start here -> Verify that your code reader is capable of clearing a fault code.

 

After clearing the codes, this is the output I got. It was after getting here, I started the car back up, drove down the street and back that I got the output I put in the original post for this thread.

The misfire and O2 sensor codes are now gone along with many others. What's remains are only airbag and an FRM code related to window.

Any engine performance issues?

 

The most recent post that only has SRS codes was after I cleared the codes. After driving it down the road and then back to the house, it started misfiring while on the test drive, is when I pulled the codes that I posted in the original post. So after clearing all codes, then a test drive with issues, I pulled that list of all those codes it was throwing with the misfire and O2 sensor errors. So once cleared, the error codes came back showing the misfire and the O2 sensor issue.

 

So all codes have cleared except SRS, misfire cylinder 1, and O2 sensor?

 

No, they came back.

During the test drive, the car started to misfire again. I checked the codes and they were back.

 

If you monitor battery voltage with engine running and engine off, what do you observe? Voltage swings, low voltage, or high voltage?

 

I will try that and see what I get and report back. Thanks!

 

OK, so I went out to work on the Mini. Battery was toast again. I replaced the battery with a brand new. Then registered the new battery. The car does not run as rough and is drivable but constantly stumbling. I checked error codes. 95% of them are all gone. The only codes I have now are in the image below. Looks like still having issues with the ignition coil.

 

Possibilities to check in this order:
Cylinder 1 ignition coil
Cylinder 1 spark plug
Cylinder 1 fuel Injector
Vacuum leak
Cylinder 1 low compression

 

Thanks! I will run through this list over the weekend! Thank you again for all the insight!
