Hi all,
My 2012 cooper S clubbie has gone into limp mode and the F2 fuse keeps blowing.
Can someone tell me what this fuse controls? ( it is under the hood)
My clubbie has 50k on it.
If someone could point me in the right direction like" the F2 fuse controls x,y and z and it's probably Z" that would be helpful.
Car starts fine with no rough idle.
Thanks,

 

F02 in the engine bay fuse box is a 25A ECU circuit

 

Unfortunately, the factory wiring diagrams just show this as supplying power to the DME - among many other fuses that serve the same "general purpose." So I can't give you a detailed "x, y, z" description.
Have you scanned for error codes with a BMW/Mini specific scan tool? I'm sure there's something in there.

 

So I bought a fixd scan gauge and it advertised that it read all BMW codes but it just reads the same generic code as my cheap reader I already have.
Sending it back and going to buy a gauge that reads BMW codes.

 

Heres what I could find on it. F02 powers pins 6 and 18 for terminal 87, which then power a bunch of sensors. But so does fuse 3 and 4 from what it looks like. But once you get a scanner that can read the car it should shed some light on whats going on.

 

OK, so I got a foxwell scanner and it seems I have a short somewhere, perhaps someone in the group has seen this and send me in the right direction to start with.
I have no idea really where to begin.
Here are the codes I got:
Engine electronics DMV
2C3E Quantity contropl valva,activation. Short circuit to ground or line disconnection
2D0C Oxy sensor heating before catalytic converter, activation. Short circuit to GRD.
2D10 Oxy sensor heating after catalytic converter, activation. Short circuit to GRD.
3400 Engine oil pressure control valve,activation. Short circuit to ground.
348F Map thermostat,activation. Short circuit to GRD.

Stability system EBC_450 ABS-DSC
5E30 DSC control unit,voltage fault. undervoltage
5E31 DSC control unit fault,voltage fault, undervoltage
5E5C DSC brake pad wear indicator,front brake pad
5E5D DSC brake pad wear indicator, rear brake pad

switch centre,steering colum SZL
9E31 SZL undervoltage

combox mutimedia CBX media
A8F9 CBX-Media software reset
A900 USB port,shut down due to overlaoding.


So there it is and I hope someone else has encountered this and can steer me in the right direction.
Only thing that had happened that could be a cause was that I was having a bit of trouble getting unstuck in my driveway and rocking car back and forth but it was not extreme and I did not get the check engine light until a few days later. As far as the undervoltage check, I did check the voltage live with the scanner and it was putting out 14.2 V . Maybe the battery has run down as the car has been sitting for a while?

Thanks for the link Njar,
the codes came up with this service plan:
2C3E- Check the lines and plug connections between the following components:
DME
Quantity control valve
- Replace high pressure pump.

2D0C- Eliminate secondary faults, faults for the following components or functions:
Check terminal 15 N_1 lines and plug connections between following components:
DME
Oxygen sensor before catalytic converter
- Check oxygen sensor before catalytic converter.
- Replace oxygen sensor before catalytic converter.

2D10- Eliminate secondary faults, faults for the following components or functions:
Check terminal 15 N_1 lines and plug connections between following components:
DME
Oxygen sensor before catalytic converter
- Check oxygen sensor after catalytic converter.
- Replace oxygen sensor after catalytic converter.

3400-Check the lines and plug connections between the following components:
DME
Oil pressure regulating valve
- Replace oil pressure control valve

348F-Check wiring harness between DME and map thermostat.
- Replace map thermostat.

So from all these it would seem to me that it probably is the high pressure furl pump, but what do I know?
maybe someone who has replaced the HPFP can tell me if they saw all these other codes too. Or if someone can say if the map thermostat, oil pressure control valve and O2 sensors are also prone to failure.
Thanks,

 

A little more info:
when I look at the high pressure live through the scanner it starts at 2.00 Mpa then drops to .60 when I give it a rev up.
nominal is .60

 

HPFP output should go up as you rev, not down

 

after much frustration I finally took my mini to the dealer and they pinged me $340.00 to diagnose the Oil control solenoid needs to be replaced.
has anyone done this? any special tools needed? sump need to come off?
Shop wants a $1050.00 for this.

 

HI
I have the same problem, the fuse is blowout F2, you fixed problem in the car?
