Hello Everyone,

I just bought a used 2014 Mini Countryman Base (50k miles) for my daughter to drive to college and work with. Had it less that 3 weeks and it threw a bunch of codes and lights (CEL) was in limp mode, etc.. I pulled the following codes and know what they "mean" but not sure how to correct them:

P0111
U114B
U115B
U115E

The car would just turn over and not start several times. At one point, without my foot on the brake, the car still turned over, but no start. That was scary because it should not have cranked with my foot not being on the brake. After looking and playing with some wiring under hood and checking fuses (one may have not been in place fully) the car started when turning over (CELs showing). Not in limp mode, I quickly took it to the Mini dealer.

The P0111 = IAT, but it doesn't seem this vehicle has a specific IAT? It is a part of the MAP sensor? Hence, where is this located? On the side of the manifold? Any pictures for it. I ordered a Bosch MAP sensor to try and replace it and hope is solves the problems.

After getting the car to the Mini Dealer they did a scope for $170 and pulled like a page full of "their" codes they say. See below picture/list I didn't really learn anything more than I all ready know from my code scanner with the P and U codes it gave. The adviser says they're all due to the P0111 code IAT and wanted $500 in parts/labor to replace it. So I'm doing it myself the MAP sensor. Does this sound correct? Any idea on these other "communications codes"?

 

Perhaps I posted this technical issue in the wrong sub-forum?

Anyone have any information on the MAP sensor being the root cause and where it is located and how difficult to replace?

 

most of the codes seem related to a weak battery. either replace it or get it checked. then erase the codes and see if anything pops back. as for the map sensor, it is located on the right of the intake manifold.

here are some helpful sites:

Thanks for those suggestions, I am a bit familiar with the RealOEM site.

Has anyone had any issue with the fuse box and relays in the engine compartment. Perhaps dumb luck, but I think the main R1 relay or the connection is problematic and intermittent. I clear all the codes and the machine runs great but can move this relay and hear some clicking and get all sorts of U114/U115 codes and lights thrown and car cranks but no start. I don't think the issue is the battery at all, but the issue surely points to low voltage and battery, but that is if everything else is good and nothing wrong. Are these Mini's known and **** to connection issues and fuse box/relay issues?

Found this video that seems to show what I suspect:

 

it is a rare occasion for them to go bad, but more probable if you have a leaky sunroof. there is another fuse box behind the passenger kick panel. As for R1 relay, you can certainly swap it with the ones above it and try it out. R1, as said in the video, is responsible to power the DME/ECU. so if it is unplugged, the car will crank but not start and you'll have U codes and wont actually be able to communicate with the ECU.

 

It doesn't have a sunroof. Thanks for letting me know about another fuse panel behind the passenger kick panel. Yes, it seems that there are 3 relays in the engine compartment and they are all the same. The R1 relay connection didn't seem stable. So I slightly bent the relay tabs to make a better fit. I couldn't see anything with the female tabs in the block. I will try to swap the relay for the fan (top one I believe) with the bottom (R1) relay to see if that is any better. The problem is certainly intermittent and seems linked to the R1 location.
