It's 70 degrees outside and my 2011 MCS with 11600 miles is giving me the half yellow CEL for the first time ever. I've read that the code relates to the high-pressure fuel pump. The engine doesn't sound abnormal, idles fine, and does not give off any suspicious odors. I drove it under 30mph around the block and it seems to be fine. I'm afraid to drive it any faster or any further, though. The half yellow CEL only appears on the tach and it appears in "CHECK-INFO", but the CEL on the large speedometer is not on. Some background: I have not driven it for 36 hours, give or take, and temperatures dipped down to the low 50s in the past 2 days. I always fill up with 91 and the dealership changed the oil 600 miles ago.
P10D0 is Charge air temperature sensor, plausability, cold start: Temperature too high What that really means..heh, beats me. But it does get you further into diagnosing the issue. We have the full set of MINI OBD Codes here in the library - ECU Codes Chart - 2nd Generation MINI - Library
Thanks, Nathan! I was just going by what I was told at AutoZone. I tried to erase the code but it persists. Maybe I was doing it wrong. Is there a way to clear the fault codes without a scanner? (Long story, but I no longer have the scanner) jbewley, the light looks like this:
Don't know, Metalman. This 2011 is my first one. I commend MINI for distinguishing between minor and major engine malfunctions, though. I cracked and bought my own OBD II scanner. I erased the code, properly this time, and the CEL, half yellow or otherwise, has not not appeared since.:fingerscrossed: My MCS runs fine. Before I erased the code, I fiddled the dash computer. I found a "CC-ID 029" in CHECK-INFO. According to my research, this code indicates a failed HPFP. Has anyone ever heard of this?
HPFP = High Pressure Fuel Pump..... Get it in for warranty..... But unfortunately you don't want to erase the fault code. Your dealer will need the fault for warranty repair. This is a known MINI issue. MINI has extended the warranty coverage on this item..... If you live in the US........ EDIT: but only for 2007, 2008 & 2009...... http://www.motoringalliance.com/forums/cooper-s/4059-r56-high-pressure-fuel-pump-warranty-extension.html#axzz1sJwwe0qH
Well crap! This CEL just popped up! We've already had to replace the pump a year ago in Albequerque! And MINI of Dallas can't see us until Tuesday.
I had the same code pop up. Dealer said it was not HPFP. After I ran the existing fuel out, got fresh gas the error cleared itself in bout 150 miles. Hasn't been back in 3000 miles I guess.
I got the half engine CEL when I had ice in my intake but that obviously wouldn't be the problem. If it comes back, drive it to the dealership. If I remember correctly it says it's safe to drive just get it checked out asap.
