Ac blowing warm sporadically then limp overheat tonight
Hey guys, here are the basics:
2014 335 xdrive (CPO) 42k miles MPPK MPE ———————- So for the last couple weeks, I noticed that sometimes when I turned my car on to idle, pumped the AC at full blast 60 degrees, while sitting there AC was blowing warm. As soon as I started driving, it would cool down, then if I idled again after coming to a stop, the air would blow cold! Thought nothing of it, scheduled my next oil change for 6/20 and also asked bmw here to diagnose this issue as well. All good Drove home tonight, idled for a little in my driveway and I got a yellow "drive moderately, car is hot" Idrive warning. So I drove a little around my neighborhood and the car was in limp mode. Got back to my garage pulling in and then got the red "engine overheated, shut car off" alert and I immediately did. So I'm thinking thermostat/water pump/ fan issue etc.... but would that be related to the AC blowing hot as well? Next question, I have roadside with the CPO, should I use it and tow to dealer? I'm thinking yes... Last question: I had to schedule my oil change due to lack of loaner availability which I requested....if a car is towed in through roadside, doesn't CPO guarantee a loaner? Let me know guys, thanks |

I would be willing to bet that the car would not engage the air conditioner if the engine temperature were too high already , hence the warning.. That would only generate more heat.. You are probably right in considering the fan/thermostat/water pump as the likely culprits..

What would be the point of a CPO really or having the emergency roadside assistance if emergency "warranty" work didn't guarantee another car? I have to call bmwna on this one I think, just to find out. Hopefully waterpumps and thermostats are in stock at my dealer!! |

Surely you've read the contract. BMWNA has nothing to do with the availability of loaners because it depends on how busy your dealer is.

Update: not a water pump not thermostat issue, dealer apparently had to "reprogram" something....then re-install the mppk.
This morning got the same exact symptoms, hot air blowing after car was running in idle for a couple minutes, when driving it felt like the car was in limp mode but no "check engine" messaging this time. Bringing it back to the dealer today again. |

The shop Forman came out to my car, sat in, saw the issues went through the service bulletin supposedly that was issued to correct this. So programming was to try first, now it seems like mechanically they will have to do water pump and thermostat.... a quick guess by him was it was "sticking". So loaner for a couple days and we'll see what happens! |

Is a weak A/C but no leak a precursor for a failing water pump and thermostat? |
