AC Shutdown again
2011 BMW Z4 35i ...
I have an appointment scheduled for 'Chassis Stabiiization Malfunction' issue for tomorrow 07/16. This evening when I started the car, AC didn't work. I called Service Manager and dropped off the car in that state. Service Manager verified AC is not working. This happened a few times in the past. I read several posts here, posted myself about this issue. For 'Engine Malfunction' after 3 times, service center replaced some fuel pump or something. After that I didn't notice any AC issues until today. Sent a msg to BMW NA from here and also called them. I was advised to work with the service manager ! They also told me to think over and call them back if I know of any resolution ! Any 2013 or 2014 Z4s have this infamous issue ? |

Read the entire thread, I 'invented' the T-Fix. No prbs if you do that. Best solution so far unless/until BMW actually fixes this prb.

Re engine malfunction, I assume that is another issue vs the HVAC prb. |

I had that happen... During a road trip. Unfortunately, it wasn't 'my' dealer. After they did a module reset, it worked again. We wanted to get back on the road, so weren't interested too much in them spending a whole lot of time.

What is a "module" reset and how is it performed?
Is that like rebooting a certain part of the car through the software using a diagnostic tool hooked up to the car? If so, a part of me longs for the "analog" days when HVAC was a simple on/off button for the compressor, a dial for mixing hot and cold air and a 4 position switch for fan speed. |

I still don't understand what BMW NA meant by 'how do you want to resolve ?', 'Think about it and give us a call back'. I asked them if they can send their tech, have their tech call the local tech ... their response, 'if you want the vehicle fixed, work with the service manager. He knows how to reach out to us. If you want to resolve another way, give us a call'. But wouldn't tell me what are the other ways. So, once every two weeks I have to go and work with the service manager. Regarding lemon, they said it depends on state laws.

I've had the AC issue occur 3x since taking delivery May 2012.
Twice before dealer "conducted repair" (two months into ownership) and once afterwards (more than year). In all cases the car resumed normal operations the next day. Not sure about your particular state, but I did lookup NJ lemon laws (where I bought mine). Needs to be a malfunction effecting safety or drivability, or significantly degrades resale value, which cannot be repaired by a certified shop after 3 occurrences. You also have to be within 1 year of a "standard" manufacturer warranty, or either 2 or 3 years of an "extended warranty". It's been a few months since I've read it (problem hasn't come up in a while), but the NJ lemon law paperwork was included with the sales paperwork. I'm sure it's easily located online for most everyone's state. So yeah... I recommend searching for your state's lemon laws, and documenting! Take video and tell the dealer about each occurrence if you're considering using the lemon law. |

Call them back and say "I would like you to resolve this by buying back the car from me" A friend in CA who got his 335 and 535 lemoned for turbo issues mentioned to me that they prorated the buyback based on when the issue first occurred. i.e. if it happened a month or two after you bought it, you get almost all your money back. |

Interesting thread, both of them. I had this happen to me 2 weeks ago during autox. I assumed it was an overheat issue as we ran consecutive runs, about 10 total in 90 degree weather when the ac failed.
I assumed it was over heating because I can feel the faintest heat coming from the vents. After numerous restarts attempts it still did not work. After my last run I popped open the hood to help her cool down. You could see the heat rushing out, the "waves" . It really worked with in 30 min. Ac turned on with out any problem. Just curious how many other members had ac fail during spirited driving, hot weather- long drives. Maybe this is 2 events? Some are due to over heat and others are the module? Just a thought.... |

Good news ... I just checked with Service Manager. It seems the AC is still not working. In the past the AC worked after turning off the car for 30mnts. They found some codes stored in the car ! Right now, they are working on 'Chassis Stabilization Malfunction' issue. Maybe both the issues are connected. We will know more later in the day.
