    My car makes a sound like a vacuum cleaner after it is turned off, keys out of the ignition and door locked, why?
    It is not overheating according to the temperature gage it is right where it should be and I already had the temperature gage replaced a year or so ago.

      It sounds like the fans are on to cool down the engine just for a min or two.
      Is a normal operation of your vehicle.

      Sounds like fuel pump, which are generally rated at 50k miles. Modern fuel pumps are inside the gas tank and require that you drop the whole tank to replace the pump. Also check your battery terminals. they may be loose and not allowing things to go.

    Engine makes sound of deflating balloon when shut off
    I have a sound coming from the back (near Firewall) of the engine when I turn the car off, which sounds like air escaping from an untied balloon. Any ideas?

      make sure the vacuum hose on the fuel pressure regulator is on, on the bottom of the fuel pressure regulator on the fuel rail, its a small black vacuum line that hooks to the nipple of the regulator. OR it might be the refrigerant (A/C) pressurizing or something. My MCS does not do this, but my other vehicles do this after driving w/ the A/C on. The hotter the day, the longer it "hisses" for.

      Try running w/o the A/C on (even better w/ the whole auto a/c system shut down), and see if your car hisses at you after a drive.


      I might be the supercharger, i blieve the S has one equiped. Whether it's somehow depressurizing or coasting to a stop, you can hear it because the engine is off.

      By the way, welcome to the club, you are not alone

      Thanks for the help. I understand there may have been an issue with some of the fuel pumps on Minis, so I'll start with the vacuum hose on the FPR. I'll let you know what the outcome is.

    I just bought a 2006 Cooper S and the fuel consumption is extremely high, around 18L/100Km, is what a Hummer burns. I changed both O2 sensors because the scanner showed O2 sensor error, but there was no improvement. I have read about reasons that could explain this, ...

      Replace the Cooling Fan Switching Unit which is the entire fan assembly. Probability here is almost 100%.

    I cleared the code and the check engine light was off for about a week. Now it's back on. looks like it's the downstream O2 sensor. I saw a TSB listed about this code but couldn't read the complete message. I have a new sensor to put in. Guess the best thing is to ...

      P0136 = Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 2)
      Possible symptoms = Poor fuel mileage, possible misfire, depending on O2 sensor position when sticking.

      A code P0136 may mean that one or more of the following has happened:

      Faulty O2 sensor leak in exhaust close to O2 sensor
      Short to voltage on O2 signal circuit
      Open in circuit resistance caused by corrosion in connector

      Possible Solutions:
      Replace the second oxygen sensor on bank 1
      Repair open or short in signal circuit
      Clean corrosion from connector

      You have to use a scan tool to verify the stored trouble code and to reset/delete the stored trouble code.

    What is wrong when the motor sounds like tactactactac
    the vehicle mileage is 21000. I can hear the noise always either cold or warm but most when cold. I care it has nothing to do with pistons.

      I heard there were some issues with the timing chain on some of the Mini Cooper engines. Check TSBs for engine noise.

      too many causes for this light to come on. have it scanned for the particular code that it is sending please and post them here so we can help you more. advance auto or auto zone may have the correct scanner for this model, if not you may have to call a few shops and pay to have it scanned. it is alot cheaper than just throwing money and guessing at what is the cause.

      You should diagnose your vehicle first with a scan tool to determine what the stored trouble code is. The extracted trouble code will help you.
    • yboy82

      You post the extracted trouble code here. If you don't have any scan tool you can visit Autozone for free diagnostic.
