  1. 159 Air Conditioning Compressor Connector Mystery

    Alfa 159, Brera & 946 Spider
    Hello everyone. Despite my best efforts to find a solution on this forum and the elsewhere on the internet, I've hit a brick wall with this one. My air con doesn't work and the fault has been diagnosed as my compressor needing to be replaced. So I provided my VIN number to several suppliers all...
  2. What's this Mystery Part???

    Alfa 147, 156 & GT
    I we have a 2010 147 2.0 Tspark. It broke a cam belt about 6 months ago and I've been slowly repairing it since then. It had bent valves, they're all replaced now and I've almost finished putting it all back together. I'd have to say it's gone better than I expected, I've found where everything...
  3. Mystery button

    Alfa 159, Brera & 946 Spider
    Have seen a lovey looking tbi Spider for sale on Autotrader with one little difference - a mystery button by the gear-lever. Anyone have any ideas what this could be for? Possibly some addition by a previous owner - switched electrical supply from 12v socket to some sort of accessory? Some sort...
  4. Mito Radiator Mystery

    Alfa MiTo
    I have a 2015 QV MiTo with 19,000 km. The outlet nozzle of the plastic coolant expansion tank failed. Heat around the nozzle has left it a discolored brown and the nozzle itself was cooked off. I never experienced abnormal temperatures, so I assume the plastic material of the tank at the...

    Finally got around to replacing the clips holding the fuel tank heat shield in place. Mine had totally rusted away. According to Alfa parts list the don't exist but they are only a bog standard clevis clip so easy to get hold of.

  8. Brera aircon mystery - detectives wanted

    Alfa 159, Brera & 946 Spider
    I have a mystery fault with the aircon which I’m hoping someone may be able to help with. The system works for a few weeks and then stops due to low pressure, so the gas is presumably getting out somewhere. What is odd though is that it has been pressure tested numerous times and always holds...

    Need to start off by saying I know little about cars. My rear screen washer currently isn’t working, looked at the engine to see if anything is not connected and found this close to the screen wash. Where is this supposed to be connected to? Any help would be appreciated.

    Ok this has completely flummoxed me. Just put my GTV on the road today after buying it a few weeks ago. There was evidence of water ingress in the bottom of the boot when I bought it (the carpet was a bit darker but was dry at the time). The car has been sat outside in the rain a few times...
  17. Mystery 156 cable in the front end

    Alfa 147, 156 & GT
    Anyone know what this cable is for? On my car it goes nowhere, and I wonder if its a sensor cable? Inner cables are black and white, location is behind the bumper. All assistance is appreciated. I have an airbag warning light showing, I hope its not a front sensor that isnt there.

    Alfa 159, Brera & 946 Spider
    Does anyone know where this rattle is from on my Brera? On the video you can hear the rattle on ignition. Ignore the loud vibrating noise either side of the ignition (that's the sound system / CD rotating). Listen out for the high-pitched rattle when I push the start / stop button. It makes...

    Alfa 147, 156 & GT
    Just wondering if anyone's got any pointers before I go down the searching for a broken cable route... Bought my GT earlier in the year and the air con didn't work. I found a receipt from a garage saying there was a hole in the condenser from mid 2015 so it hadn't worked for at least two years...
