  1. No clicking when testing the lambda heaters in MES

    Alfa 147, 156 & GT
    Hi everyone I am having issues with my car throwing lambda codes, the codes are P0161 and P0141. I plugged it in and checked with MultiECUScan and when testing the heaters for the lambdas I didn't hear a single click. Anyone know why?
  2. Testing blinkers with airbag off?

    Alfa 147, 156 & GT
    Hi, I'm trying to figure out where the problem is with my wife's Alfa's blinkers. Started as a once-in-a-while not working problem, now if I flip the turn signal stalk up and down rapidly, they'll work for a bit, and then stop again. I'd like to test things without having to reconnect the...

    Alfa GTV & 916 Spider
    Does anyone know how to test the heater resistor (pictured below) with a multimeter? I've got the resistances from this thread but am unsure how to measure using a multimeter.

  5. Testing Fuel Injector

    Alfa 147, 156 & GT
    Hi. I need some help AGAIN. Having got my car back after the ECU and bad wiring were replaced, I have a misfiring injector. My mechanic put injector cleaner in before I left, but it has not helped after about 250 miles. He says we have to arrange to have the injectors taken out and sent for...
  6. Alfa 156 1.8TS FuelRail testing port type?

    Alfa 147, 156 & GT
    Hi Alfa fellows, My 156 1.8TS runs weird on start-up at the first time of the day - something like can't suck the gasoline from fuel tank. My first step is to check the fuel pressure is stable or not, but I can not recognize the testing port as the picture below (size is different...

    Alfa Giulietta
    Hi, Quick question - Has anyone used a Vacuum gauge to test Vacuum on a Giulietta MA. If so could you point me to where you attached the gauge for an accurate reading please? Only sensible line I can see is the breather from turbo inlet pipe to inlet manifold but unsure if disconnected it...

  9. Testing Multiplexed MultiECUScan in London

    Alfa 159, Brera & 946 Spider
    Hi All, I've recently purchased the multiplexed version of the MultiECUScan software- it means no adaptors (except for early 3pins). I've tried it on my 156, and it worked fine. I also tried it on my Brera, but doesn't seem to connect; now this could be because of the fault - Vehicle...

    So I use original BOSE speakers,woofer etc in Alfa GT. I have the next problem that I only notice when I listen to this song: when the song comes to 01:00 the right side speaker begins to be awkward,twitching something like buzzing. The sound is increased to 18(25 is max). I tried many other...
  11. Testing a used alternator?

    Engines (TS, JTS, JTD & V6)
    I have a used (assumed good) alternator to fit to my 916 Spider Twin Spark. Before fitting it (which is obviously a significant amount of work) what tests can I run on the alternator to check it is healthy? All advice welcome!

  14. Solonoids testing? Functions?

    Alfa 147, 156 & GT
    Solenoid testing ? You test on the bench or just by unplugging on the actuator? So i wonder what you do when or if there is no activation to the solenoid? I see the EV3 and EV4 work (1-2 and 5-R). I have put another actuator assembly in which has a good Reverse and the clutch operation but...
  15. Youtuber testing Giulia Super...

    Alfa Giulia
    Saw this so thought I'd share on here. It's the 2.2 diesel, and the comments all sound familiar with my experiences from driving the diesel at Millbrook.

  17. I need to test my 159 3.2 ECU

    Alfa 159, Brera & 946 Spider
    My 2005 3.2 159 is playing up. Most of the time it starts fine but maybe once in every 10-15 attempts it turns over but does not fire. If the car's warm then it may fire but struggles to idle and quickly stalls. Reseting the ECU (disconnecting the battery for 45 mins) has fixed it every time so...

    General Motoring Discussion
    Non, no, not me :) Do you remember I posted a video of a chap that reviewed the Alfetta GTV6 recently? (If not, don't worry, I will find the link for you later). Now he has got his paws on a road going version of the Renault 5 Turbo 2, the mid-engined hairy beast from the 80s...

    I have had haphazard P0240 error Turbo/Supercharger Boost Sensor B circuit Range/Performance only when I floor the car. I have removed the MAP sensor from the engine (clip still attached) and with ignition on (engine not running) I have 1.54V from signal wirer. The ECU is sending 5.10 V from...
  20. Diagnostic and testing tools

    South Africa
    I am starting this thread so that we can all get our minds together on which tools for diagnostics or testing are best. I have just discovered that my Gunsons gas tester for exhaust gas analysis would be useless on my GTV because the error (0.5%) is larger than the intended CO evels that I am...
