Hello!
I recently purchased a 62-plate Fiat 500 TwinAir, and I have just been having a few issues with the stop start system. The vehicle is still under warranty (until September) and it is currently in the garage for the fourth time – being transported between the garage and Fiat, and no-one seems to be able to fix it.
I have been having a few issues with the start stop system, with it working very intermittently, and rarely staying cut out for more than 3 seconds before starting itself up again. However the main issue that I have been having is to do with the restart. When the engine is cut out, I will depress the clutch and the car will attempt to fire-up, however it fails (the start stop symbol will appear on the dash again), and I have to raise the clutch and depress again. This can take two or three attempts, and happens on average on a quarter of the times that I try to start the car up again. This can be very frustrating at traffic lights and junctions, with impatient cars behind.
Also, on one occasion, the vehicle did start up, however, it felt like it only fired on one cylinder. The car was running very roughly, but it had no power and would not drive. I had to turn the car off and restart.
Has anyone with any experience with Fiats or TwinAir engines got any ideas. The dealership have currently got the car, but it obviously never misfires in front of them (depite them acknowledging the StartStop system isn’t working as it should). The dealership have replaced the Battery Sensor which didn’t fix it, and they have just replaced the battery (which I cannot imagine is causing the issues, as they tested the battery and said it was fine). My limited mechanical knowledge suggests maybe an ignition coil issue or similar? Any advice gratefully received.
Thanks in advance
Adam
