Everything was fine so far. But all of a sudden, your Seat Mii doesn't start more or barely start. What is annoying is that we do not necessarily really understand where the dysfunction comes from. Since you must have missed your appointment, take a few minutes to understand the dysfunction. We will see through this file what will be the most usual situations and what to do for them identifier.
The battery of your Seat Mii is discharged
This remains without any uncertainty the most usual dysfunction, and probably the easiest to troubleshoot. The headlights of your Seat Mii will be left on for hours, the pilot light inside the vehicle, or simply the ignition on, or the like. Everything that can consume electricity while engine block remaining off could be the root of the problem. However, this also happens if the battery turns out to be far too old, or even alternator. To check if the battery of your Seat Mii is empty there is a frankly affordable way. If the headlight lighting is low, it means it's a battery malfunction! On the other hand, in the case where the headlights work correctly, it means that the dysfunction comes from elsewhere. To fill the battery, you probably know how to fill it, and you should always remember to have cable inside your trunk. It is also conceivable that the thimbles of the battery be oxidized. Then it is only necessary to open your hood and check if they are blocked. Then you will be able to remove the dirt thanks to a stroller. In case it doesn't work, you will need to replace the battery.
Seat Mii starter is worn out
It happens less often than an empty battery but it could still happen at times. To know what to do it will be necessary to understand what a starter is for your Seat Mii. There is a kind of engine within the engine. What sets it apart is that it is completely electric. Indeed, it is this which will start the engine, and the electricity required for its operation comes from the battery. To make it work you just need to hit a few times small strokes on its surface so as to take off the coals to leave electricity circulate.
The engine of your Seat Mii is flooded
Hopefully this is not the case. Sometimes it is still possible to start your Seat Mii, but it also happens that the engine becomes irreparably broken. This is something that happens especially when it is cold. In general, you will be able to discern it when you try to start the engine and you feel a strong gasoline smell. Sometimes it will be enough to wait half an hour and the malfunction will be resolved. For petrol cars it is also possible to dry petrol in the spark plugs but it is a manipulation not recommended for novice DIY enthusiasts.
Conclusion
If your Seat Mii does not start, it can come from a electric problem and less frequently of a engine problem. You now know the main solutions to be able to distinguish the dysfunction, even if all this really does not want to leave, we invite you to go to a professional, they are paid for it after all!
