Owning a car means that you will always be prone to having car problems. They will come in different sizes and shapes these problems. When you do have problems it doesn’t mean that you should always head to a garage or a mechanic. There a lot of repairs that can be done on your own. Most of the repairs that cars need regularly are very basic repairs. Knowing when you need to head to a mechanic or a garage is a skill. The more you try to repair it on your own the more you will know when to take it to the garage. Here are some basic repairs.
You start thinking about repair when your check engine light lights up. This can happen sometimes even when there are no repairs so try to just remove the gas cap and re-close it tight. There are chances when it is not closed properly a code in the car will cause the check engine light to appear.
If the light is still try to reset your ECM or PCM. You can do this buy remove the negative battery terminal for a few minutes and then putting it back on. This will reset the ECM or PCM. If the lights still comes up then it is some other problem.
The ECU also called as the Engine Control unit is a system that monitors all the data recorded by the different types of sensors in the engine and they also make necessary changes to the engines depending on these changes so that the car’s engine runs in an optimal level. When a car modification is done it might conflict with this system. Instead of waiting for the ECU to adjust itself you can manually reset it. Instead of taking it for BMW service be your own BMW mechanic and fix it. Of course if you really think you’re going to mess it up might as well take it to proper mechanic but learn from him when you take it to the mechanic.
You reset the ECU by removing the fuses out for a few minutes as well. Pop the hood and you will find the fuse box most probably on the passenger side of the battery. Remove the lids and remove the fuses. Some fuses are located in different locations so check out your manual from the company or the person you bought it from. (Highly doubt you got it from the person you bought the vehicle from so google it).
That’s basically to checking the car engine. Hope everything works out well.
