2012 Mitsubishi 2.4 DI double cab diesel – fuel filter warning light came on and I remover the draining screw and drained the filt

ANSWER : Hi there. A warning indicator light is triggered when a sensor notices a fault and creates an error code; which is stored in the ECU of a vehicle until the issue is resolved. In most cases, the error code needs to be cleared from the ECU in order for the light to be removed. I would recommend having a professional mobile mechanic come to your location and complete a warning light inspection, so they can clear the codes and verify that the issue has been resolved. While they are there, if the light still remains, they can identify what steps are needed to fix this issue.

ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

ANSWER : You are using the correct filter. I looked at the photos that you sent but the photos do not show the entirety of the threads. Even if such are shown "clearly", when it comes to threaded parts, it only takes a fairly minor defect in threads to make assembly difficult. If you cannot visually detect any gross amount of damage to the threads, the thing to do is manipulate the oil filter as you attempt to thread it on. That usually works. Given your description, in your case, it would appear that there is some very minor defect, perhaps a metal splinter or the like, that is preventing the engagement of the first thread in the filter. That is not exceptional (it happens) and thus to get it to engage you will just have to inspect and try again. Don’t force it though. With reasonable measures, if you truly cannot get the filter to engage, the external threads will have to be restored. If you have enough access, you can gently use a thread file or use the appropriate die. If you want these steps performed by a certified Mechanic, dispatched by YourMechanic right to your location, please request an oil filter base repair/installation and the responding certified mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

ANSWER : Hello, thank you for writing in. Your head is in the right place. While gas these days is held to some better standards, its very possible to collect debris in the tank over time. Considering the mileage on the vehicle, replacing the fuel filter is a great idea anyway, and you should definitely do so. They are quick and easy to do, but you need to be careful with the fuel lines. Also make sure you install the filter in the correct direction. If your fuel pump is original, then you may want to consider replacing it as well. Running a vehicle to empty can hurt the pump. It is also a great time to inspect the tank for debris. For more help replacing either fuel component, contact our service department to schedule an appointment.

ANSWER : The switch you are referring to is vended with the required electrical and fuel schematic (I just looked in the box) that answers your installation question. If you want an advance view, here is a link as well. Yes, you need a return line and just refer to the aforementioned link. If you are retrofitting back to OEM, I strongly encourage you to buy the original Factory Service Manual (FSM). There are lots of details attending this system and obviously it is difficult to recount it all here. The FSM will make your life much easier and you can then make sure your installation is perfect. Alternatively, YourMechanic can dispatch a certified mechanic and perform the whole retrofit and check out if you desire. Just request and schedule a generic service such as fuel pump service and the mechanic will come to your location and estimate the parts and labor required. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

ANSWER : Hello- the warning light you mention is a " low coolant" indicator. Once the engine is cool – check your coolant reservoir and/or cooling system for proper fluid level. Since you seem to have lost fluid, I would recommend an inspection of the cooling system by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

ANSWER : Hello. From what you describe, it would appear that your vehicle is having some sort of electrical issues. The "Generator Inverter Performance" warning comes on when the computer detects an issue with the vehicle’s electrical generator inverter. The generator inverter is the component that converts the high current electricity from the vehicle’s hybrid battery into a lower power form of electricity that is useable by the vehicle’s various systems.

The inverter is located in the engine bay, as the silver box on top of the engine. Unfortunately, the inverter is a critical component to the functionality of the hybrid system, and therefore to the operation of the vehicle, and, as a result, needs to be repaired or replaced before the vehicle will run again.

The VSC system warning light comes on when the computer detects an issue with the vehicle’s stability control system. This is usually due to a fault with the wheel speed sensors or the ABS module, though electrical issues can sometimes effect this system as well and cause it to behave erratically. I would start by taking care of the generator inverter issue and going from there.

I recommend having a certified mechanic, such as one from YourMechanic, perform an inspection to determine why the warning lights are on and suggest any needed repairs.
