Reset Vito Service Light

[Cassaundra Marley]

Ifthere is a Mercedes-Benz check engine light flashing on your car's dashboard or center console, get in touch with our dealership for a Mercedes-Benz check engine light diagnosis and reset. There are many causes for a check engine light to come on.

A check engine light can come on to alert you to something as benign as a fuel cap that isn't securely fastened or something as serious as an issue with your car's engine. That's why it's essential to schedule a Mercedes-Benz check engine light diagnosis with our certified service center right away.

There are several reasons why the Mercedes-Benz check engine light has turned on. The most common include a malfunction with the fuel injection system, a damaged oxygen sensor, faulty head gasket, dirty mass airflow sensor, defective spark plugs, or a faulty emissions control part.

When you bring your vehicle in for service, our technicians will diagnose why the check engine light has turned on in your vehicle, fix the problem, then reset the check engine light. There are two ways to reset the check engine warning light on vehicles from our new Mercedes-Benz inventory.

The quickest way to diagnose and reset a check engine light is with an OBDII Scanner that reads the diagnostic codes for your vehicle. One of our technicians will plug a compatible scanner into your vehicle, and the car's computer will give the scanner a code for what seems to be the trouble.

If you want to get a sense of what's turning the Mercedes-Benz check engine light on and off in your vehicle, there are plenty of code readers and scan tools you can purchase in your local auto parts store or online. If you're looking for a recommendation for the best OBDII scanner you can buy, feel free to speak with the associates in our service department.

Some of our customers like to work on their cars themselves. If you like to turn a wrench and need to perform a Mercedes-Benz check engine light reset without a scanner, the first thing to do is remove the fuel filler cap then screw it back down securely. A loose fuel cap is one of the most common causes for a check engine light.

Next, disconnect the negative battery cable and wait a few minutes. The positive terminal will have a + symbol embossed into the plastic, often covered by a RED plastic cap. The negative terminal will have a - symbol and may have a black cap over the terminal. When working on your car's battery, be sure to wear the necessary safety gloves and glasses.

A simple socket set will likely be all you need to loosen the nut on the battery terminal cable and wiggle off the cable. Disconnecting the negative battery cable for 30-60 seconds should clear the check engine codes and reset the diagnostic system.

If you set the negative battery cable to the side, make sure the cable does not touch the battery or any metal parts of the vehicle to avoid grounding the circuit. If the problem was indeed a loose fuel cap, the light should turn off immediately.

If this does not work, the next thing to do is repeat what you just did, but before you reinstall the negative battery cable, press the car's horn or turn on the headlights. This will release any stored energy in your vehicle's electrical circuit and cut all power to the check engine light.

If the light is still on after trying this, it now becomes a matter of trial and error with attempting to check the spark plugs, fuses, O2 sensors, etc., and disconnecting/reconnecting the negative battery cable after each attempt.

There are several possible reasons why the check engine light has turned on in your vehicle. If the check engine light ever illuminates your car's dashboard, we suggest bringing your vehicle in for certified auto repair at our Mercedes-Benz dealership right away. A check engine light can indicate a problem with the fuel injection system, the fuel system, the exhaust system, the engine management system, or the ignition system.

A check engine light will only reset itself automatically once the problem that caused it to turn on is resolved. When you bring your vehicle to our service department for a check engine light repair, our technicians will use a scanner to diagnose why the check engine light is on. We will then repair the underlying issue and reset the check engine light.

In most cases, yes, you can drive your Mercedes-Benz with check engine light on, but we recommend bringing your car in for check engine light repair immediately. A problem with the fuel system can cause your vehicle to enter emergency mode or "limp home mode," which turns off many vehicle systems and limits the vehicle's speed. If a faulty O2 sensor has tripped the check engine light, driving your car can damage the catalytic converter, which can be an expensive repair.

The yellow engine light is most likely a check engine light. There are many causes for a check engine light to come on, including a problem with the fuel system, the exhaust system, the fuel injection system, the ignition system, or the engine management system. A check engine light will not reset itself and should not be ignored. Check engine light codes range from minor to severe and should be immediately diagnosed by certified Mercedes-Benz technicians.

the check engine light came on a little bit ago and we got it tested and it was the mass air flow sensor, we recently about 2 weeks ago changed it but the engine light remains on and i know its supposed to take a minute to go out but its been longer now, also every time i get gas (it did this before i changed the MAF as well and was a result of needing to change it) and i turn the car back on the entire car shudders and goes quiet like its stalling out or something, it usually takes a few seconds to get back to normal or else I have to just turn the car off and turn it back on again and its fine, but it is still doing this after its been 2 weeks and the gas gauge now seems to be slowly fluctuating like earlier it was at the last tick mark and then after about 10 minutes it was suddenly at the middle but then it evened out again but still

When you change a MAF sensor, you need to disconnect the battery for about 10 minutes so the computer forgets the learned parameters and resets to the factory parameters. Then it goes into learn mode and may take a little while before it learns all the parameters of the new MAF sensor.

Both of these statements make me think that you have at least one poor connection at one of the battery cables. Either at the battery , or at the other end of the cable. Be sure you take the terminals off and clean the terminals and battery posts. Just brushing off the outside is not enough.

You may have more than one problem. The poor engine performance after filling up w/gas makes me think you have a problem in the evap system. When you fill up w/gas the fumes in the gas tank are supposed to be pushed into the evap canister. Then when you start the engine after a fill up the evap canister is supposed to hold onto those fumes until you get up to a certain speed or engine load, at which point the evap canister (the purge valve) is supposed to open up and meter those stored fumes into the engine to be burned. If the fumes are allowed directly into the engine when the car is first started (after a fill-up) or at idle it will run too rich to compensate for, and cause this sort of symptom. The fuel gauge symptom could be related to an evap problem too. Generally that would throw a code for fuel tank evap pressure or something like that.

I would respectfully disagree with mandating code clearing for the following reasons. 1: when contitions are met the computer will turn the check engine light automatically. Sometimes the ECU does not instantly check the repaired system and light May stay on for the first few times of driving. 2: If you clear the codes and do not remedy the problem yourself, you may taking your car to a mechanic, and you may have (probably have) made his job much more difficult if all codes have been cleared. Almost always the ECM does a very good job at clearing itself and maintaining memory of past behavior.

I have changed my mass air flow sensor twice with OEM parts, reset the code multiple times, put a new K&N air filter in and the light still comes with in 3 or so miles. I have a 2017 Titan XD with the Cummins. I did find a skinned wire that looks like a rodent got it but I soldered it back together so it is solid.
