Common Issues with Mercedes Benz ML350 Headlights
Your Mercedes Benz ML350 is a tried and tested vehicle that's known for superb performance and smooth handling. But as some owners have noted, there are certain problems with its stock headlights. Some folks have reported that the beams are too weak at times, which can be a problem when you're driving at night or in heavy rain. Headlights, like all car parts, are susceptible to wear and tear so you'll need to replace them as soon as they wear out. Take note of some of the common problems with this vehicle's headlights so you can have them fixed right away.
One of the headlights isn't working
If one of your vehicle's headlights isn't working, then you have to rule out if the bulb is already burned out or if you simply have an electrical connection to deal with. Inspect the wires and connectors on the back of the headlight to see if anything is corroded or loose. You'd also want to use a multimeter to check if there are any other problems with the wires. If all the connections are good, then you'd need to inspect the headlight's bulb to see if it's burnt. Burnt bulbs should be replaced immediately. Most headlight bulbs last around five to six years of normal use, so if you're nearing that number, then you'd want to check on your headlights occasionally as they'll probably need to be replaced sometime soon.
Most owners have reported that some Mercedes Benz ML350 Headlights appear to be quite dim. Although Mercedes hasn't issued a technical bulletin addressin this issue, a couple of possibilities can affect the brightness or dimness of the headlights. First, a bad alternator or a slipping drive belt could be affecting the power or current that's flowing into the headlights. Underpowered headlights will not operate at max brightness and could even get damaged over time. Check the alternator and drive belt and see if this solves the problem. On the other hand, dirty headlights, fogged up headlight covers, or even moisture inside the covers can affect the brightness as well. Simply cleaning it inside and out should solve the problem.
