Why does the Mercedes-Benz car keep making noise?
2 Answers
Mercedes-Benz car noise reasons are as follows: Engine mount rubber aging or loosening: The engine mount rubber is the rubber block between the engine and the frame, mainly used to reduce vibration and cushioning during engine operation, and it also has the effect of fixing the engine. If the engine mount rubber ages or loosens, it will cause the engine to shake, and in severe cases, a "clicking" noise will occur. In this case, the engine mount rubber needs to be replaced. Engine mixture too rich: This causes the Mercedes-Benz car to have difficulty accelerating after starting, uneven engine operation, black smoke from the exhaust pipe, accompanied by a clicking noise from the engine, reduced engine power, and increased fuel consumption. In this case, it may be due to carbon deposits in the engine or a clogged filter, and generally, a major overhaul is not required.
It's quite common for Mercedes-Benz cars to keep beeping, usually it's the alarm system reminding you. Maybe a door isn't closed properly—check all four doors and the trunk to see if something's stuck; it could also be the seatbelt reminder that won't stop, especially if there's something heavy on the passenger seat making the car think someone's sitting there. Key fob issues are particularly annoying—when the battery is dying, the car will beep nonstop. Worn-out brake pads can produce a metallic scraping sound at their limit, which feels as unpleasant as nails on a chalkboard. If the dashboard suddenly lights up with a red warning light accompanied by a buzzing sound while driving, pull over immediately—it might indicate an emergency with the engine cooling or braking system. Don't ignore these situations; contacting a 4S店 technician directly is much better than trying to fix it yourself.
