Mercedes-Benz C220 oil light warning with correct oil level and no leaks detected on Mercedes-Benz C220

Some Mercedes-Benz C220 owners report experiencing oil light warnings despite having the correct oil level and no visible leaks. These warnings may be triggered by a malfunctioning oil pressure sensor that provides incorrect readings to the vehicle's system. Additionally, a clogged oil filter can restrict oil flow, resulting in a drop in oil pressure and activating the warning light. Some owners also report issues with a failing oil pump that fails to circulate oil effectively, leading to low oil pressure. Inaccurate readings from the oil level sensor can further contribute to the problem, causing the warning light to activate even when the oil level is correct. Furthermore, the expansion of oil with heat in warm conditions may falsely trigger the warning light, necessitating the removal of excess oil to resolve the issue. It is recommended that owners experiencing this problem have their vehicle inspected by a qualified mechanic to diagnose and address the underlying causes promptly, ensuring the proper functioning of the oil system and preventing potential damage.
