Since 2006, German auto manufacturer Mercedes-Benz has produced its CL Class line of luxury vehicles, with some of the best technological advances standard on every car. Several monitoring systems function to keep the vehicle running clean and efficient. However, some Mercedes owners experience problems with the emissions system on their automobiles.
Most frequently, Mercedes owners that have issues with the emission system, describe a situation which presents itself as a check engine light that will not shut off. Others might not find they have an issue with emissions until their car must be registered and fails an emissions test. Less frequently, some Mercedes drivers report they hear an extremely faint hissing noise immediately after starting their vehicle.
A failed emissions test is best left to an expert to diagnose the cause of the issue. This may be symptomatic of a secondary air pump that has gone out in your Mercedes-Benz. Hissing noises may be associated with leaks in the same secondary air pump. Or cracks in the hoses that are part of the car’s ventilation system may be the source of the leak. While neither of these issues will keep you from driving your car at first, it will definitely affects your vehicle’s performance.
Any chance in your vehicle’s operations should be examined at your local Mercedes-Benz repair garage. They can easily evaluate your vehicle’s performance and recommend repairs. Their knowledge and commitment to safety enable them to impart a regular maintenance schedule to follow that will ensure the long life of your eco-friendly vehicle.
