One of the best luxury cars ever built is the Mercedes-Benz 300SEL. With its powerful engine and unique design, this vehicle has inspired many car owners and automobile manufacturers around the world. Unfortunately, despite its success, this vehicle still encounters problems that can affect its overall performance. Listed below are some of the issues that car owners may experience with the 300SEL.
One problem that plagues many Mercedes-Benz 300SEL owners is intermittent power loss. Although Mercedes-Benz has not issued any recalls regarding this problem, some car experts suggest inspection of the intake valves to diagnose the problem. However, if the valves are not the culprits, then the fuel injector should be checked for leaks.
In case that these are not the reasons why the 300SEL is experiencing power loss, then fuel volume and pressure should be examined carefully. If the pressure is rated below 76 and 79 psi and volume is measured at less than one liter every 40 seconds, then these may be the roots of the problem.
Although this is not a serious problem, some 300SEL owners still complain about the varying rim offset of this vehicle line. For those models equipped with 6.5-inch rims, their rim offset is measured at 21.5 mm. On the other hand, for those with 7-inch wide rims, then their offset is 25 mm. Car enthusiasts and experts recommend proper measurement of the offset to avoid ill-fitting tires.
According to an online car care website, one of the most common problems encountered by many car owners with the Mercedes-Benz 300SEL is having failed window regulators. Most especially with the 1990 and 1991 models, this problem causes the door windows to get stuck whenever they are raised or lowered. To solve this problem, replacement of the faulty window regulators is necessary to avoid recurring issues.
Another problem that 300SEL owners should take note of happens when the weather is too cold. Although cold starting is a fairly normal thing to do, some 300SELs, particularly those manufactured in the 1987 model year, have issues with this. To solve this problem, the fuel system accumulator and cold start injector should be inspected for damages. However, repairing or replacing these parts without guidance is a no-go because they tend to be expensive and making a wrong diagnosis will only lead to more complications.
