My car has only 28,392 miles on it, but the yellow check engine light recently came on due to a faulty oil pump solenoid. I took it back to the dealership, and the repair cost was a staggering $7,000; they told me this is a common issue with this Mercedes engine. If this fails to function, engine noise will increase while driving and fuel consumption will rise; there may also be other unknown risks. The issue stems from a manufacturing defect that causes the malfunction indicator light to remain illuminated, preventing the vehicle from passing the annual emissions inspection and rendering it ineligible for legal road use; furthermore, the repair entails removing the front subframe and oil pan, resulting in unreasonably high repair costs.
