Mercedes-Benz 190E Problems
RepairPal has identified the most common problems with the Mercedes-Benz 190E based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The AC system may not blow cold air due to Refrigerant leaks from AC manifold hoses. Leak diagnoses, most commonly using leak detection dye, may be necessary to determine the exact location of any leaks.
The cooling system hoses may fail unexpectedly. The hoses can look good on the outside, but the rubber can degrade and erode on the inside. If not carefully checked, the hoses can burst at any time.
Motor mounts commonly fail, causing engine vibrations to be transferred to the body. Failed motor mounts should be replaced in order to prevent damage to the transmission mount.
Due to age and sun exposure, the interior wood trim cracks and the finish gets a cloudy haze. Replacement if the trim would be the most common solution to the problem.
The sunroof may not work correctly due to failed components as a result of age and wear. Repairing a sunroof can be labor intensive and very costly.
High mileage vehicles may develop a transmission fluid leak from one or more of the oil seals.
The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.
The bushings for the shifter lever wear out to the point where they break and fall out. This causes excessive movement (loose feel) in the shifter lever and a clanging-type noise when changing gears.
Fuel leaks, erratic or rough engine operation, and fuel economy issues can be caused by the failure of a fuel system component called the EHA (electro-hydraulic actuator) valve.
