About Mercedes-Benz 420SEL

As a model in the Mercedes-Benz W126 lineup, which is a series of S-Class automobiles and the S-Class is formerly known as Sonderklasse (German for "special class", abbreviated as "S-Klasse"), and is Mercedes-Benz's flagship as well as the successor to Mercedes-Benz Type 300, Mercedes-Benz 420SEL was built by the Daimler-Benz between 1986 and 1991 as a full-size luxury car. Originally introduced as a model of the second-generation S-Class, 420SEL was available for only six model years before being discontinued.
Mercedes-Benz 420SEL (W126) made its debut for the 1986 model year when the S-Class was in its second generation. It was offered in only one body style, 4-door sedan and came in only one trim level. "SEL" in its name S-Klass-Einspritzmotor-Long wheelbase in German. Just like other models in this lineup, 420SEL also introduced many Mercedes-Benz safety innovations, including the first seatbelt pretensioners. Besides, it was also equipped with driver side airbag, passenger side airbag, Traction Control System (TCS), namely Acceleration Slip Regulation (ASR), Anti-locking Braking System (ABS), crumple zones front and rear, fluted taillights, high strength low alloy steel, courtesy lights on the underside of the doors, eight-way powered, dual stage heated front seats, and optional automatic climate control and others.

Mercedes-Benz 420SEL Common Problems & Maintenance Tips

The W126 was praised for its improved ride, better handling and improved fuel efficiency and Mercedes-Benz 420SEL helped retain the S-Class market leadership as the world's best-selling prestige luxury sedan. But as an at least sixteen-year-old vehicle, you had better learn about these common problems on your 420SEL:
First, a rough running engine is what Mercedes-Benz 420SEL drivers complain most during their driving. This is obviously an engine problem and it could bring devastating consequences if dealt with improperly. In fact, not many 420SEL drivers know how to diagnose and solve it in time and that is why these symptoms will be a lot of help for you. If the engine starts to make strange sounds including whining, squealing or rattling when in operation; if the engine misfires, stalls and even suffers from starting issues such as hard starting or inability to start; if the vehicle loses power when acceleration and has poor gas mileage; or if the Check Engine Light is activated, then these signs are the best indicators that the 420SEL spark plug, air filter, oil filter, engine control module, oxygen sensor, exhaust manifold gasket, fuel pump and valve cover gasket are out of the order.
Second, another common and tricky problem on Mercedes-Benz 420SEL is the transmission failure, which is often misunderstood or underestimated. It could not only bring drivability issue and even make the vehicle lose the ability to move. According to professional 420SEL repairmen, when there are clunking or grinding noises coming from underneath the vehicle, you should keep alert. Next, you will find leaking transmission fluids, the indicator not matching the gear, the vehicle starting in another gear or refusing to go into any gear, transmission slippage and surging, as well as you find difficulty in shifting gears. All these symptoms could be attributed to the 420SEL transmission assembly, shift cable, automatic transmission filter, automatic transmission shifter, transfer case seal and clutch fork.
Moreover, please value the role of routine maintenance on vulnerable auto parts of your Mercedes-Benz 420SEL as some parts just could not last as long as the vehicle could due to fragile materials and harsh working conditions. Not to mention the 420SEL seat belt, windshield wiper, wiper blade, antenna, cabin air filter, fog light and headlight also undertake the responsibility of creating a safe and comfortable driving environment. You should maintain them routinely to ensure a safe and comfortable driving experience.
