Mercedes-Benz The S-class
Model 190, with love named "kid-bentsem", was made with 1982 for 1993, but also now it not seems old. It became the answer to release by concern BMW in 1982 of completely processed 3rd series. Both cars – representatives of middle class and direct competitors. The new class C which has come in the stead to a series 201 in 1993, still in большей to a measure personifies quality of production Mercedes.
As to cars of a new class With, 190th models which have come in the stead these cars in many respects differ from predecessors to the best. Their bodies serve without any problems till present time. The full serial equipment (adjustable seats, АБС, the air cushion of safety for the driver) provides pleasant driving and safety. But also in these cars there is a number of lacks. So, in some cars of release of 1994 there is an aerodynamic noise because of bad adjustment of locks of forward doors, and in cars of release till May, 1995 – a fragile hook-clamp of a cowl. In January, 1996 of 545.000 cars it has been withdrawn for defect elimination.
Fabric covering, as well as in cars of the previous generation, gloomy. It is behind poorly place for passengers, forward seats in some cars of release of 1994 (it, the truth, is easily eliminated by simple greasing of corresponding elements) creak. Only in few cars (approximately 3 percent) release of the same 1994 depart a covering of internal handles of doors. Besides, the scratch and a gnash are heard at lifting of glasses of forward doors in cars 1994-1996, in particular, in a hot season (it is eliminated in December, 1995 by replacement of a directing sled and greasing).
Assemblage of salon of cars of the S-class is executed carefully, only separate ordinary-looking plastic details spoil impression a little. In cars of all years of release a sled of the hatch of a roof is badly adjusted, occurrence of scratches in an operating time of a drive of the hatch is possible. Besides, in all cars there can be a noise at work заслонок systems of ventilation of salon, and also deformation (swelling) of the top part of plastic at the basis of forward lateral glasses after 1–2 years of operation. Last phenomenon is especially characteristic for cars of release of 1993.
In cars 1994-1995 it is established трудноотпускаемый (especially in a cold season) the lever of a lay brake. It occurs because of too thick layer of a corrosion-resistant coating in the bottom part of a body that causes bad moving of a cable of a drive of the lever. In the spring of 1995 cars have been withdrawn in a place of sale for lack elimination. In general, shock-absorbers, disks of brakes and especially coupling show durability much above an average level. At purchase it is necessary to mean that the hydraulic booster should be serviceable, differently its replacement will manage in a round sum. A steering wheel too big in cars of all years of release.
Have lacks and engines of cars of a class of S.Tak, in version С220 of release of 1994 the raised turns of idling (they spontaneously increase to 2000 turns in a minute) because of defect in a drive throttle заслонок are noted. This lack can be eliminated by change of a fixing pad of a cable. In version С230 with турбокомпрессором there are separate cases of refusals of the compressor because of easing of fastening of an air pipe on an exit of the air filter (it is eliminated since November, 1995).
All cars of a class With are characterised by bad dispersal at not heated-up engine, therefore until the motor will not get warm to working temperature, the accelerator pedal is necessary for pressing cautiously, carefully dosing out gas mixture giving. In versions С200D/С220D of release of 1994 there are failures in engine work, in particular, during acceleration at average turns (because of problems in the computer (a chain of management ТНВД)). On separate cars the engine management computer was replaced on a guarantee. In versions 220D/250D release of 1994 take place noise of valves and нагарообразование on the final valves, causing loss of capacity because of compression decrease in cylinders (valves are not closed completely). The problem is eliminated in 1995 by drawing of a chromic covering on cores of valves.
The electric equipment very good and censures does not cause. The only thing that it is possible to note here, changes of adjustment of external rear-view mirrors at closing of doors in cars 1994 (class). In the cars equipped with the conditioner of air, after its deenergizing glasses, especially in case of strong pollution of the filter immediately mist over.
What to prefer?
Car Mercedes with 201st body is standing purchase. And it even still in a greater degree concerns cars of a new series With.
In version С230 with a turbo-supercharging: possibility of refusals турбокомпрессора because of easing of fastening of an air pipe on an exit of the air filter.
In all cars of a class With: bad dispersal at not heated-up engine.
In versions С200D/С220D of 1994: failures in work, in particular, during acceleration at average turns of the engine (because of problems in a chain of management ТНВД).
In versions С220D/С250D of 1994: noise of valves, deposit formation on final valves.
In cars 1994-1995: трудноотпускаемый (especially in a cold season) the lever of a lay brake.
Progressing deformation of a plastic framework of external rear-view mirrors.
Pochernenie coverings of the sun-protection peak, amplifying eventually (especially in cars with the hatch in a roof), deformation of a plastic frame of a ware box after 6 years of operation.
In some cars of release of 1994: aerodynamic noise because of bad adjustment of locks of forward doors.
In cars of release till May, 1995: fragility of a hook-clamp of a cowl.
In cars 1994-1996: a scratch and a gnash at lifting of glasses of forward doors.
