Mercedes-Benz 350SD Problems
| Brakes |
- Due to the size and materials of the brakes on these vehicles, the brakes start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
- Brake fluid should be flushed every two years to prevent premature anti-lock brake system (ABS) failure.
|
| Engine |
- Oil leaks can develop around the oil filter housing.
- Fuel leaks can develop around the high pressure fuel injection pump.
|
| Suspension & Steering |
- The tie rod ends, drag link, and idler arm in the linkage of the steering system can wear out.
- There is a steering dampening shock that will leak fluid when it goes bad.
- Power steering hoses and components can develop leaks.
- On high mileage vehicles, rear spring wear may cause the rear end to sag.
|
| Drive Train |
- A vibration felt through the center floor
of
the vehicle can be caused by driveshaft flex discs, which crack and
shred, causing excessive driveshaft movement. Not repairing these can
cause damage to the driveshaft center support bearing, or, in the worst
case
scenario, damage to the transmission or differential.
- High mileage vehicles can leak from the transmission oil seals.
- High mileage or older vehicles develop leaks
at the differential seals and cover; the whole unit needs to be
resealed to repair the leaks.
- 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.
|
| Electrical & Lights |
- The fuel pump and fuel pump relay can fail, causing the car to crank (when starting), but not start.
- The instrument cluster, along with the turn signal and wiper combination switch, can fail.
|
| Heating & Air Conditioning |
- Other than a defective motor, a bad switch or blower motor resistor assembly can cause inoperative heater blower motors.
- The climate control system can fail or perform erratically due to internal wear in the climate control unit buttons.
- The AC coolant hoses may leak.
- The expansion valve can get stuck and is difficult to replace.
- Due to the vacuum actuators going bad, temperature blend doors in the HVAC system may stop working.
