I own a 2000 430, and other than replacing a hose for the airconditioning, It has been a joy to own and drive. It now has 98,000 miles and drives like a new car. I am the second owner, the first, according to my mechanic took very good care of the car, which is why it looks and drives beautifully.

Great car; however, excessive repairs are needed, which is really costly.

Mercedes-Benz E430 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 from the PCV vent housings on the valve covers and inspection plates on the front of the engine are common.
  • The rubber bond in the harmonic balancer can decay, which causes the balancer to move and work its way into the timing chain cover. If the balancer comes into contact with the timing cover while the engine is running, it will fracture and damage the timing case and potentially other surrounding parts. The harmonic balancer should be inspected at every service.
  • Oil leaks from the oil level sensor are common.
  • The crankshaft position sensors tend to fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance. Communicating these specific symptoms to your technician can save diagnostic time.
Exhaust & Emissions
Suspension & Steering
  • Irregular and premature tire wear can be caused by the lower control arm bushings cracking and causing excessive movement at the control arm pivot point. Ball joints can also wear out prematurely, causing similar tire wear symptoms.
  • A squeak from the steering column is often related to a rubber boot in the column or a seal in the power steering rack.
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
  • Tail lamp housings can melt, resulting in a loss of contact for the brake light bulb holder. If this happens, the brake lights will not work. 
  • The third (high) brake light housings melt, resulting in a loss of electrical contact for the light, which stops working. A complete housing (contacts and lens) is needed to repair the problem. On certain vehicles, if this happens, the anti-lock brake system will not function. The brakes will work in normal mode, but not provide the ABS control.
  • Instrument cluster displays tend to fail, especially the clock and gear indicators; the instrument cluster needs to be replaced.
  • Brake light switch failure can cause the ESP and BAS warnings to illuminate.
  • PSE system, voice control module, or Tele Aid module failure can cause a lack of audio. These same modules can also cause dead battery conditions when they fail to "time out." Many electronic control modules are active even when the engine is off. If these modules stay active, they will drain the battery, which is why they have a timer built into the modules. The timer shuts down the modules after a preset amount of time (timing out). If a module does not time out, it will stay active and drain the battery.
Heating & Air Conditioning
  • Malfunctioning blower motor regulators can cause the blower motor to operate below the requested speed or not at all. Updated regulators are available; the blower motor and cover need to be replaced at the same time  to upgrade the system.
  • The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not cycle on, the AC system will not blow cold air. If the AC compressor is stuck on, the air will be very cold at first, before warming up.
