Mercedes-Benz E420 Problems
Due to wear, high usage vehicles can experience ignition lock and tumbler failures. The ignition lock cylinder will generally require replacement to correct this concern.
Oil feed tubes break and fall into the crankcase (engine) and the tappet becomes noisy (ticking), resulting in degraded idle quality. Our technicians recommend replacing all of the tubes at the same time, broken or not.
A coolant leak may develop form the Radiator due to degradation of its plastic components. Replacement of the failed radiator will be necessary.

Mercedes-Benz E420 Reviews
1997 E420 Sport - My first Mercedes, bought from a friend's estate. Car is a creampuff, 95,000 miles and all dealer serviced. The exhaust system is like a new car, not rusted, the chassis is really olid,again no rot. The materials used are very high quality and the car holds up well as a result. Over the years and during the extended warranty the tranny was replaced, as was the AC blower motor...
The ASR light came out and the ABS light same time came on and all gauges stopped working. When engine was shut off, it could not be started and all the lights came on.
Great car but has a poor Electrical Wiring System
