1998 Mercedes-Benz E320 Problems

Malfunctioning Regulators May Cause Blower Motor Failure

A malfunctioning HVAC blower motor regulator 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.

Failed Exhaust Catalytic Converter May Cause Rattle From Beneath Vehicle

When the engine is running, but the vehicle is not moving, a rattle heard from beneath the vehicle could indicate that one of the exhaust catalytic converters has failed. The substrate (the internal part of the catalyst that reduces emissions) can loosen and bounce around inside the canister section of the converter—the defective unit will need to be replaced. If this problem is ignored, the substrate can break down and reduce to a size that plugs the outlet pipe, which will cause a sudden loss in power.

Changed the oil every 7,000 mi (synthetic). Changed the brake pads once (routine maintenance). No expenditures at all. Still looks new. Will eventually put money into it and restore it completely (perhaps in a couple of years or so). ...
I have owned this car since 2000 and I am very happy with the experience. I purchased it as a two year old lease return. I have garaged it since purchase and maintained it annually. I also have it detailed after each winter inside and out. Feeding the leather annually has kept the leather supple and like new. I live in a non-snow/road salt area so there's no rust.
