The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

1992 Mercedes-Benz 300SD 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.
Problems with the pneumatic system can cause closing assist and door lock issues.
The tie rod ends, idler arm, and/or drag link components of the steering linkage may wear prematurely. Please keep in mind the wheel alignment should be checked and adjusted when any of these items are replaced.
As brake fluid becomes dirty over time, it can cause a failure of the anti-lock brake system (ABS) modulator assembly. Our technicians recommend a complete brake system flush every two years to help prevent this issue.

1992 Mercedes-Benz 300SD Reviews
Beautiful road car. Well balanced. With me, a full tank of fuel and a suitcase in the trunk the car has 2500 lbs on the front axel and 2500 lbs on the real axel. Has long legs (28 gal tank and 30 MPG on the road) which gives me an 840 mile range to fuel exhaustion.
I had just about everything replaced under MB warranty (new factory crated engine, turbocharger, A/C evaporator, water pump, valve guides, front springs, shocks, control arm bushings, engine boost sensor, manifold pressure sensor, crankshaft position sensor, engine mounts, Glow plug harness, Engine Harness, and a few other things). The car is a dream to drive. I have spent 33 hours at one time and felt great. Just roll the seat back for a nap and wake up and start driving again.
If you are considering this car make sure you have a new, or remanufactured engine as the original engine had rod problems. Look for one where the owner has ALL the paperwork (preferably from an MB dealer) on all work and has a complete set of maintenance records. It’s not a car for the back yard mechanic and plan on spending a few bucks on routine maintenance, but if you want a car that you can ride in all day and arrive in comfort. This is the one to own. The car is equipped with thermo pane windows which keep the noise and cold out. Car is very quiet, most don’t even know it’s a diesel. Very responsive (for a diesel) and handles like a sports car.
This car is still in style even after 20 years. This was the Princess “Di” car and had she been wearing her seat belt she would still be alive.
I rated the engine and A/C down for the original equipment. Once replaced I would give it a 5 star.
