Common Issues in the 1998 320E and How to Fix Them
Before diving into specific fixes, it’s helpful to understand the common culprits behind a 1998 320E’s woes.
Engine Problems
1. Rough Idle:
- Possible Causes: Vacuum leaks, faulty spark plugs, clogged fuel injectors, or a failing idle air control valve are frequent offenders.
- Troubleshooting: A diagnostic tool can pinpoint the issue. “The ability to quickly and accurately diagnose engine problems can save you time and money,” says automotive expert, Michael Carter, author of “Modern Automotive Diagnostics.”
- Solutions: Replacing worn-out components or cleaning clogged parts usually resolves rough idle.
2. Overheating:
- Possible Causes: A malfunctioning thermostat, low coolant level, or a failing water pump are common culprits.
- Troubleshooting: Check coolant levels and inspect for leaks. If the coolant is low, there’s a leak somewhere in the system.
- Solutions: Replacing the faulty component, such as the thermostat or water pump, is typically the solution.

Electrical System
1. Electrical Gremlins:
- Possible Causes: The 1998 320E can be susceptible to electrical gremlins, often stemming from aging wiring harnesses, faulty relays, or a failing battery.
- Troubleshooting: A multimeter can be your best friend here, allowing you to test circuits for continuity and voltage.
- Solutions: Repairing or replacing damaged wiring, relays, or the battery itself is often necessary.
2. Sensor Issues:
- Possible Causes: The mass airflow sensor (MAF), crankshaft position sensor, and camshaft position sensor are known to cause issues in this model.
- Troubleshooting: A diagnostic tool, like those offered by CARDIAGTECH, can read error codes and pinpoint the problematic sensor.
- Solutions: Replacing the faulty sensor is the most reliable fix.
