The LCD display (odometer, trip computer, service indicator) becomes faded, spotty, or partially blank. Individual pixel rows may drop out.

Cause

The ribbon cable connections between the LCD module and the cluster circuit board develop dry solder joints from thermal cycling.

Fix

Re-solder the ribbon cable connections.

Repair kits with replacement ribbon cables are available for $20-50.

The repair requires removing the cluster and basic soldering skills.

A specialist can do it for $100-200.

Common Engine, M50/M52 (320i, 325i, 328i)

VANOS Seal Failure

Rattling or clattering noise from the front of the engine on cold start, lasting 10-30 seconds before fading as oil pressure builds. Loss of low-end torque, the engine feels flat below 3,000 rpm and only comes alive higher in the rev range. In severe cases, rough idle and a general feeling that the engine is "lazy" at low speeds.

Critical Engine, M50/M52 (320i, 325i, 328i)

Cooling System Failure, Expansion Tank

The plastic expansion tank cracks, often along a moulding seam or at the neck where the cap seals. Coolant pours out rapidly. The engine overheats within minutes if the driver doesn't notice the temperature gauge climbing.

Critical Engine, M50/M52 (320i, 325i, 328i)

Cooling System Failure, Water Pump

Engine temperature gradually rises above normal, or suddenly overheats. Coolant leak from the water pump area. In some cases, no external symptoms, the plastic impeller simply disintegrates inside the pump housing, and broken plastic fragments circulate through the cooling system, blocking the heater core and radiator passages.
