Cooling System Overhaul Necessity: The plastic and rubber components of the cooling system (radiator, expansion tank, hoses, thermostat housing) become brittle and weak over time. Failure to regularly replace these parts leads to overheating, which can damage the engine, especially the aluminum heads.
Oil Leaks (M30, M60, M70): All engine variants commonly suffer from oil leaks. The most typical sources include:
Valve Cover Gasket (VCG): Common on M30 and M70.
Oil Pan Gasket: Especially difficult to replace on V8 and V12 models.
Timing Cover Gaskets.
M70 (V12) Specific Issues: Since the M70 essentially combines two M30 six-cylinder engines, maintenance is complex and expensive. Common issues include:
Dual Idle Control Valves (ICVs): Prone to sticking, causing rough idle.
Vacuum Leaks: The extensive vacuum system can develop leaks, affecting engine performance.
Steering Box/Steering Gear Slop: The E32 uses a recirculating ball steering box, which can develop play or "slop" over time, leading to vague or imprecise steering feel. Adjustment or replacement is often necessary.
Suspension Bushings and Mounts: All rubber bushings (control arms, trailing arms, sway bar links) are sacrificial items and degrade with age, causing clunking sounds, instability, and poor handling.
Self-Leveling Suspension (SLS): Found on some high-end models (especially the 750iL), this hydraulic system uses mineral oil (Pentosin). Leaks in the system, failure of the hydraulic spheres (accumulators), or pump issues are common and expensive to fix.
Automatic Transmission (ZF): The ZF automatic transmissions used (e.g., 4HP22/24) are generally robust but require regular fluid and filter changes. Neglect leads to hard shifts or eventual failure. The kickdown cable adjustment is also critical for shift quality.
Driveshaft Flex Disc (Guibo) and Center Support Bearing: These rubber components perish with age and contribute to vibration and clunking during acceleration or shifting.
Rust (Wheel Arches and Jack Points): Rust is a significant issue, particularly around the rear wheel arches, rocker panels (sills), and the factory jacking points, especially in regions with road salt.
Sunroof Drain Clogs: Clogged drains can cause water to back up and leak into the interior, potentially damaging carpeting and interior electronics.
Door and Trunk Seals: The rubber seals harden over time, leading to wind noise and water leaks into the cabin or trunk.
