AIR BAGS:SIDE/WINDOW
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THESE VEHICLES ARE BUILT WITH A SIDE AIR BAG SYSTEM CONSISTING OF DOOR-MOUNTED THORAX AIR BAGS (REAR DOOR AIR BAGS ARE OPTIONAL), A CENTRAL ELECTRONIC SENSOR AND DIAGNOSTIC SYSTEM, LEFT AND RIGHT SATELLITE IMPACT SENSORS, AND ASSOCIATED WIRING. THIS SYSTEM IS UNDULY SENSITIVE TO CERTAIN NON-CRASH IMPACTS, SUCH AS CONTACTING LARGE POTHOLES OR CURBS AT SUBSTANTIAL SPEED.
VEHICLE SPEED CONTROL
THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING. IT IS POSSIBLE THAT THE PLASTIC BUSHING ON EITHER CABLE COULD BREAK DUE TO ENVIRONMENTAL INFLUENCES COUPLED WITH VIBRATION. IF THE BUSHING BREAKS, THE OUTER CABLE HOUSING CAN SEPARATE FROM THE BUSHING. IN THIS CASE, DURING APPLICATION OF THE THROTTLE PEDAL WITHOUT CRUISE CONTROL BEING ENGAGED, THE OUTER TUBE COULD CATCH ON THE EDGE OF THE BROKEN BUSHING.
ENGINE AND ENGINE COOLING:COOLING SYSTEM
VEHICLE DESCRIPTION: PASSENGER VEHICLES. A MALFUNCTION OR FAILURE OF A COOLANT SYSTEM COMPONENT, SUCH AS A THERMOSTAT, WATER PUMP, OR FAN BELT, CAN RESULT IN SIGNIFICANTLY INCREASED COOLANT TEMPERATURE AND SYSTEM PRESSURE. IF THE INDICATIONS OF A CRITICAL OVERHEATING CONDITION IS NOT NOTICED BY THE DRIVER, IT IS POSSIBLE THAT DAMAGE TO, OR FAILURE OF, A COOLANT SYSTEM COMPONENT COULD OCCUR.

The E36 chassis routes rear-suspension loads from the subframe mounts through thin sheet-metal of the rear axle carrier panel (trunk floor). On hard-driven, tracked, or high-mileage M3s the metal around the subframe mounting points fatigues and cracks, sometimes tearing the floor… Repairs typically run $800-$3,000. Severity: high.
The US-spec S52B32 engine (1996-1999) uses a single-VANOS variable camshaft timing unit whose internal seals and the mechanical coupling between the cam gear and VANOS shaft wear out with age and mileage. Degraded seals bleed off oil pressure and worn splines/axial play produce a… Repairs typically run $150-$1,500. Severity: medium.

The rear trailing arm bushings (RTAB) locate the rear trailing arms to the chassis and control rear toe under load. On the E36 they wear and crack with age, allowing rear toe to change under acceleration and braking and producing a loose, disconnected rear-end feel. Engine/transm… Repairs typically run $250-$900. Severity: medium.
S50/S52 M3s commonly consume oil with no external leaks and no visible exhaust smoke, typically in the range of about a half-quart to two quarts per 3,000 miles. The primary contributors are a failing crankcase ventilation valve (CCV/oil separator) that pulls oil vapor into the i… Repairs typically run $150-$700. Severity: medium.
E36 window regulators use plastic slide clips and cable/lift mechanisms that fail with age, causing windows to bind, jam, or drop into the door. It is one of the most common E36 electrical/mechanical annoyances. Alongside it, the M3 interior develops well-known rattles from crack… Repairs typically run $150-$400. Severity: low.
