The Intermediate Shaft (IMS) bearing can fail, which may lead to catastrophic engine damage if not addressed. This is a known issue in Porsche engines of this era.

Cooling system issues

The Boxster can experience problems with the water pump and the coolant reservoir, leading to potential overheating.

Rms (rear main seal) failure

The rear main seal can develop leaks, causing oil to drip and potentially leading to clutch contamination.

Air-oil separator failure

A faulty air-oil separator can lead to excessive oil consumption and smoke from the exhaust.

Fuel system problems

Issues with the fuel injectors and fuel pump can lead to poor engine performance and starting problems.

Problems:

Oil leaks

The 2009 BMW 535i with a 6-cylinder engine is prone to oil leaks, often from the valve cover gasket or the oil filter housing gasket.

High-pressure fuel pump failure

The high-pressure fuel pump (HPFP) is known to fail, causing issues such as long cranks, misfires, and reduced power.

Turbocharger failure

Turbochargers in this model can fail prematurely, leading to poor performance and increased exhaust smoke.

Cooling system problems

Issues with the water pump and thermostat are common, which can cause overheating and potential engine damage.

Carbon buildup

Direct injection engines like the one in the 535i can suffer from carbon buildup on the intake valves, leading to rough idling and reduced performance.

Electric water pump failure

The electric water pump can fail, leading to cooling system issues and possible engine overheating.

Vanos solenoid failure

The Variable Valve Timing (VANOS) solenoids can fail, leading to poor engine performance and rough idling.

Engine misfires

Misfires can be caused by faulty ignition coils, spark plugs, or fuel injectors.

Timing chain issues

The timing chain and its components can wear out prematurely, leading to potential engine damage if not addressed.

High-pressure fuel pump (hpfp) failure

The high-pressure fuel pump on this model is known to fail, leading to issues such as engine stalling, long cranking times, and reduced performance.

Injectors issues

Fuel injector problems can lead to rough idling, misfires, and poor fuel economy.

Carbon build-up

Direct injection engines like the one in the 335i are prone to carbon build-up on the intake valves, which can cause rough idling, misfires, and power loss.

Water pump and thermostat failure

The electric water pump and thermostat in the 335i often fail, leading to overheating issues.

Oil leaks

The valve cover gasket and oil filter housing gasket are known to develop leaks, causing oil to seep out and potentially damage other engine components.
