Problems:

Oil leaks

Due to the complexity of the V8 engine, oil leaks can occur from various seals and gaskets, such as the valve cover gaskets or oil pan gaskets.

Timing chain issues

The BMW V8 engines, especially in the 750Li, are known for timing chain guide failures, which can lead to significant engine damage if not addressed.

Coolant leaks

The 2014 BMW 750Li and ALPINA B7 can experience coolant leaks from components like the water pump, radiator, and hoses.

Fuel injector problems

Over time, the fuel injectors can become clogged or fail, leading to rough idling, misfires, and poor engine performance.

Turbocharger issues

In the ALPINA B7, the turbochargers can fail due to high heat and stress, leading to reduced engine performance and possible engine damage.

Carbon build-up

Direct injection engines, such as those in the 750Li and ALPINA B7, can suffer from carbon build-up on the intake valves, reducing performance and efficiency.

High-pressure fuel pump (hpfp) failure

The HPFP can fail, leading to starting issues, rough idling, and stalling.

Vacuum leaks

Vacuum leaks from hoses and connections can cause rough idling, poor acceleration, and engine performance issues.

Electronic throttle body issues

Problems with the electronic throttle body can lead to poor throttle response and reduced engine performance.

Sensor failures

Various sensors (e.g., oxygen sensors, mass airflow sensors) can fail, leading to check engine lights and reduced performance.

BMW 750i / ALPINA B7 2014

Problems:

Oil leaks

BMW engines, particularly V8 engines, are known for developing oil leaks over time. This is often due to deteriorating gaskets and seals.

Timing chain issues

The timing chain can become loose or stretched, leading to poor engine performance and potentially severe engine damage if not addressed.

Fuel injector problems

Fuel injectors can get clogged or fail, causing misfires, poor fuel economy, and rough idling.

Carbon build-up

Direct injection engines are prone to carbon build-up on the intake valves, which can lead to reduced engine performance and increased fuel consumption.

Cooling system failures

Components like the water pump, thermostat, and radiator can fail, leading to overheating and potentially severe engine damage.

Turbocharger failure (alpina b7)

The turbocharged engine in the ALPINA B7 model may suffer from turbocharger issues, such as bearing failure or wastegate problems.

Electrical issues

BMWs often face electrical problems, including issues with sensors, wiring, and control modules that can affect engine performance and diagnostics.

Vanos (variable valve timing) issues

Problems with the VANOS system can cause rough idling, loss of power, and increased emissions.
