Issues with the DBS system can lead to inconsistent or unreliable braking assistance, particularly in emergency situations.

The supercharger, being an additional component in the engine, can experience wear and tear, leading to reduced performance, unusual noises, or potential failure.

The AJ126 engine has been known to have issues with the timing chain tensioner, which can lead to engine knocking noises and, if not addressed, severe engine damage.

The V-shaped engine configuration can sometimes be prone to coolant leaks, which can cause overheating and potential engine damage if not properly maintained.

This engine model can experience problems with the fuel injectors, leading to misfires, rough idling, and reduced fuel efficiency.

Modern Land Rover vehicles, including the 2018 Discovery, often experience issues with their electronic control systems, which can cause various engine performance issues and warning lights.

If the engine variant includes a turbocharger, it may suffer from issues such as oil leaks, reduced boost pressure, or complete failure, affecting overall engine performance.

The AJ126 engine in some instances may suffer from oil dilution, where fuel mixes with the engine oil, reducing its lubricating properties and leading to increased engine wear.

Problems with the crankshaft sensor can lead to difficulties in starting the engine, engine stalling, or erratic engine behavior.

Direct injection engines, like the AJ126, can experience carbon buildup on intake valves, leading to reduced performance, rough idling, and possible engine misfires.

The Jaguar AJ126 engine is known to have issues with oil leaks, particularly around the valve covers and oil pan gasket.

Since the engine is supercharged (S/C), problems with the supercharger such as bearing failure or belt issues could arise, affecting performance.

The timing chain tensioner on the AJ126 engine can wear out prematurely, causing timing issues and potentially severe engine damage.

The cooling system, including the water pump and radiator, may develop leaks or fail, leading to overheating issues.

Direct-injection engines like the AJ126 can suffer from carbon build-up on the intake valves, which can affect performance and fuel efficiency.

The ignition coils on this engine are prone to failure, which can cause misfires and rough running conditions.

The engine mounts can wear out, leading to increased vibrations and noise from the engine bay.

Various sensors, such as the mass airflow sensor (MAF) and oxygen sensors, can fail, leading to poor engine performance and diagnostic trouble codes.

The 2019 Jaguar F-TYPE with the AJ126 engine may experience overheating due to its high-performance nature and supercharged configuration, which can place extra stress on the cooling system.

The V-shaped configuration of the AJ126 engine can sometimes lead to oil leaks, particularly around the valve covers and oil pan gaskets.

The supercharged (S/C) setup can develop problems with the supercharger itself, such as bearing wear or belt issues, leading to reduced performance.

The AJ126 engine has been known to have issues with timing chain tensioners, which can lead to timing chain slack and potential engine damage if not addressed.

Engine misfires can occur due to faulty ignition coils or spark plugs, which are common issues in many high-performance engines like the AJ126.

The direct injection system in this engine can sometimes lead to clogged or malfunctioning fuel injectors, affecting engine performance and efficiency.

Components such as the water pump, radiator, and thermostat can fail, leading to inadequate cooling and potential engine damage.

The complex electronics and sensors in the AJ126 engine can sometimes fail or give incorrect readings, leading to performance issues or check engine lights appearing.
