Problems:
Dynamic brake support (dbs) malfunction
Issues with the DBS system can lead to inconsistent or unreliable braking assistance, particularly in emergency situations.
Supercharger (s/c) problems
The supercharger, being an additional component in the engine, can experience wear and tear, leading to reduced performance, unusual noises, or potential failure.
Timing chain tensioner 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.
Coolant leaks
The V-shaped engine configuration can sometimes be prone to coolant leaks, which can cause overheating and potential engine damage if not properly maintained.
Fuel injector issues
This engine model can experience problems with the fuel injectors, leading to misfires, rough idling, and reduced fuel efficiency.
Electronic control system faults
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.
Turbocharger (if applicable) failure
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.
Oil dilution
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.
Crankshaft sensor failure
Problems with the crankshaft sensor can lead to difficulties in starting the engine, engine stalling, or erratic engine behavior.
Excessive carbon buildup
Direct injection engines, like the AJ126, can experience carbon buildup on intake valves, leading to reduced performance, rough idling, and possible engine misfires.
