Most likely causes
- Faulty supercharger
- Oil leaks
- Wiring issues
- Failed sensors
- Failed actuators
Can it be fixed without a mechanic?
In many cases, yes. However, it’s important to note that some problems may require professional diagnosis and repair.
Parts you’ll need
- Supercharger
- Oil leaks: oil pan gasket, valve cover gasket, etc.
- Sensors
- Actuators
- Wiring
Tools you’ll need
- OBD scanner
- Multimeter
- Wiring diagrams
- Basic hand tools (screwdrivers, pliers, etc.)
How to fix it
- Use an OBD scanner to diagnose the issue and retrieve the OBD codes
- Check wiring and connections for damage or loose connections
- Replace any faulty sensors or actuators
- Replace the supercharger if necessary
- Fix any oil leaks by replacing the necessary gaskets or seals
Potential other alternative causes
Failed turbocharger
A failed turbocharger can cause a variety of problems for the supercharged engine. The turbocharger is responsible for increasing the amount of air that enters the engine, which in turn increases power and performance. When the turbocharger is not functioning properly, it can cause a loss of power, poor engine performance, and even stalling.
Additionally, a failed turbocharger can cause the “check engine” light to come on and may also trigger diagnostic trouble codes (DTCs).
Clogged air filter
A clogged air filter can cause problems for the supercharged engine. The air filter is responsible for removing contaminants from the air before it enters the engine. When the air filter is clogged, it can cause the engine to run lean (not enough air), which can lead to poor engine performance, stalling, and even damage to the engine.
Additionally, a clogged air filter can cause the “check engine” light to come on and may also trigger diagnostic trouble codes (DTCs)
Low oil pressure
Low oil pressure can cause a variety of problems for the supercharged engine. Oil pressure is necessary for the engine to function properly. If there is low oil pressure, it can cause a loss of lubrication which can lead to engine damage.
Additionally, low oil pressure can cause the “check engine” light to come on and may also trigger diagnostic trouble codes (DTCs). If the low oil pressure is caused by a damaged or worn oil pump, it can lead to severe engine damage if not addressed quickly.
Summary
The Range Rover Sport Supercharged engine is a powerful and capable engine, but it is not immune to common problems. Some of the most common issues include a faulty supercharger, oil leaks, and problems with the engine’s electronic control system. It’s important to diagnose the issue using an OBD scanner and use wiring diagrams to check connections and replace any faulty parts. In many cases, the issue can be fixed without a mechanic.

Hello, does a super charger wet spark plugs with oil if its had its dayz?
Hi Siya,
I would get that immediately looked at. Wet spark plugs (never mind oil) is never a good sign.
My L494 is showing E Diff not available, just after a car wash. What could be the issue.
