If you own a Range Rover, you may have experienced the frustration of your vehicle suddenly going into limp mode.
Limp mode is a safety feature designed to protect your engine and transmission from further damage when an incorrect parameter is received from the engine or transmission control unit.
When this happens, your car’s performance is significantly reduced, and it may feel like it is struggling to accelerate or reach its top speed.
In specific Range Rover models, a warning light may appear saying reduced engine performance or restricted performance.
What is limp mode?
If you own a Range Rover, you may have heard of “limp mode.” Limp mode is a safety feature that protects your engine and transmission from further damage when a fault is detected in the system.
When a fault is detected, the car activates limp mode to minimize damage to the engine and transmission.
When your Range Rover goes into limp mode, the car’s computer will limit the engine’s power and speed.
This means that you will not be able to accelerate as quickly as you normally would, and your car may struggle to reach high speeds.
Limp mode is designed to give you enough time to get your car to a mechanic or a safe location.
There are many reasons why your Range Rover may go into limp mode. Some common causes include:
- Low levels of oil or coolant
- Transmission errors
- AC compressor issues
- Electronic control unit (ECU) malfunctions
- Scanner communication problems
It’s very obvious when your Range Rover is in limp mode, but you should take it to a mechanic as soon as possible. A mechanic should be able to diagnose and fix the problem before it causes further damage to your car.
They will use an OBD scanner to read the fault codes and determine the cause of the problem.
Overall, limp mode is an important safety feature that protects your Range Rover from further damage when a fault is detected in the system.
If you suspect your car is in limp mode, don’t hesitate to take it to a mechanic. They will be able to diagnose and fix the problem before it causes further damage to your car.
Common causes of limp mode in Range Rovers
If you own a Range Rover, you may have experienced limp mode, which is a security measure that reduces engine power to prevent further damage to the vehicle. Here are some of the most common causes of limp mode in Range Rovers:
Transmission issues
Transmission problems are a common cause of limp mode in Range Rovers. If your transmission control unit detects an issue with the transmission system, it may activate limp mode to prevent further damage.
Some common transmission issues include low transmission fluid levels, faulty transmission sensors, and issues with the throttle position sensor.
Range Rover Evoque-specific issues
Range Rover Evoque owners may experience limp mode due to specific issues during their ownership.

Some of the most common issues include blocked fuel filters, contaminated fuel, and issues with the electric steering pump.
Fuel system issues
Issues with the fuel system can also cause limp mode in Range Rovers.
If your engine control unit detects a problem with the fuel system, it may activate limp mode to prevent further damage.
Some common fuel system issues include low oil levels, blocked fuel filters, and contaminated fuel.
Brake system issues
Faulty brake systems can also cause limp mode in Range Rovers.
If your vehicle detects an issue with the brake system, it may activate limp mode to prevent further damage.
Some common brake system issues include hydraulic leakage, low brake fluid levels, and faulty brake systems.
Turbo and intercooler issues
Issues with the turbo and intercooler can also cause limp mode in Range Rovers.
If your engine control unit detects an issue with the turbo or intercooler, it may activate limp mode to prevent further damage.
Some common issues include split turbo hoses, issues with the turbo boost pressure, and issues with the intercooler.
If your Range Rover goes into limp mode, it is important to have it checked by a mechanic who can use a scanner to diagnose the issue.
It is also important to keep up with regular maintenance, such as checking your oil and fluid levels, to prevent issues that can cause limp mode.
How to fix limp mode in Range Rovers
If you’re experiencing limp mode in your Range Rover, don’t panic. There are several DIY solutions you can try before calling a mechanic.
However, it’s important to note that some issues may require professional help.
This section will cover the diagnostic tools and error codes, common DIY solutions, and when to call a mechanic.
Diagnostic tools and error codes
The first step in fixing limp mode is to determine the cause of the problem. You can use an OBD2 scanner to check for error codes.
These scanners are available online or at most auto parts stores.
Once you have the error codes, you can determine the cause of the problem.
Some common causes of limp mode include:
- Throttle position sensor issues
- Low engine oil levels
- Faulty engine sensors
- Blocked fuel filter
- Faulty brake system
- Split turbo hose
- Contaminated fuel
- Transmission control unit issues
It’s important to note that error codes can vary depending on the model and year of your Range Rover.
Check your owner’s manual or consult a forum for more information.
Common DIY solutions
If you’ve determined the cause of the problem and it’s a minor issue, there are several DIY solutions you can try:
- Check your engine oil levels and top up if necessary
- Replace your air filter
- Clean your throttle body
- Replace your fuel filter
- Check your battery and replace if necessary
- Check your transmission fluid levels and top up if necessary
Again, it’s important to note that these solutions may not work for all cases of limp mode. If you’re unsure or the problem persists, it’s best to consult a mechanic.
When to call a mechanic
If you’ve tried the DIY solutions and the problem persists, it’s time to call a mechanic. Some issues may require specialized equipment or knowledge to fix.
Some examples include:
- Transmission issues
- Brake system issues
- Turbo and intercooler issues
