• Range Rover Vogue

Signs and symptoms

If you own a Range Rover P400e, you might experience one of the following signs of charging problems:

• Inability to Hold Charge: Your vehicle’s battery may not hold a charge for as long as it should. This could result in various electrical issues, including difficulty starting the car, dimming lights, and more.
• Decreased Range: You may notice a decrease in the car’s electric range. This happens when the electric motor doesn’t receive enough power from the battery.
• Charging Malfunction: At times, you may plug in your car to charge it, but it won’t accept the charge.

List of possible OBD codes

If you’re experiencing charging problems, the first step in diagnosing the problem is checking for any trouble codes.

Here are some possible OBD codes:

• P0C2B– Invalid Data Received from Onboard Charger Control Module.
• P0C2C– Battery Pack Control Module “A” Temperature Sensor Circuit.
• P0C2D– Battery Pack Control Module “B” Temperature Sensor Circuit.
• P0C2E– Battery Pack Control Module “C” Temperature Sensor Circuit.

Common causes

Several issues could cause the charging problems you are facing.

Some of the most common ones include:

• Software Glitches: The Range Rover P400e’s complex electrical system is not immune to software glitches. Some glitches could compromise the vehicle’s ability to charge.
• Faulty Charging Components: A faulty charger, DC/DC converter, or battery temperature sensor could affect the vehicle’s charging capabilities.
• Battery Issues: If your car battery is aging or has a faulty cell, it won’t hold a charge as well as it used to.

Can it be fixed without a mechanic?

Some charging problems can be fixed without visiting a mechanic, depending on the severity of the issue. If you’re dealing with software glitches or the charging cord’s loose connection, you may find solutions without professional help.

However, suppose the problem is more severe, like a mechanical component failure. In that case, consulting a professional mechanic is the best course of action.

Parts you’ll need to fix it

Here’s a list of parts you might need to replace to fix your Range Rover P400e charging problems:

• OEM Charger
• DC/DC Converter
• Battery Temperature Sensor
• Hybrid Battery Pack
• Battery Meters
• Battery Charger Cable

Tools you’ll need to fix it

If you’re planning to work on the Range Rover P400e charging system, you’ll need the following set of tools:

• Torque Wrench
• Digital Multimeter
• Cold Temperature Heat Gun
• Soldering Iron and Solder Wires
• Car Battery Monitor
• A set of Screwdrivers and Pliers

How to fix it

Here is a step-by-step guide on how to fix your Range Rover P400e charging problems:

1. Check the Charging Cord: Ensure that the charging cord is firmly connected to the car and the power source.
2. Inspect the Charger: Check the OEM charger for any signs of damage, frayed wires, or malfunctioning.
3. Check the DC/DC Converter: If the DC/DC converter is faulty, disassemble it and check the PCB for any burnt-out chips or components and replace them as necessary.
4. Inspect the Battery Pack: Check the battery pack for any signs of damage or wear, such as corrosion, cracks, or leaks. Replace any faulty or worn-out parts.
5. Inspect the Battery Temperature Sensor: Check whether the battery temperature sensor is faulty and replace it as necessary.
6. Check the Battery Meter: If the battery meter isn’t working correctly, take a cold temperature heat gun and measure the resistance and voltage of the battery.
7. Check the Car Software: Use a digital multimeter to ensure that the car software is not causing any problems by checking for voltages.
8. Test the Battery: Charge the battery to 100% and then use a car battery monitor to test it.
9. Reassemble the Car: Reattach any parts that were removed from the car during the fixing process.

Potential alternative causes

Aside from the common causes mentioned above, some lesser-known reasons could cause Range Rover P400e charging problems.

Some possible causes are:

• Issues with Brake Light Switches causing the car not to recognize that the brake is being pressed before engaging the charge mode.
• The Exhaust Gas Particulate Filter (GPF) causes a sensor to detect increased resistance in the battery.
• A fault in the charge point system, caused a glitch when charging the car.
