How to reset air suspension on Range Rover

Introduction

The Range Rover, also known as Land Rover Range Rover, is a 4x4 motor car produced by the Land Rover Company. This Company is a sub-brand of the Jaguar Land Rover car which was started in 1970 by British Leyland Motors. This vehicle is in its fifth generation now and there are other models under the name, Range Rover. These models include Range Rover Sport, Range Rover Evoque, and Range Rover Velar.

Having changed ownership a few times, the Land Rover Range Rover firm now belongs to the Indian auto manufacturing giant, Tata Motors. 

The fifth generation Range Rover was launched on the 26th of October 2021 by the Royal Opera House in London. It was launched by the Motor Company's Chief Creative Officer and car designer, Gerry McGovern. The vehicle has two PHEVs, three diesel, and two petrol JLR 3.0 L Ingenium I6 engine options. And it will be the first from JLR to use an engine developed under the combustion and electrified powertrain partnership agreed upon between JLR and BMW in 2019, as a 4.4L BMW/JLR V8 engine is also an option. The car was unveiled with a range of mild hybrid diesel and petrol engines, with plug-in hybrids due in early 2022 and an all-electric model in 2024.

The Range Rover, with an air suspension system installed into it, has numerous advantages, features & benefits and they include; an adjustable leveling control, elimination of sagging,  safer carriage of loads, better brake application, improved steering and handling on the road,  stabilization of body roll,  excellent ride on the road, reduced wear and tear of tires, and a lower cost of maintenance.

In addition, the Land Rover Range Rover, because of advancement in car technology will be introducing a new and innovative advancement on the Discovery Sport. This innovation is a pedestrian airbag designed to protect anyone, unavoidably, hit by a vehicle while crossing the road. The airbag works when its sensors, situated below the exterior of the front bumper, detect the impact with a crossing pedestrian. The vehicle moving 24 and 48 kilometers per hour has its sensors detect impact, and the airbag often hidden behind a panel below the windshield deploys itself in 60 milliseconds.

Range Rover Problems

The Range Rover, though a choice and luxury car, has its problems. Every owner of this vehicle knows that it commands attention, interest, and adoration, however, it has its flaws for which it's criticized. It's criticized for its problems because every customer wants optimal value for the products they buy. If you own a Range Rover that gives you problems and you seek solutions to them, this article is for you.

The most common problem of the Range Rover cars is the suspension system. The Range Rover suspension system, though designed to give a smooth ride on the road has a fault, it fails. This failure gives a jarring and uncomfortable ride. At times, the suspension system can completely fail, stranding you in the middle of nowhere especially when traveling. Other Range Rover suspension faults are:

  • Airbag Fault
  • Airbags are pivotal to the Range Rover suspension system. The airbags, over time, can develop leaks. These leaks are caused by the rubber of which it's made losing its strength because of the age or serviceability of the car. 

  • Height Problems
  • This is also a problem confronting owners of the luxury Range Rover. The height sensors are designed and installed into the vehicle to measure the vehicle's distance from the ground. The sensors sit on four corners in proximity to the airbags. The sensors are damaged by the vehicle's exposure to rough terrains or harsh weather. And loose and damaged sensors can cause a suspension system to sag.

  • Electronic Problems
  • These problems stem from your control panels or frayed wires. I suggest you consult a professional Mechanic who can solve this problem.

  • Jacking
  • A saggy air suspension system in a Range Rover is difficult to jack. The car becomes lowered. It moves at a snail's pace because there's nothing to withstand the weight of the car.

    • Air Compressor 

    Air compressors fail after many years of use. This causes air shortage in and through the system. It will cause an error message to appear.

    Now that you're aware of air suspension problems in the Range Rover car, let me discuss with you how to reset the air suspension on Range Rover.

    How to Reset Air Suspension on Range Rover

    If your Range Rover gives you uncomfortable driving on the road, these solutions are for you. There're two ways by which you can reset the air suspension in your Range Rover. 

    Understanding Air Suspension Issues

    Air Suspension Inactive Message: This common alert signals potential problems within the system.

    Low or Uneven Ride Height: You might notice the vehicle sitting lower than usual or displaying an uneven ride height across different sides.

    Mechanical Faults: Issues may arise from airbag leaks, worn compressors, faulty sensors, or electrical complications.

    Resetting Your Range Rover's Air Suspension

    1. Steering Wheel Reset Method

    • Start your Range Rover, ensuring it is in park and the parking brake is engaged.
    • Fully turn the steering wheel to the left, then fully to the right. This lock-to-lock motion can sometimes clear basic 'Air Suspension Inactive' warnings.

    2. Adjusting Ride Height

    • Utilize the air suspension controls to elevate the vehicle to its highest setting.
    • Then lower it completely to the ground.
    • Repeat this adjustment several times to aid system recalibration.

    3. Using an OBDII Diagnostic Tool

    • Attach an OBDII scanner to the diagnostic port of your Range Rover.
    • Scan for any fault codes that pertain to the air suspension system.
    • Use the scanner to clear any detected fault codes, potentially resetting the system.

      Solutions For A Faulty Range Rover Air Suspension

      If the above methods fail and you notice issues in driving dynamics, it's time to further diagnose the problem.

      How To Tell If Your Range Rover Has Suspension Problems

      A clear sign of trouble is the suspension fault light on the dashboard; if this light is activated or if there are error messages, take them seriously. Observe how your Range Rover sits when parked; an uneven stance can suggest underlying issues. Pay attention to the vehicle’s handling and ride quality while driving. A deterioration in handling or an increase in bumpiness can point to problems such as damaged air springs or a failing compressor. Additionally, if your Range Rover struggles to maintain its height, particularly after extended driving or when carrying different loads, it's likely time for a suspension check.

      How To Fix A Broken Range Rover Air Suspension

      Addressing a broken air suspension system in your Range Rover requires some technical know-how, but it's manageable. Start by pinpointing the problem using a diagnostic tool to retrieve fault codes. For air leaks, often found in the air bags or the valve block, replacing the defective parts typically resolves the issue. If the compressor is faulty, consider replacing it entirely or use compressor repair kits for minor issues. Issues related to sensors and electronics might necessitate professional repair. Some tasks, such as replacing individual struts or valves, can be accomplished with basic tools. It’s essential to ensure that the vehicle is level and stable during any repairs to the suspension, to avoid further complications.

      Aftermarket Parts: A Better, Cheaper Fix For Your Range Rover Suspension

      For a more economical solution to Range Rover suspension issues, consider consulting a specialized mechanic and purchasing parts independently. Many mechanics with expertise in Land Rover suspensions have the necessary tools and charge less than dealerships. You can further reduce expenses by buying your own parts. Explore aftermarket Range Rover air suspension options, where you can find compressor repair kits, struts, and other key suspension components that will help your vehicle ride smoothly without the hefty dealership price tag.
