Range Rover MOT Failures: Air Suspension and Bushes
Quick Answer
Range Rovers (L322 and L405) most commonly fail their MOT on air suspension leaks, worn rear lower arm bushes, electric handbrake faults, contaminated brake fluid and headlight aim. Repairs are high-AOV: a single air spring is £250-450 fitted and a full air suspension overhaul can exceed £2,000.
The Range Rover is one of the most expensive cars in the UK to repair at MOT time, and L322 (2002-2012) and L405 (2013-2021) examples both have known weak points. A free MOT history check before buying any used Range Rover is essential to avoid hidden bills.
Air spring leaks on L322 and L405
Air suspension is standard on every Range Rover from the L322 onward, and air spring failure is the single most common high-cost MOT issue. A leaking spring causes the car to sink overnight on one corner, triggers the suspension warning, and is a major fail under DVSA Inspection Manual Section 5.3.1.
Genuine Continental air springs cost £250-450 fitted per corner, and Arnott aftermarket conversions £180-320. Owners with leaks on multiple corners often opt for a full set replacement at £900-1,400 to avoid repeat work.
Rear lower arm bushes and watt linkage
L405 rear lower control arm bushes wear at 60,000-80,000 miles, causing a loose feel under braking and noticeable play that fails Section 5.3.4. The watt linkage central pivot is another wear point unique to the L405 platform.
Lower arm replacement is £350-550 per side fitted at a Land Rover specialist. Watt linkage refurbishment is around £400-650. These are high-AOV jobs that owners are often surprised by at MOT time.
Electric handbrake faults
The electric parking brake on L322 and L405 uses motors integrated into the rear callipers. When a motor fails or the actuator sticks, the brake test imbalance becomes a major fail under Section 1.4.2.
Replacement callipers with integrated motors run £450-750 per side at an independent. Module reset and recalibration after fitting requires diagnostic equipment, adding £60-100 in labour.
Brake fluid contamination
Range Rover brake systems run hot under heavy use, and fluid moisture content rises faster than on smaller cars. Since 2018 the MOT has tested fluid with a refractometer, and contamination above 3% moisture is a major fail.
A full brake fluid flush at a Land Rover specialist is £80-140, well below dealer rates. Land Rover's recommended interval is every two years.
Headlight aim and LED faults
L405 adaptive LED headlights are highly capable but cannot be DIY-adjusted, and aim drift after off-road use or kerb knocks is common. Aim adjustment is £20-40, but a failed LED module is an eye-watering £1,200-2,200 per side.
If only a single LED segment has failed, some specialists offer module repair at £350-600, which is far cheaper than full replacement.

How to prepare a Range Rover for the MOT
Always book at a Land Rover specialist rather than a chain garage. Parking the car overnight on level ground tests for any air leaks: any sink at one corner is a clear warning. Pull your MOT history check for prior advisories.
If buying second-hand, combine the MOT history check with a finance check and a stolen check to fully de-risk the purchase.
Frequently Asked Questions
How much does Range Rover air suspension cost to fix at MOT?
A single air spring is £250-450 fitted, and a full overhaul of all four corners £900-1,400 at an independent specialist. Dealer pricing is roughly double.
Can a Range Rover pass an MOT with a sagging corner?
No. A leaking air spring or sagging corner is a major fail under DVSA Inspection Manual Section 5.3.1. The system must hold pressure for the test to pass.
Are L322 or L405 more reliable for MOTs?
L405 (2013-2021) generally has fewer compound failures than L322 but more expensive parts. L322s often need cumulative work that approaches the car's value.
Does the Range Rover electric handbrake fail often?
The motor-in-calliper design fails at 70,000-100,000 miles, often as one side first. This causes a brake test imbalance and is a major MOT fail until replaced.
Should I buy a Range Rover with no MOT history?
Always run a free MOT history check before purchase. Range Rovers without recent test history often hide expensive air suspension or transmission issues.
Range Rover MOT bills can be eye-watering, but a pre-purchase or pre-test check catches most issues early. Run a free MOT history check before booking or buying.
