Jaguar & Land Rover Diagnostics & Repairs

A warning light tells you something is wrong. Finding out exactly what takes Jaguar Land Rover-trained technicians, the JLR diagnostic systems we have as part of the Jaguar Land Rover network, and the patience to look properly. That is what we do, then we repair it here with genuine parts. Accurate diagnosis is one of the things JLC is best known for.

Book a diagnostic assessment

Call 0333 358 4434, or request a callback and we will ring you within 24 hours, Monday to Friday. Loan cars, collection and delivery and a complimentary chauffeur are available.

Diagnosis is a clear fixed price. Any repair that follows is quoted, and nothing goes ahead until you have approved it.

How we work

Official JLR diagnostics

As part of the Jaguar Land Rover network, we diagnose your car with JLR’s diagnostic systems, technical information and live data, and with direct access to JLR technical support. Every investigation follows the Jaguar Land Rover procedure for your exact car.

Beyond the fault code

Reading a fault code is easy. Understanding it takes training, experience and the right information. Our technicians follow Jaguar Land Rover’s own diagnostic procedures, so you only pay for the parts your car actually needs.

Clear findings and a quotation

Once we have found the cause, we explain what it is, what it will take to put right and exactly what it will cost, so you can decide before any further work goes ahead.

Repaired in-house

Mechanical, electrical, software and high-voltage repairs are all done in our own Sevenoaks workshop by Jaguar Land Rover-trained and Master Technicians, with genuine parts.

Right first time

Correct diagnosis means the right repair, fewer repeat visits, and your Jaguar or Land Rover back on the road sooner.

Air conditioning

Air-conditioning servicing, diagnostics and refrigerant recharging carried out in-house, including the newer gas types used across modern Jaguar and Land Rover hybrid and electric models.

Warning lights

Every warning light deserves a proper look. We read the stored and live data, recreate the conditions where we can, and tell you what is actually wrong before anything is replaced. If the fault is intermittent, we will say so and agree with you how far to go.

Engine management faults

Rough running, misfires, loss of power, poor economy, starting problems and limp-home modes. We test the systems the engine depends on, sensors, fuelling, ignition, air and boost, and identify the cause before any part is replaced.

Electrical faults

Modules, wiring, earths, batteries and charging, comfort and convenience systems, lighting, and the parasitic drains that flatten a battery overnight. Electrical work on a modern Jaguar or Land Rover needs JLR’s wiring data, which comes with being part of the Jaguar Land Rover network.

Software issues

Many faults on current vehicles are resolved by a software update, and many others cannot be diagnosed without one. We check for and apply the latest Jaguar Land Rover software, and carry out the calibrations that some repairs require.

What we diagnose and repair

Drivetrain faults

Gearboxes and transfer boxes, differentials, driveshafts, clutches and four-wheel-drive systems. Noises, vibrations and harshness are investigated methodically, so you only replace what is actually at fault.

Suspension

Air suspension, ride-height and levelling faults, dampers, springs, bushes, arms and bearings, plus the alignment work that should follow. Range Rover air suspension in particular is something owners come to us for.

Emissions, AdBlue and DPF

Where applicable, we diagnose and repair emissions system faults, including AdBlue and selective catalytic reduction, EGR, and diesel particulate filters. These systems are closely tied to software and driving conditions, so we look at the whole picture before quoting.

Mechanical repairs

Engines and timing chains, gearboxes and drivetrain, braking and steering, cooling systems and turbochargers, all handled in-house. From routine replacements through to major work, diagnosed properly and fixed once.

Technical repairs

The work that needs both mechanical and electronic understanding: module replacement and configuration, sensor and actuator faults, high-voltage systems on hybrid and electric models, and ADAS recalibration where a repair requires it.
