Finding a garage that will take a Range Rover booking is easy; finding one that already knows what is likely to be wrong with it is harder. The difference shows up on the bill, so here is what to ask before you hand the keys over.
Why these cars need somebody who knows them
A modern Range Rover or Jaguar is not a difficult car to work on so much as an unforgiving one to guess at. Air suspension, complex electrical architecture, Ingenium and supercharged petrol engines, and a set of faults that repeat across the range in ways an experienced hand recognises in minutes.
A garage seeing its first Discovery of the year will work it out eventually. The cost of eventually is diagnostic hours you pay for.
Six questions worth asking
1. Can you read and code the modules, not just pull codes?
Any garage can plug in a code reader. On a JLR product the useful work is reading live data across modules, running guided tests and, where a component is replaced, configuring it to the car. Ask specifically whether they can code and configure, not just diagnose. A new module fitted and left unconfigured is a car that does not work.
2. What do you do about air suspension?
If a specialist cannot talk fluently about compressors, valve blocks, height sensors and the difference between a leaking strut and a failing compressor, keep looking. On Range Rover and Discovery this is the single most common expensive fault, and the diagnosis decides whether you are spending on one corner or the whole system.
3. Will you use correct-specification parts and tell me what they are?
Ask for part numbers and oil specification on the invoice. This matters for the car, and it matters for your warranty — the conditions in a warranty booklet typically require the manufacturer's schedule and correct-specification parts, which we go through in independent servicing and your warranty.
4. Do you check for outstanding recalls and service actions?
JLR issues technical service actions regularly, and plenty go unperformed on cars that have drifted out of the dealer network. A specialist should be checking, and telling you where the dealer is the right place to go because the work is free.
5. What will you tell me before you start spending my money?
The answer you want is that nothing happens without a conversation. Diagnosis first, findings explained, then a decision.
6. Will you tell me when the dealer is the better option?
Sometimes it is. A recall, a goodwill claim, a warranty repair, or a job needing something only the franchise has. A specialist confident in their own work says so without flinching.
The faults a JLR specialist should already know
Not a diagnosis of your car — a sense of what experience looks like.
- Air suspension on Range Rover, Sport and Discovery — compressors, valve blocks, air springs, height sensors
- Timing chain wear on the earlier 2.2 and some Ingenium diesels, where noise on cold start is the tell
- DPF and EGR problems on diesels doing short urban runs, which describes a lot of Manchester mileage — see EGR valve problems
- Infotainment and module communication faults, where the symptom and the cause are often in different places entirely
- Supercharged V6 and V8 petrols, including their cooling and intake systems
- Evoque-specific issues, which we cover in Range Rover Evoque common problems
A fair word about cost
An independent specialist is usually less expensive than a franchised dealer, and anyone promising a fixed percentage saving before seeing the car is guessing.
The saving that matters is not the hourly rate anyway. It is not paying for diagnostic time while somebody learns the car, and not replacing parts speculatively. A correct diagnosis at a higher hourly rate beats a cheap guess every time.
Where we fit
Mitsiland is in Denton, Manchester, and Land Rover and Jaguar are the two makes we see most.
Our founder, Philip Hedley, is a degree-qualified engineer who worked in research and development at Bentley Motors and at Jaguar Land Rover before setting up here. That background is the reason the diagnostic side of the business works the way it does — these cars were a job long before they were a customer's.
There is more detail in our Land Rover and Range Rover servicing guide and our Jaguar servicing guide, and you can read about the workshop on our about page.
