Why a Range Rover isn't just any car for a workshop

Air suspension, more than 40 interlinked control units, complex diesel V6 emissions systems and a ZF 8-speed automatic gearbox — a Range Rover packs almost everything that can go wrong on a modern vehicle into one car. The good news: most of its typical faults are well identified, and fixing them in time costs far less than waiting for them to get worse.

Here are the 7 faults we see most in Range Rovers in Valencia, how we actually diagnose them, and their indicative price.

1. Air suspension (EAS) "sagging" or the car sitting crooked

It's the most typical symptom: the car wakes up low on one corner, one side, or all four. The cause is almost never "you need a whole new compressor" — usually it's the air springs (front or rear) leaking through the rubber, a valve block that isn't sealing, or a tired compressor that can't build pressure any more.

Real diagnosis: we measure pressure at each corner and run a leak test before touching anything. Indicative price: inspection and leak location ~€60–90; replacing one air spring ~€350–550; full compressor ~€450–700.

2. Loss of power and smoke — dirty EGR and turbo

On TDV6 diesel engines, this is the most common fault from around 120,000 km: the EGR valve clogs with soot, the turbo develops play and the intercooler gets blocked. The car loses power, smokes, and sometimes goes into limp mode.

Before fitting expensive parts, we try a specific EGR and intercooler clean. Indicative price: EGR cleaning ~€180–280; turbo inspection or replacement depending on the case, ~€700–1,400.

3. Jerking or "not engaging" in the ZF 8HP gearbox

The ZF 8-speed automatic is reliable if properly maintained — the problem is usually dirty mechatronics from aged fluid, not the gearbox itself. Before considering a full gearbox replacement (€3,000–5,000 at the dealer), we try an oil and filter change with the correct JLR procedure.

Indicative price: oil + filter change with the specific procedure ~€250–350; mechatronics repair if needed, ~€900–1,600.

4. Dashboard warning lights with no obvious cause

Range Rover multiplexes almost everything: BCM, sensors, cameras, comfort modules. A light that comes on and off by itself usually points to one specific sensor or a module with an intermittent fault — not "you need a whole new control unit", which is the first thing some workshops suggest without a real diagnosis.

Real diagnosis: a full read of the vehicle's 40+ ECUs with dedicated JLR equipment. Indicative price: full diagnostic ~€70–120; the repair depends on which module is affected.

5. Metallic rattle on a cold start — a stretched timing chain

Unlike belt-driven engines (see our timing belt guide), the TDV6 uses a chain — but in practice it stretches earlier than the manufacturer promises. If you hear a metallic rattle for the first few seconds after a cold start, don't ignore it: a chain that jumps a tooth can end up bending valves.

Indicative price: chain, tensioner and guides replacement ~€900–1,500 — far less than a new engine.

6. "Restricted Performance" warning — high-pressure fuel pump

If the dashboard shows a "Restricted Performance" warning and the car loses power, especially when cold, suspect the high-pressure diesel pump. We diagnose it by measuring rail pressure and checking for contaminated fuel or water, a frequent cause of this fault.

Indicative price: rail-pressure diagnosis ~€80–120; high-pressure pump replacement ~€600–950.

7. Coolant and oil mixing — the engine's heat exchanger

This is the least well-known fault, and one of the most serious: on TDV6 engines, the heat exchanger (oil cooler) that separates the coolant circuit from the oil circuit can crack with age, mixing both fluids. If the oil looks "whipped" (like milky coffee) or the coolant level drops with no visible leak, this is the first thing to suspect.

What many people don't know

Caught early, replacing the heat exchanger costs considerably less than an engine repair caused by bearing washout from the mixed fluids. That's why on every TDV6 check we look at the oil's appearance on the dipstick — it's let us catch this fault more than once before it turned into something bigger.

Indicative price: diagnosis + heat exchanger replacement ~€450–750.

Range Rover at the dealer vs a specialist workshop

You don't need to go to the official dealer to keep your warranty: the EU Block Exemption Regulation allows servicing at any qualified workshop without voiding it, as long as the intervals and Jaguar Land Rover specifications are respected — which is exactly what we do.

The main difference is labour cost: in Valencia, official JLR dealers typically charge €85–110/hour, versus our €50/hour. On big jobs (gearbox, chain, suspension) that difference can add up to several hundred euros.

How to avoid surprises: diagnosis before you pay

A Range Rover with an unusual symptom can end up with very different quotes depending on the workshop, because not everyone diagnoses properly before pricing. Our rule: first a real diagnostic with dedicated JLR equipment, then a fixed written quote for what needs replacing and which brand, and only then do we start work.

What we do at 2 Hermanos

We're independent Range Rover specialists in Aldaia: JLR diagnostics, component-level air suspension repair, engine repair (chain, EGR, turbo, injectors) and ZF 8HP gearbox maintenance, all backed by a 12-month written warranty and up to 50% less than the official dealer.
