A complete Jaguar warning lights list - from engine management to transmission and suspension. Whether you have a yellow engine light, an amber glow plug, or a red restricted performance warning, this index helps you identify the light, understand the urgency, and find the right next step.
Jaguar warning lights are grouped by colour: red means stop now, amber means schedule inspection, green/blue mean system active. This index covers every dashboard light reported on Jaguar forums and specialist dashboards, with direct links to the detailed pages for the most common symbols.
Use this Jaguar warning lights index to find the warning light you've seen, understand what it means for your model, and get to the specialist help page you need.
Red warning lights are the most urgent. They indicate a critical fault - low oil pressure, overheating, or a brake system failure. If you see a red light, pull over safely and stop the engine as soon as it is safe to do so.
| Light | What It Means | Action | Guide |
|---|---|---|---|
| 🚨 Oil pressure | Engine oil pressure has dropped to a dangerous level | Stop immediately - engine damage occurs within seconds | Oil pressure warning |
| 🌡️ Coolant temperature | Engine is overheating; may indicate coolant loss or a seized thermostat | Stop; let engine cool; check coolant level | Coolant temp warning |
| ⚠️ Battery / charging | Battery not charging; alternator or battery failure | Stop if power steering fails; call for recovery | Battery warning |
| 🔴 Transmission fault | Gearbox fault detected - loss of drive possible | Stop; do not continue driving | Transmission fault |
Red lights on a Jaguar are always urgent. Restricted performance can accompany a red light - it's the car's way of protecting the engine. Our vetted specialists can diagnose red-light faults via diagnostic kit without needing to drive the car.
Amber warning lights are the most common Jaguar warning lights. They mean a fault has been logged but the car is generally still drivable - though ignoring them can turn a £200 repair into a £5,000 engine replacement.
| Light | What It Means | Common Causes | Guide |
|---|---|---|---|
| ⚠️ Engine management light (EML) | ECU has logged a fault - may be emissions, sensor, or timing-related | O2 sensor, DPF, EGR, MAF, injector, timing chain | Engine management light |
| 🚫 Restricted performance | Car has reduced power to protect the engine - often throttle or turbo related | Turbo actuator, fuel pressure, DPF | Restricted performance |
| ⏳ Glow plug / pre-heat | Glow plugs are faulty or the control module has failed | Faulty glow plug, wiring, ECU communication | Glow plug light |
| 🧹 DPF warning | Diesel particulate filter is blocked or regeneration has failed | Urban driving, EGR failure, faulty differential pressure sensor | DPF warning light |
| 💧 AdBlue warning | AdBlue level low, system fault, or NOx sensor failure | Low AdBlue, NOx sensors, heater, pump | AdBlue warning |
| 🔄 Suspension fault | Air suspension or electronic damper fault | Compressor, valve block, height sensor, leak | Suspension fault warning |
If you have an amber engine management light on a Jaguar XF, XE, F‑Pace or XJ, check the corresponding fault code or use our diagnostic wizard to narrow down the cause. Many amber lights are fixed with a sensor or DPF clean, but Ingenium diesel timing chain faults also show as an amber EML before they become catastrophic.
Green and blue lights on a Jaguar dashboard indicate that a system is turned on and operating normally. They are not faults but can appear alongside an amber or red light if there is an underlying issue.
Green lights do not require action. However, if you have a green light and an amber warning together - for example, a green Eco light and an amber DPF light - the Eco system may be preventing a DPF regeneration, which can worsen the fault. Our DPF emissions guide explains the link.
Jaguar warning lights list is a reference; what you do next depends on the colour and the car's behaviour.
If the light is red, stop the car as soon as it is safe. Turn the engine off. Do not restart. Call a specialist or recovery. Oil pressure warning and coolant temperature are the two most urgent.
Amber lights - engine management, DPF, AdBlue, suspension - need diagnosing. Use our diagnostic wizard or check the relevant fault code page. Some faults can be driven for a short time; others need immediate attention.
A flashing engine management light means an active misfire. This can damage the catalytic converter. Pull over and turn off the engine. Misfire rough idle is the most common cause.
Green and blue lights are normal. If they appear alongside an amber warning, check the amber light first. Do not ignore an amber light because the green light makes it look "normal".

The amber engine management light means the ECU has detected a fault, typically emissions-related (O2 sensor, DPF, EGR) or a timing/chain issue. It requires diagnostic scanning. Full EML guide.
Restricted performance is a limp mode to protect the engine. You can drive a short distance to a garage or home, but not at motorway speeds. Restricted performance guide.
AdBlue warnings can be due to low fluid, a faulty NOx sensor, a failed heater, or a pump issue. AdBlue warning page covers all causes and costs.
Air suspension faults are usually a compressor, valve block, height sensor or an air leak. Suspension fault warning explains diagnosis and repair costs.
The glow plug light can mean a faulty glow plug, a control module failure, or a wiring issue. It often appears alongside the EML. Glow plug light page.
Yes - this page is the complete Jaguar warning lights index. Each red, amber and green light is listed and linked to a detailed guide. If a warning light is not listed, use the diagnostic wizard to identify it.
