In this blog we break down the most commonly displayed Jaguar warning lights, explaining their meaning, potential causes, and recommended actions.
Owning a Jaguar is a luxurious experience, but it comes with its own set of unique challenges. One of the most common anxieties for Jaguar drivers is the sudden appearance of cryptic warning lights on the dashboard. These illuminated symbols can range from mild annoyances to urgent red flags, leaving drivers baffled and unsure of how to proceed.
But don’t worry fellow Jaguar enthusiasts! This blog post is your one-stop guide to deciphering the language of your car’s warning lights. Let’s dive right in.
Jaguar Engine Malfunction Warning Light
The engine malfunction warning light is the most common, and it can indicate a wide range of issues, from minor sensor malfunctions to major engine problems.
Potential Causes: Faulty spark plugs, oxygen sensor issues, clogged catalytic converter, vacuum leaks, etc.
Recommended Action: Don’t panic! While the Check Engine Light might seem ominous, it’s often a sign of a relatively minor issue that can be easily diagnosed and repaired. Schedule an appointment with us as soon as possible to have your car’s diagnostic trouble codes (DTCs) read and the problem addressed.
Anti-Lock Brake System (ABS) Warning Light
A very serious one that should never be ignored is your ABS warning light. The ABS warning light is indicating a problem with the Anti-Lock Brake System (ABS), which could affect your ability to brake safely in an emergency.
Potential Causes: Faulty wheel speed sensors, malfunctioning ABS pump, low brake fluid level, etc.
Recommended Action: Don’t ignore this warning! A faulty ABS can be dangerous to drive. Get your Jaguar towed to a Jaguar mechanic or us, if you can, so we can diagnose and repair the problem.
Jaguar Oil Pressure Warning Light
This is a critical warning light that indicates a drop in oil pressure, which can lead to serious engine damage if not addressed immediately. Costs for a new Jaguar car engine can be magnificently expensive, so it’s best to get booked with us for a vehicle health and diagnostic check.
Potential Causes: Low oil level, clogged oil filter, worn-out engine components, etc.
Recommended Action: Stop the engine immediately and check your oil level. If the oil level is low, add oil carefully (consult your owner’s manual for the correct type and amount of oil). If the light remains on, do not start the engine and have your car towed to us or your nearest qualified mechanic for immediate diagnosis and repair.
Jaguar Coolant Temperature Warning Light
This light indicates that your engine is overheating, which can lead to serious damage if not addressed quickly. More often than not, it could just be that your car engine coolant has dropped below the recommended level and will simply need topping up or replaced. But it could also mean something more sinister.
Potential Causes: Low coolant level, faulty thermostat, blocked radiator, etc.
Recommended Action: Pull over to a safe location and turn off the engine. Allow the engine to cool down for at least 30 minutes before checking the coolant level. If the coolant level is low, add coolant carefully (consult your owner’s manual for the correct type and mixture). If the light remains on, book in with us and get a diagnostic check on your Jaguar.
DPF Warning Light
Modern Jaguar diesel vehicles (ones made in 2019 onwards) will have been built with a diesel particulate filter (DPF), so this warning light applies to all diesel car owners with a make and model 2019 and newer.
Your diesel particulate filter captures and stores exhaust soot which helps to reduce harmful emissions from your car. As with all filters, the DPF has finite capacity and over time it becomes blocked which leads to serious issues for your car.
A clogged DPF filter can cause increased emissions, reduced engine performance, increased fuel consumption and damage to the engine. As well as a failed MOT.
It is illegal to remove your DPF, doing so can result in a fine, and an invalid insurance policy.
