Peugeot 2008 AdBlue Capacity: Complete Guide to Litres, Refill Tips & BlueHDi Requirements

We know how essential it is to keep your Peugeot 2008 running clean, efficient, and fully compliant with emissions regulations. That’s why understanding its AdBlue capacity—and maintaining it correctly—is one of the smartest habits you can develop as an owner. In this complete guide, we break down the exact AdBlue litres for every Peugeot 2008 diesel version, how the system works, when to refill it, and the smartest tips for avoiding costly SCR-related issues. Let’s dive in.

Understanding the Peugeot 2008 AdBlue System

AdBlue plays a key role in the Peugeot 2008’s BlueHDi diesel engines, especially those built to meet Euro 6 emissions standards. By injecting a precise dose of urea solution into the exhaust stream, the system neutralises nitrogen oxides (NOx), turning them into harmless nitrogen and water vapour. It’s the backbone of Peugeot's modern diesel technology, and keeping enough AdBlue in the tank ensures your SUV stays efficient and legal on the road.

Knowing the exact litre capacity of the AdBlue tank is crucial—not only for maintenance but also for planning road trips and preventing unexpected warnings.

Below is the definitive breakdown:

Why some versions vary

A few factors influence tank size:

• Updates in emissions regulations
• Changes in SCR hardware placement
• Variants built for different regions

Even with slight variations, the majority of Peugeot 2008 BlueHDi models fall within the 12–17 litre range.

Peugeot 2008 AdBlue Consumption (Real-World Figures)

Although the tank size tells you how much AdBlue you can store, what really matters is how fast you use it.

Typical consumption ranges

On average, the Peugeot 2008 BlueHDi uses:

• 1.5–2 litres every 1,000 km
• A full 17-litre tank lasts 10,000–15,000 km
• Newer 12-litre tanks last 6,000–9,000 km

What affects consumption?

• Heavy loads
• High-speed motorway driving
• Cold weather
• Frequent stop-start traffic
• Aggressive acceleration

Driving gently and maintaining steady speeds leads to noticeably lower AdBlue use.

How the AdBlue System Works Inside the Peugeot 2008

To understand why refilling matters, let’s walk through the system itself.

Key components

• AdBlue tank: 12–17 litres depending on version
• Heated supply module: prevents freezing
• Precision injector: sprays AdBlue into the exhaust
• SCR catalyst: converts NOx into nitrogen + water
• Sensors: monitor quality, temperature, and tank levels

When the Peugeot 2008 Warns You About Low AdBlue

Your Peugeot 2008 gives multiple alerts before the system locks you out from restarting the car.

Warning stages

Stage 1 – Early warning
A message appears: “AdBlue: Range 2400 km”

Stage 2 – Low level
“AdBlue: Starting prevented in 600 km”

Stage 3 – Critical level
“Starting impossible in 0 km”
At this point, the engine will not start until you refill.

We strongly recommend refilling as soon as you see Stage 1.

How to Refill AdBlue in the Peugeot 2008 (Step-by-Step Guide)

Refilling AdBlue is simple, but doing it incorrectly can damage the SCR system. Here’s the correct procedure.

Step 1 – Locate the AdBlue filler

On the Peugeot 2008, it is:

• Under the boot floor
• Next to the spare wheel compartment
• Marked with a blue cap

Step 2 – Prepare the right AdBlue container

We recommend:

• ISO 22241-certified AdBlue
• A 10-litre bottle with a spill-proof nozzle

Step 3 – Fill slowly

• Insert the nozzle
• Pour steadily to avoid air pockets
• Stop once the system auto-shuts or you reach max capacity

Step 4 – Close securely

Make sure the blue cap clicks. A loose cap will trigger “AdBlue Fault” messages.

Step 5 – Restart the vehicle

The Peugeot 2008 typically recognises the refill after:

• A 30-second ignition cycle
• A short drive

Putting too little may not clear the warning.

Consequences of Driving Without AdBlue

Ignoring an empty AdBlue system leads to several problems:

1. Engine won’t start

Once the countdown reaches zero, your Peugeot 2008 will refuse to restart.

2. Higher emissions

The car cannot legally operate without SCR functioning.

3. Risk of expensive damage

Running with poor AdBlue quality or a bone-dry tank can harm:

• SCR injector
• Catalyst
• Sensors

Repairs easily exceed €800–€2,000.

Common Peugeot 2008 AdBlue Problems and How to Avoid Them

Even with good maintenance, some owners face issues. These are the most frequent ones.

1. AdBlue system fault message

Often caused by:

• Air pockets
• Contaminated AdBlue
• Bad sensors

Solution: refill fully, then restart; if persistent, run diagnostics.

2. Crystallisation around the filler

Occurs when AdBlue spills and dries.

Solution: wipe spills immediately.

3. Frozen AdBlue

AdBlue freezes at –11°C, but Peugeot systems include heaters.

Solution: allow car to warm before worrying—the heater unfreezes it.

BlueHDi Models That Require AdBlue

All diesel Peugeot 2008 models with BlueHDi engines need AdBlue:

• 1.6 BlueHDi 100
• 1.5 BlueHDi 100
• 1.5 BlueHDi 130

Petrol PureTech and electric e-2008 models do not use AdBlue.

Tips to Reduce AdBlue Consumption in the Peugeot 2000

You can make each tank last longer with a few simple habits:

• Maintain steady motorway cruising
• Avoid constant hard acceleration
• Keep tyres at correct pressure
• Remove unnecessary weight
• Avoid idling whenever possible

Small changes genuinely make a difference.

Recommended AdBlue Brands for the Peugeot 2008

To protect the SCR system, we recommend:

• TotalEnergies AdBlue
• Bosch AdBlue
• GreenChem AdBlue
• Yara Air1

Always look for ISO 22241 certification on the label.

Summary: Peugeot 2008 AdBlue Capacity

Here’s the quick recap:

• 2016–2019: 17 litres
• 2020–2021: 16 litres
• Later models: approx. 12 litres
• Consumption: 1.5–2 L per 1,000 km
• Refills typically needed every 10,000–15,000 km
