Get Fuel and emission control -> AdBlue Guide for Volkswagen Tayron SUV First Generation (2018-2025)

The SCR catalytic converter uses AdBlue urea solution to convert nitrogen oxides into nitrogen and water. AdBlue is a registered

trademark and is also known as AUS32 or DEF (Diesel Exhaust Fluid).

Legal information

No technical modifications should be made to the emission control system that could influence emission control by AdBlue .

Only operation with AdBlue that complies with ISO-22241-1 is approved by Volkswagen and corresponds to the Certificate of

Conformity issued for this vehicle type.

Operating the vehicle without AdBlue that complies with ISO-22241-1 may be a criminal offence.

The emission values may be negatively affected if the emission control system is not operated as intended.

Information on AdBlue

The AdBlue consumption figures depend on the driving style, the operating temperature and the ambient temperature. The remaining

range and refill quantity can be checked on the instrument cluster display .

As AdBlue freezes at -11 °C (+12 °F), refuelling may be restricted at very low temperatures. During vehicle operation, the system is

heated to ensure emission control even at very low temperatures.

During prolonged spells of cold weather with temperatures below -11°C (+12°F), and in extremely adverse conditions, it is possible

that the AdBlue cannot be defrosted and is not available for the emission control system (→ AdBlue).

AdBlue must be refilled independently of the service events. This may be necessary more frequently and between the service

intervals.

The AdBlue tank must never run empty .

Warning and driver inducement system for low tank level

Always add AdBlue when a request to add it appears in the instrument cluster display.

When the white indicator light lights up, AdBlue is still in the normal operating range. It is possible to refill AdBlue , but it is not

necessary.

15 minutes and consult a doctor.

● If AdBlue is swallowed, immediately rinse the mouth out with plenty of water for at least 15 minutes. Do not induce vomiting

unless instructed to do so by a doctor. Seek medical assistance immediately.

NOTICE

If the AdBlue level is too low, the vehicle cannot be restarted after the ignition has been switched off. Starting with jump leads is

also not possible.

● Refill with AdBlue in accordance with the quantity shown on the instrument cluster display at the latest when the remaining

range is around 1,000 km (around 600 miles).

● Never allow the AdBlue tank to run empty.

NOTICE

Improper use of AdBlue may cause damage to the vehicle that is not covered by the warranty.

● Use only AdBlue that complies with the standard ISO 22241-1.

● Never add water, fuel or additives to the AdBlue .

Only use AdBlue that complies with the standard ISO 22241-1.

Filling with a filler nozzle

The AdBlue tank can be refilled at all AdBlue pumps.

Do not fill fuel and AdBlue at the same time.

The AdBlue filler nozzle works in the same way as a filler nozzle for fuel.

1. In order to guarantee optimum refuelling, hold the AdBlue nozzle so that the handle is facing downwards → Fig. 2.

2. Fill with at least the minimum and not more than the maximum refill quantity of AdBlue shown in the instrument cluster

display.

To avoid overfilling the AdBlue tank, do not continue filling after adding the maximum refill quantity of AdBlue → Refilling

AdBlue®.

The AdBlue tank is full when the filler nozzle clicks off for the first time → Refilling AdBlue®.

Filling with a canister

1. Remove the cap from the canister.

2. Use the integrated spout to refill the AdBlue tank.

3. Fill with at least the minimum and not more than the maximum refill quantity of AdBlue shown in the instrument cluster

display.

To avoid overfilling the AdBlue tank, do not continue filling after adding the maximum refill quantity of AdBlue → Refilling

AdBlue®.

Preparing to continue your journey

1. Screw in the tank cap on the AdBlue filler neck until it engages in position → Fig. 1.

2. Close the tank flap.

3. Switch on the ignition for at least 30 seconds so that AdBlue refilling can be detected by the system.

4. Start the engine.

NOTICE

Overfilling AdBlue may damage the tank system and the vehicle.

● Do not fill with more than the maximum refill quantity indicated on the instrument cluster display.

● Remove any spilled AdBlue as quickly as possible with a damp cloth and plenty of cold water.

● Remove any crystallised AdBlue with warm water and a sponge.

repairer.

If the fault is not rectified in the next around 50 km (around 30 miles), the indicator lamps will light up yellow and the remaining

range is around 1,000 km (around 600 miles).

Selective catalytic reduction system fault
