Congratulations on selecting an Audi vehicle with the new TDI clean diesel engine. To get the most from your Audi, you’ll need to know a few things about AdBlue and the TDI emission system. Audi’s ultra-low emission system is an advanced technology for the after-treatment of exhaust gases. In this final stage of treating the exhaust gas, the TDI system introduces a reducing agent known as AdBlue into the gas flow. In the hot gases, AdBlue turns into ammonia which splits nitrogen oxide into non-toxic molecules of Nitrogen and Oxygen — both of which are abundant in the atmosphere. AdBlue tanks must be topped-off by authorized Audi personnel only, so ensure you visit the professionals at Audi North Dublin or Audi Limerick .
Always pay proper attention to the warning system should you be notified of low AdBlue fluid levels.The AdBlue supply needs to be replenished approximately once every 10,000 miles, depending on your driving style and conditions, beginning with the 15,000-mile scheduled maintenance interval. There is a special warning system in place to ensure normal operation of your vehicle at all times. Should your vehicle require additional AdBlue, your instrument panel will begin warning you with sound and detailed instructions when 1,500 miles, 600 miles and limited miles remain. Here’s how the warning system works.
You will be informed if the AdBlue in the tank drops below a certain level. A warning appears in the instrument cluster display when there is only enough AdBlue left to drive 1,500 miles. You will hear a warning signal and the display will show: “Please add AdBlue.”
This is your signal to get your vehicle to your Audi dealer as soon as possible. Your local Audi dealer is trained in the servicing of the TDI AdBlue system and will use the proper refilling equipment and procedures to ensure both your AdBlue tanks are completely refilled.
A warning appears in the instrument cluster display when there is only enough AdBlue left to drive 600 miles (see below). You will hear a warning signal and the display will show: “Refill AdBlue. No restart in 600 miles!”
Be advised: If you drive more than 600 miles after this warning appears without adding AdBlue, the engine will not restart once you stop it. Proceed to either Audi North Dublin or Audi Limerick as soon as possible to have your AdBlue tanks properly and completely refilled.
A warning appears in the instrument cluster display when the AdBlue tank is empty. You will hear three warning signals in a row and the display will show “Refill AdBlue. No restart!” At this point, you will need to add AdBlue or the engine will not restart once you stop it
WARNING • Adding AdBlue on your own will not fully refill the two AdBlue tanks. Adding two refill bottles as described below will only allow you to restart your vehicle and drive directly to your Audi dealer, where your AdBlue tanks can be properly and completely refilled. • Failure to heed AdBlue refill information in the instrument cluster can prevent the vehicle from being started and driven. If the vehicle cannot be driven and an emergency arises, personal injury can occur.
Adding AdBlue (In the event of an emergency)
Filling the AdBlue tank (In the event of an emergency)
IMPORTANT • The AdBlue refill bottle holds approximately 0.5 gallon. Always add two bottles of AdBlue (1 gallon) as soon as a message appears in the instrument cluster display. • The system may take up to two minutes to detect when AdBlue is added. • You can obtain AdBlue refill bottles from any authorized Audi dealer. • Follow the AdBlue manufacturer’s instructions for usage and storage.*
