Push in and rotate counterclockwise to release the blue cap. It was really constrained. I discovered this by physically removing the blue cap assembly and yanking off the black screw cap to reveal it. Removed the black cover, filled container.

Why won’t AdBlue open?
Find the filling cap by opening your hood and adding more AdBlue. Your AdBlue refill bottle’s lid should be removed. When you hear a click, insert the bottle and spin it clockwise.
How can I remove my Audi A5’s AdBlue cap?
Using the box spanner from the Audi A5’s toolbox, unscrew the cap on the filler neck in a counterclockwise direction.
As far as it will allow, tighten the refill bottle onto the filler neck in a clockwise direction (Fig. 2).
Lightly press the refill bottle’s bottom to release the contents. Press the bottle’s bottom repeatedly until it is empty or no longer leaks liquid into the tank.
Turn the box spanner clockwise until you hear the cap click into place on the filler neck.
Driving the Audi A5 is required. The system may not recognize that the AdBlue has been replenished for up to two minutes.
If the AdBlue tank was empty and the instrument cluster display indicated a range of 0 km, turn on the ignition for roughly 15 seconds before starting the engine.
- AdBlue has the potential to irritate the skin, eyes, and respiratory system. If you come in contact with this fluid, wash your hands well with clean water. Ask for medical help if it’s necessary.
- Ensure that any AdBlue you use complies with ISO 22241-1. AdBlue should not be diluted with water or mixed with additives.
- AdBlue should not be applied to the diesel tank because it is not a diesel fuel additive. The engine and the AdBlue tank system may be harmed by mixing AdBlue with diesel fuel. The warranty does not cover this kind of damage.
- AdBlue damages surfaces like painted walls, plastic siding, and carpets. As soon as possible, wipe up spilled liquid with a moist cloth and lots of water. Use warm water and a sponge if the AdBlue has already hardened. AdBlue residues left behind eventually solidify and can harm the surface they are on.
- Refill bottles shouldn’t be kept in the Audi A5 constantly because they could leak AdBlue and harm the interior.
- Don’t let AdBlue touch your clothes. If you come in contact with this fluid, wash your hands well with clean water.
- Any Audi dealer or specialized retailer offers refill bottles.
- Please adhere to the storage and usage guidelines provided by the manufacturer of AdBlue.
How much AdBlue does an Audi A6 consume?
Where is the Adblue-Tank for the Audi A5 located?
Your Audi A5’s Adblue tank filler is located right next to the diesel filler cap in the fuel filler chamber.
- According to the automaker, the 17 Liter capacity of the Adblue tank in your Audi A5 should last for 9.000 kilometers.
- How to refill the Adblue in your Audi A5?
The Audi A5’s fuel filler compartment is placed on the back side. To access it, first lift the flap. The AdBlue tank’s filler cap is located adjacent to the diesel tank’s filler cap. You can either use an AdBlue specific pump for light vehicles or an AdBlue refill kit, which are both sold on Amazon.
How can a stuck def cap be removed?
Have you made sure that the DEF tube’s rubber grommet isn’t preventing the cap from correctly seating? After I pushed the grommet down, the crust on the cap that I had became less noticeable.
I wash the cap with water before replacing it after adding DEF. If the cap is stuck, I would try wrapping a wet rag around the cap and tube and drenching it; if you can get the crust wet, it will disintegrate rather quickly. Just exercise caution while using water near the diesel cap.
Can I restock AdBlue on my own?
Can I top off my AdBlue account myself? Yes, you may refill yourself with AdBlue. Standard AdBlue cans in 5L and 10L sizes are available at every TotalEnergies gas station. Additionally, TotalEnergies is gradually installing unique pumps for light vehicles.
When is the AdBlue tank full, and how can you tell?
The most popular diesel exhaust fluid is AdBlue (DEF). It reduces dangerous exhaust emissions from diesel cars and has automotive urea and deionized water as its main ingredients. As soon as the EU implemented the Euro 6 emissions standard in 2015, it became necessary. AdBlue is as essential to your car as petrol, therefore without it, it cannot function.
When there are approximately 1,500 miles of fuel left in your tank, a dashboard warning light will turn on. This provides you ample time to either buy a container and fill it up yourself, or to bring your car to a motorway service station pump or garage. Your car will enter “limp home” mode and you won’t be able to restart the engine once you turn it off if you ignore the warning light and let your tank get low.
If you decide to top out your AdBlue tank on your own, be careful not to mix it with diesel as this could result in costly damage to your vehicle. Do not start the automobile if you combine the two accidently. Instead, contact your recovery service.
How long is AdBlue usable after being opened?
Examining the expiration date on the bottle, container, or drum is the best way to determine whether Adblue has gone bad. It must be disposed of if it has expired because it is no longer functional. AdBlue may generally be kept in IBCs or tanks for about a year.
Even though Adblue hasn’t passed its expiration date, its quality can gradually begin to deteriorate over time. A change in color, a change in scent, or the appearance of crystals or particles are all indications that Adblue may be spoiled. It is advised to discard the solution right away if you see any of these symptoms.
Which Audi vehicles utilize AdBlue?
AdBlue is used in all of the diesel choices available on several Audi cars, including the A5 Sportback and Q7. The whole lineup also includes the A4 Saloon, A4 Avant, A6 Avant, A7 Sportback, A8, Q3, and Q5.
How can I tell whether my Audi is in need of AdBlue?
Most Audi vehicles will provide you a warning if your AdBlue is low, starting at the last 1500 kilometers. When you use AdBlue, you’ll see that your car runs more efficiently on the road and lasts a lot longer than a regular car.
Am I able to drive without a DEF cap?
Most likely, if you drive a modern vehicle, a small rubber tether secures your gas cap to your vehicle. This way, if you fill up and fail to change it, an indication on your dashboard will alert you. (Or at least you won’t lose your gas cap if your car doesn’t have the indicator light.)
What happens, though, if your car lacks any of these equipment and you accidentally leave the gas cap off while driving down the road? Sure, losing your gas cap is a small inconvenience. You paid for the petrol, so you want it to stay in the gas tank where it belongs. Your fuel system will remain under proper pressure if the fuel tank is sealed off with the gas cap, which will improve your car’s performance. These are the main objectives it accomplishes.
Can driving without one harm your car, then? Most likely not, however there could be some minor problems:
- Due to the filler neck’s role in reducing sloshing, you might lose a little amount of gas, however this will probably be due to evaporation rather than true spills. Any gas loss damages the environment and increases your bills. Not great, but also not a disaster right away.
- Your fuel efficiency may decrease, which again is expensive and polluting.
- Although it wouldn’t be ideal, it’s likely not going to be catastrophic if debris or moisture got into the gas tank because the fuel filter should catch it.
- Performance might be a problem. When the check engine light comes on, some automobiles are set to go into “limp mode,” which lets you keep going at a reduced pace until you can safely stop and diagnose and fix the issue.
- If your state has emissions checks, you must change the gas cap before your automobile will pass. However, there is simply no need to let this persist while you are driving without a gas cap.
In the end, driving without a gas cap has little consequences, and the fix is straightforward. The replacement of gas caps is simple and affordable. The owner’s manual for your car will tell you which cap you need, and you can get a replacement from a nearby auto parts store or internet vendor. Your car dealership’s parts department may also be able to assist.
If you drive off without your gasoline cap, you’ll probably notice it illuminate within a few minutes after you leave the gas station, assuming your car has a check engine light, which the majority of automobiles on the road today do. Even the gasoline cap light is present in certain current vehicles. Don’t worry if either light remains on after you reinstall the gas cap. Before your car’s computer recognizes that everything is well and the light resets, you might need to drive for a whileup to about 100 miles (160 kilometers).
Gas/Fuel Cap FAQ
The engine is not harmed by a cap-less gas tank, nor does it allow fuel to leak out of your vehicle. This is so that gasoline leaks are prevented; flapper valves are typically used in automobiles. The cover, however, serves as a barrier against mud or debris fragments that could harm the engine if it were left open.
The majority of petrol caps are universal and will fit in any SUV or automobile. However, there can be certain exceptions. Fuel caps typically measure 5557 mm in diameter or 5860 mm when the threads are included.
The gas cap is probably not fitting properly if it remains loose or if you smell fuel coming from your car. A malfunctioning (or missing) gas cap is another indicator that something is wrong when the “check engine” light illuminates.
They typically last for 50,000 miles, but if they sustain damage, they could need to be replaced sooner.
