Why is the AdBlue light still on after filling Audi a4?
When the AdBlue warning light remains after refilling, the system may need a reset or sensor check. The AdBlue tank level sensor or dosing unit could be faulty or clogged. After filling, drive the vehicle to allow the system to recalibrate. Adblue is not physically required to run an engine, but running an engine without it will cause the vehicle emissions to exceed what’s legally permitted, so the vehicles are programmed to refuse to start if it runs out. Some will restrict performance if the adblue runs low, again to reduce emissions.If you do not have an anti-spill nozzle to hand, remove the AdBlue® tank cap and place a funnel in the top of the reservoir. Slowly refill the AdBlue® tank until it is full. Some vehicles require a dashboard reset after a top-up to remove the AdBlue® warning light.Technically, a diesel engine can still operate if it runs out of AdBlue; however, in practice, most modern diesels are designed to prevent this. When AdBlue is low or absent, engine performance is often restricted to “limp mode,” limiting speed and power to encourage refilling.How do I start my car after running out of AdBlue? If you’ve completely run out of AdBlue, your car won’t start again until you’ve refilled typically around 3-5 litres. Once your car starts, the AdBlue warning light may take some time to catch up.
