Not always. Sometimes, the SCR system needs to be reset by the dealer. Plus, if she wasn't getting the "countdown" message before this, there could be a problem with the system (bad sensor, etc). Probably going to need a visit to the dealer. It should have been warning her 1500 miles ago under normal operation.
This warning is thrown when you reach AdBlue deficiency (0 miles to empty). One the engine has been stopped, it cannot be started until the AdBlue deficiency As a guide, a Volkswagen Tiguan SUV and Passat family car have a 12 and 13-litre AdBlue tank respectively. The rate at which it is consumed depends on the size of the car and the driving style; the more economical the car and driver, the slower it will be used.
Thanks for your answer. I had the 1500 miles warning ( yellow / "please add AdBlue"). I added 3 Gallon. Message disapeared. 200 miles further I got the message (“Refill AdBlue. No restart in 600 miles!) A audi dealer filled the tank ( 23 liters). but message did not disappered. I went home with a red message (“Refill AdBlue.
Sometimes, the reason why your Volkswagen check engine light is on is simply due to a loose or cracked gas cap. This can cause fumes to release in LaGrange, which will signal this warning light for you. Remove your gas cap, and screw it back on tight; if this doesn’t turn off your light, chances are there is a larger issue that needs attention.
Unfortunately at this point the AdBlue counter reset needs to be done with a capable diagnostic scanner. There is unfortunately no other way to get the car started again. After this a exact diagnose needs to be done and checked What exact component on the emission system failed.
