AdBlue range indicator

Post by Mill » Mon Mar 30, 2020 11:25 am

Good day all

Seem to have a problem with the AdBlue range indicator, set off on a journey with the range showing 4500 miles, drove just under 1700 miles (motorways , South of Spain to NE of UK) and it still showed the range as 4500 miles , after around a week later it dropped to 4000 miles. I believe it alters at 500 mile intervals.
Had the car in for its second service and obviously mentioned this, was told on picking up after the service nothing wrong, topped the AdBlue up two days ago, as per handbook, tank took approx 5 lt, still showing 4000 mile range??
Any ideas before i go back to the garage, (if they are open)

My Ateca is petrol but the 2017 Tiguan before was diesel. When given the full top up it showed 6k and would so for over 1000 miles when topped right up. 10l almost always. Sounds like there is a problem. Some Tiguans suffered from the optical sensor that reads the levels being damaged , on the Tig forums this was put down to over filling but VW always filled mine to the very top when they did it.

It may be something like your fuel range, where it goes up and down based on driving style. Motorway driving would have been using minimal adblue as it's just cruising.

There's a warning in the manual about filling it too much - "Filling the AdBlue® tank excessively can cause damage to the tank." The low adbue warning will come on around 1500 miles. Id wait for the warning before topping up to prevent any possible issues of constantly topping up.
