Hi,

Dash Ad blue indicator seems to be stuck on 5500 although I filled it over 3 months ago it's never moved.is it an easy fix

?

How many miles ago was that when filled.

The Adblue range might drop 500 miles at a time, and sometimes as the cars / engines gets older it goes many more than 500 miles before dropping.

Is that 5,500 miles the Max Range a Kodiaq shows for AdBlue topped up?

My Alhambra from 2016 showed more and more range as the miles went on, and about 3 year old was just sipping Adblue.

Hi.

ive done about 2000 miles,it really should have dropped.ive heard of overfilling can cause the problem...not that I'm aware I did.going to book it in...just incase it's something else like a blocked injector or something.just thought there may be an easy fix rather than dealer

Not experience from Skoda , but I had an Adblue car for 6 years which had a nominally 17 litre Adblue tank and a tank range of 10000 to 11000 miles, so ~600 miles per litre. I wouldn't expect the Skoda system to be too much different.

I would recommend put in some Ad-Blu cleaner into your systems next time you fill up your car.

I've used Wynn's Crystal Clean & Protect Car AdBlue Preventative Crystallisation Cleaner Additive to keep my system working as well as it can do.

I've had dealings with the AdBlue system on other cars (not the Skoda), and the "sender" in the AdBlue tank only really starts to do anything when you've got about 1200 miles left (2000 km). Any more than that, and the float just sits at the top of its travel. Its only purpose is to count you down to getting locked out from starting the car, rather than working like a fuel gauge. Not sure if that's the same with the Kodiaq - we only ever look at our AdBlue range when it tells us it needs some.

Just keep driving it, it will move eventually!

Hi,

I went down to 1000km left on an Audi Q3 Mk1 TDI150. Never experienced any problem. Since it was a MY2015, it didn't display the AdBlue autonomy, except when only 2000 km left.

I went down to 500km left on my current Superb Mk3 TDI190 (My2017), usually I top up when 1000-1500km left. Never faced a problem with it.

Audi Q3 AdBlue tank is roughly 12l, whereas Superb Mk3's one is around 14l.

Kodiaq one is about 12l. I've been down to less than 200km left.. depends a lot on how much fuel you're using. So when towing, it went through the stuff like there's no tomorrow.

Mine is 14 liters. It starts remind you when there is about 2500 km left.

Beware, AFAIK the engine doesn`t start anymore if the AB level drops to zero.

It won't indeed. It was one of the points my local dealer strongly insisted on, when I took delivery of my Superb Mk3
