After 16k miles the car was saying 2000 miles adblue range.  Simples I thought, just pour some in before we go to France.

 

Except it didn't register. 

 

Realised when the 600 mile warning came up on the way home that (1) I had added a couple of litres and it was expecting a couple of gallons and (2) that the car needs to sit for up to 30 seconds with the ignition on without starting the engine to register what has been added.

 

1.5 gallons added and registered by the system.

 

Al least I didn't do what my father appears to have done  - adblue in the diesel tank.  He swears he didn't but no one else would have put adblue in his car.

@IJWS15 Have you had the car from new and that is the first topping up with AdBlue or was it added before at a service when in a Dealers?

Had it from new and first top up, first service was 3 1/2 weeks ago and the dealer didn't put any in.

Reading an old thread i see that some mention that the manual said up to 18,000 miles and yours must really  be capable of that then.

Others posted getting no place near that. 

 

?

So what range does it show now for the AdBlue.

 

My 2016 2.0TDI DSG Alhambra came to me with a 7,000 mile range, and at the first top up that that was 7,500 miles, then 8,000 miles at the next and then it started just sipping the AdBlue and the DPF was clogging.

adblue tanks vary in size on all the skoda models, the superb has a large tank so range likely to be greater.

they dont like being overfilled so you need to be careful and i believe adblue has a shelf life as well,  imo adblue systems are more problematic than dpf and egr valves.

there is too much to go wrong and it often does go wrong, pump, nox sensors, warning light on that will fail an mot .

However, if keeping the car after the 3 year warranty is up,  there's  an easy fix which ensures no more adblue problems  😇

 

@310golfr You do get different AdBlue tank sizes with different models.

The Alhambra had a 63 litres diesel tank and a 17 litre AdBlue tank but had a Euro 6 Engine.

 

I do not think the Superb's Adblue tank is any bigger than 17 litres but i might be wrong.

The AdBlue self life stored in ideal conditions at 18 months or whatever is pretty OK in the UK and in the car.

It is out of direct sunlight in the vehicle, but it might go below -6*oC occasionally & above 25*oC.

It might get used up in 18 months in cars doing 12,000 miles a year.

 

But then the AdBlue was manufactured & transported and stored before it ever got into a vehicle.

Maybe even 10 or 20 litre containers sitting outside a Filling Station Shop in sales lockers, the cover open & in direct Direct Sunlight at BP Filling stations and the likes.

That is when it was plentiful and there is not a bit of a shortage like now. 

 

** Cars sat Bunkered for months when the WLTP came in and they have AdBlue in the Tank from the factory,

cars have sat unfinished from the production line now and are still sitting, that is Oil, Brake fluid, Haldex / DSG oil, some limited amount of petrol or Diesel and Adblue all maybe a year old before the car goes on the road.**

This figures looks really high 😮!

I usually wait until 1000 or 500km AdBlue range left before filling up and once fully refilled (around 10-11l), it generally displays 14000km range...

I assume the AdBlue tank has the same capacity whatever TDI150 or TDI190.

Skoda really managed to sort out engine management & emissions and the low usage of Adblue / SCR if the tank is less than 17 litres and can do 18,000 miles.

If they had done that years before for TDI's in the USA they would have saved Billions in penalties because of being caught having introduced defeat devices. 

I think VW were done over the emissions case in the US, after all the legislators said we will measure on this cycle and that is what the public see, VW did what they were asked to do.  If you drive the car differently you get different results.  My driving style must put  the car into the test cycle settings since I once got 84mpg out of a 2.0 Tdi Passat and this car will do over 70mpg.   If the cars they delivered to customers wouldn't achieve the test figures then there was a case but my experience is that they will.

 

The Adblue started at 11k miles when it was new and stayed at that figure for a long time,  don't recall it being higher but I didn't look very often.  I haven't been commuting much so it has been mainly sdp use, probably 80-85% long runs to visit family and the occasional trip to head office.  Car didn't sit around new, it was a factory order and manufacture was delayed by the factory shut down in 2020 - was originally due April 2020 and arrived September.  It was reporting adblue range of 7000 miles last week.

They (the law makers in the US) also said that defeat devices (those that switch off emission control equipment for no good reason) are illegal. In very clear legalese that VW couldn't wriggle out of like they could in the EU where the regs weren't so clear cut.

I topped up yesterday. The range said 1900 miles left, I topped up 10 litres and the range said 8000 miles so I presume I'll get 6100 miles there or thereabouts from 10 litres.

@IJWS15The TDI's could achieve the economy.   

They could not achieve the low emissions though while achieving the figures.

 

When Kia / Hyundai were caught out not achieving the economy they claimed in North America and Canada they were penalised and had to give fuel cards to cars owners. 

They were fined 100 million dollars in the US in 2014. Ford had to reimburse 215,000 customers for exagerating fuel economy.

I've done around 20 thousand kms in my car since i bought it and I've had to refill Adblue twice now, both times with 10l and increasing range by around 8-9000kms. €30 for the last canister. Still had 3000 range left last time and it said I could add 11l. 

Will have to look at how clogged my DPF is.
