I've only done mine once (about to do again) and added it a litre at a time as I was worried about overfilling. Before I did the last litre I checked what the car was telling me and it said it still needed 1.8 litres but then it nearly spilled over so I was really worried that I'd overfilled it but all was well, I must just have been pouring a bit fast!

Mine needed the first fill. Took it to the Dealer as have the service plan on mine.

What surprised me was it took them 35 minutes to do, and I was offered 5 drinks in the process. All I really wanted was a quick stop and fill and be on my way.

Anyone else found that dealers manage to take a 5 minute job and stretch it out considerably. Not a surprise they charge a fortune for everything.

Yep they do and add to that the time driving to and from the garage, in my case about 40 minutes each way, its just a no brainer, do it yourself.

I bought 10l adblue at Halfords for £12 and topped it up in 3mins.

I suspect they have to plug something in to the car to indicate the level and stop them overfilling, which on some cars leads to problems. The advice on here is clear - never fill to the top (and some tips above on how to make sure you get it right).

No they don’t plug anything in they just fill it up with a miserly amount of adblue. I overfilled mine once and it took days and hundreds of miles for the ultrasonic gauge to start working again. Almost got to the point of taking to the dealer but just got away with it. Mind you I had stuck in about 16 litres! :lol:

I think later cars will say how much is required to top up, and the latest diagnostic system at the dealers does too for all cars.

Collected my new DS on Friday - after driving home i thought i'd check the next service info (at the time with 40 miles on the odometer)..

Next service 19850 (yeah, right !!)

DEF to empty 5468 - no refill required


This morning, now with 106 miles on the odometer, its showing DEF 5095miles to empty.

I can apreciate the car is running in, and it will take some time for things to find a stable position for my typical. usage, but it does appear the DEF level was not full when the car was PDI'd etc.

I won't be going back to the dealer, as it'll cost more in diesel than the DEF itself (which i have on hand), but is there any way to know what the actual amount of DEF there is currently in the tank ?

Assuming 1l/1000miles consumption it might suggest that i need ca 7-8 litres to fill the DEF tank - do you think it's worth adding a couple of litres, check the reading and then add some more (to a total of 5 litres to be safe ?

Or just use the car until it tells me to top up (and hopefully how much to add ?)

I thought later cars told you (in the instrument menu) how much to add - maybe only when it needs topping up?

Quite possibly - this is the latest online manual entry, so perhaps i did have ca 10-12 litres to start with !

HOW OFTEN SHOULD I REFILL MY DEF/ AdBlue®?
The consumption of DEF can vary greatly. An average consumption rate can be 500 miles (800 km) / 1 Litre, but this consumption rate can be more than doubled, depending on the driving style, road and weather conditions.


I'll just let it run down for a few weeks/months and see how it pans out - its only been driven a couple of decent length journeys - once bringing it home (29 miles) and the commute of 20 miles this morning
