DPF additive warning

[Cupra to DS5]

Hi all
I've had the DPF additive fluid low warning come up on my dashboard and am just trying to verify that it's the tank I have rather than the bag

I've got a 2013 DS5 2.0 Hdi Sport

It's in for a service next week but the garage asked me to double check

Thanks

You have a reservoir, not a pouch system.

Hi Marc
I thought so but knew you'd know for definite!
Thanks for the reply
Cheers

Hi guys does anyone know of the 2017 DS5 has this additive?

[GiveMeABreak]

Of course. All DS5 Diesels have a DPF system and therefore have a DPF additive used with it. Being a 2017 model, your DS5 will almost certainly have in addition to the DPF system, an SCR (Selective Catalytic Reduction) system to treat NOx. So you will have separately, and in addition to, an Adblue tank for this purpose.

The filler access for the Adblue will be under the boot floor on the rear left hand side if you have the Blue HDi engine, shown here:

Thanks Marc.
Yes I was told by the seller about the ad blue tank

How do you fill it is that the filling cap on passenger side carpet has a flap with a green cap under it

@mkjohns2012: Unlikely in your case, as yours is a 2013 model, based on the vehicle in your profile. If this is the case it's too early to have a SCR system fitted, but your VIN will confirm.

Vfkfrhhacs528165 is it easy to refill or is it best at a garage..thanks

@mkjohns2012:

You have a 2012 (Dec. 2012) build so too early for the SCR (Adblue) system to be fitted, so ignore the diagram above.

Back to the Additive for the Particle Filter, the tank is gravity filled and is located hidden under a heat shield next to the fuel tank. You will need Powerflex additive to fill the reservoir, and do not have a pouch-based system. Don't forget you will need Lexia / Diagbox or similar to reset the additive counter int he engine ECU after topping it up (minimum of 1 litre).

How meny Litres dose the tank hold do you know
Thank you so much for your help

[mkjohns2012]

The warning has just popped up today how long do you have to get it refilled Thanks

1) The additive tank has no physical measurement - the volume is estimated and a calculated value based on when the tank was filled and the amount injected over time. I suggest therefore you purchase 2 x 1 litre containers, put a minimum of 1 litre in, and then try the second. Some tanks are 3 litres and some are less - I can't advise as the tank volume isn't specified in parts.

2) Regarding the warning and distance remaining:
The engine ECU looks at your service / maintenance counter reading to see how many miles are remaining until your next scheduled service. It then calculates if the estimated additive remaining in the tank is enough until your next service. If there is not enough fluid until the next service, it will flag the warning up. So the distance will be less that what the mileage showing until your next service is.

Never seen any evidence to support point 2 - far as I know it just comes on at a preset volume. It invariably comes on after a fuel up, if 2 was the case then it should come on immediately the service indicator is reset. My Sister's car was (very...) overdue a service when the warning came up.

Yes, it's documented Richard.
