Hey everyone,
My DS7 recently popped up the service light, and after checking the DTC, it says the additive tank is empty. Can anyone help me figure out which type of DPF additive I need to buy to refill it?
Unfortunately, I don’t have access to the PSA Service Box in my country.
Here’s my VIN in case it helps: VR1**************[VIN obfuscated, can be read by forum staff]
Thanks a lot in advance!

My access is currently unavailable though there may be a member with access to help you out, in the meantime a call to your dealer should get you the information. 
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

Hello,
You probably figure this one out but for others needed, aditive is powerflex 3 Blue cap..I refill few weeks ago and used Walker PowerFlex 3.
Tank can fit 1.2L but adding 1L is ok. After refill since aditive tank doesn't have level gage, you need to use diagnostic to tell that tank has been refilled. After than clear error and you should be fine.
