Peugeot 308 SW - Peugeot 308 SW Allure 2016 reg- Code P15B3 - ma9gm

Hi,

I had the service light pop up on my 308SW the other day. When I plugged in my reader it gave me the code P15B3. Which I believe means the Additive is low. So I added 10l of Adblue into the adblue tank to fill it up. I then tried to reset the code and it won't go. Does anyone know how to sort out this code? Should it automatically clear itself after filling it up? Or could there be other issues going on?

Appreciate any help or advice.

Very possible that there is a problem with the adblue pump and/ or control module . All part of the adblue tank . About £600 for parts .

Ah, Thank you so much. I had the adblue tank replaced back in July last year. Hopefully it's still under warranty!! I really don't want to pay to replace that!!

Some of these have an Def eolysys tank as well as the adblue tank . Need to check that out . This could be low on fluid .

Oh, I have no idea what a def eolysys tank is. I will have a look to see if mine has it. Are they easy to refill? Or is that a garage thing?

If the Eolys additive tank is running low you should be seeing "Particle filter additive low" or "risk of filter blocking" on the info screen.

But I wouldn't expect it to be low on a 5 year old car, unless you've done lots of fuel fillups of small amounts - an amount of additive is injected into the fuel system every time you fill up.
