Hi All,

I recently had the AdBlue pump fail in my 2015 SQ5. Not a great experience and fairly costly. I had extended warranty (after market) on my car which covers the fuel pump but not the AdBlue pump so they rejected my claim.

When I did a bit of reading it looks like the AdBlue system is part of the overall fuel system so calling by definition the AdBlue is a pump in the fuel system so by definition a fuel pump. That's my logic anyway.

I wanted to see if others had thoughts on this and if I'm being rational or if I have got it all wrong?

Thanks

Sonny

From a quick Google, I would conclude that the Adblue pump and system is not part of the fuel system. Its completely separate and not mixed with your fuel.

Adblue is part of the exhaust system - watch this video that explains how it works.

Probably not what you wanted to hear
I also have a 2015 SQ5, but luckily for me, mine doesn't have Adblue.
