P0410 and P1411 Solved

Thanks for the info. I've been having the same code pop up once in awhile and I have a new one of those. It came with the car lol. I didn't know what it was.
Question: can you point out where it is located?
Thanks in advance

I ended up replacing all the hoses and the reservoir. The hoses looked perfectly fine until you removed them and checked closely at the bend. Ad of course the reservoir crack is so difficult to see unless you put it under high power light and use magnifying glass. Guess you could pressurise it to test as well.

Its kind of buried in the engine which is why I decided not to DIY it (is DIY a verb? I guess it is for me!). What I read is that you can get to it from the top of the engine by removing the passenger side intake manifold or go through the engine service panel behind the seats and remove the alternator.

Of course, there are several other components that can also cause this pair of CEL's like the change over valve or the check valve. Or it could just be a leaking hose/line.

Here is a reference diagram: Porsche Boxster Air Injection Parts

Here is a photo (courtesy of our sponsor) showing the reservoir with the red arrow. The passenger side intake has been removed and the reservoir is behind the alternator.
