Secondary air pump

[corsa79]

Hi how is everyone? I have an my06 xt forester manufactured late 05 I had a quick search and couldn't see any posts.
I have just started to get faults with the secondary air pump. From what I have read its only emission stuff on start up and its cheaper to pull it out blank off and get turned off in ecu as it continues being a problem once it starts. Has anyone else had problems with this. How have you fixed it and anyone else know who can turn it off in Brisbane without getting a full tune? (as I want to put turbo back exhaust on it before tunning)

Hmmm - seems no one knows unfortunately!

You will need to sell both your legs and a kidney to replace the air pumps with new ones. At the back of each head there is a pipe coming out. It goes to a central point on top of the block. From there it joins up with other plumbing and the air pumps. If you cut each of the pipes a few inches from the head, the stub still connected to the heads needs to be squashed flat and welded shut. As for the ecu side of things, I am not sure. Maybe contact the Queensland wrx club. I don’t think you need a re-tune although you probably need to turn off the alarm in the ecu but best confirm with someone else

There are a few videos by MRT on this topic and a new one came up a couple of days ago that I just happened to watch earlier today. It's made quite clear that deletion of the two pipes, valve and the pump is relatively straight forward (and blanking plates installed on each of the heads, but the ECU does need to be re-programmed to ignore the pump from then on. Brett goes on to say that the ECU is programmable on turbo models and not on NA models, however (bar a couple of cases).

As soon as I got my Forester I thought to myself, "That's something that needs removing as soon as it fails - electric motor and water/mud won't work well".

HI all sorry I haven't updated this. I have pulled all the piping and secondary air pump out and left the one valve electrically connected that had the barometric pressure sensor in. I got a tatric cable of ebay and have turned off the codes related to the secoundary air pump in ecu (found out how from youtube).
Have had this done for the last year no problems also have a three inch turbo back exhaust on. Will get a proper tune one day. Car now has 29000km and its only issue now is a weep from power steering and uses a little bit of oil. I only recently found out of well it does in the sand with a trip up the inland track to camp and back down the beach on Bribie Island.
