Hey 

Long post alert!!

I have a 06 Impreza with a problem with the secondary air intake pump. I owned the car for 3 months before the engine management light came on. I had a diagnostic done & it shows a problem with the pump. I Initially took my car to a Subaru dealer who ran a diagnostic & said that I needed the pump replacing. After further investigation they said that the pump was working so they replaced a relay which didn't solve the problem. 

It's important to say at this stage that I have a de-cat exhaust & the car has had a full stage 1 remap.

I then decided to take my car to a different local place which specializes in tuning & performance. They said that the pump wasn't working so they have removed everything to do with the pump & I had asked them if they could blank out the pump within the ecu. They are not Subaru specialists & said that I may need a remap to do this & they would investigate things further with another company. 

I thought I would ask on here to see if anybody had the same problem & how it was dealt with.

Thanks in advance 

 

Common problem with this, the air pump is only used for start up to control emissions, so the 2nd place you took it to were right, you'll have to blank off the valves and get a map tweak

I had the same problem,I changed the pump and 18 months later the light came back on, I took the car back to where it was fitted and they checked the pump over and said the pump was OK. So I got it mapped out £60 .I didn't take out the old pump or any pipe work so if you look under the bonnet it still looks standard

OK thanks guys. Looks like I'll look to get it mapped out
