I cheated. I didn't want to pay the ~$1,000 for an new
Porsche
secondary air pump for my 2009
987.2
, so I searched the Internet for a replacement motor using the information on the motor. No luck, but I did notice there are non-OEM air pumps available for the
987.1
. So, I bought through
Amazon
a
987.1
secondary air pump knock off for about $80. The
987.1
pump has a bolt pattern that is 90 degrees off from the
987.2
so you can't just bolt it in, but I was betting the motors were the same, and I could rebuild mine. (the brushes in my motor were gone.)
Sure enough, motors were effectively identical (but you could tell it was a knock-off). Was able to rebuild my pump with the knock-off motor and so far all is fine.
Yeah, I know, putting a knock-off in a
Porsche
violates the brotherhood, but charging a ~$1,000 for that pump is also against the grain. And even if it dies prematurely, at $80 bucks, you replace them pretty easily before I hit ~$1,000.
Great to hear this.
Next
time you get creative - please bring out the camera and consider doing a little DIY of the job, perhaps with links to suppliers or
Amazon
offering.
FWIW - I'm sure VW didn't tell
Porsche
to make a new pump with a unique design just for our cars. Bet'cha the one that failed on you came from the VW parts bin - but which bin is the question since they own about 15 "brands" now.. On occasion when I was seeking a cross-reference on a part for a
Porsche
, I'd take the old part with me and go visit a VW dealer's parts department. The VW parts guys are likely much more attuned to DIY than the average
Porsche
dealer - it's a different demographic they have as customers. If they're really good - they might look at it and say "Yeah, looks just like the one from a 2007 Fox.."
And again - thanks for your post. A few more details perhaps it might make it into the tech link listing (in the planning stages..)
Hi,
I'm staring down this problem too. I'm getting a check engine light for this on my
987.1
.
How hard is the DIY removal and replace?
Its just under the passenger side (US Spec.), right? Any gotchas, or tips?
Thanks in advance
Caveat: I'm not an expert on the 987.1. It seems to use the same pump, but with a different pump mounting bracket compared to the 987.2,. I believe, the 987.1 uses vacuum to control the injection valve (the 987.2 does not use vacuum, only pump pressure to control the valve). If I am correct, it is critical to make sure those vac lines aren't leaking.
I assume the 987.1 pump is located in same general area as the 987.2 pump, which is on top of the engine block but underneath the plenum and Rt side intake. Anyway, first check the 40A relay in the relay panel.
Otherwise, for me on the 987.2, easiest to remove plenum and Rt side intake (including injectors). Be careful with those brittle vac lines underneath the plenum. Once plenum and intake are out of the way, the SAI pump on the 987.2 is very easy to remove. While you are there. you should also consider replacing the secondary air valve and perhaps the vacuum solenoid (assuming the 987.1 uses vacuum). New intake gaskets and injector O-rings while you are at it.
Lastly, a complete job (but not necessarily at the same time) is to raise the car, remove the exhaust manifolds to expose the exhaust ports and the secondary air injection channels. Chances are these channels and ports (~1/4 inch) are clogged with carbon. You can find some articles on the Net (and maybe here) on how to clean the channels and ports using Carb cleaner, wire brushes and scraper, flexible sink snakes, and compressed air. Nasty job without a lift, but doable. Invest in a face shield.
Don, understood. Thanks. Went with 987.1 pump based off of similarity of images on the Net. Saw a lot of VW pumps, but didn't feel they were similar enough in looks. Motors probably identical, though.
