These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Anybody have one? I checked on Renntech and could not find it. I have a 1999 996 C2

POST 2Original post

Should be easy, no? It's bottom left when you open the rear deck, last I looked there's only a couple of bolts holding it down.

POST 3Original post

Super simple. 1. Remove air box (not really needed, but gives you extra room to work) 2. Unplug tubes and electrical connection 3. Unbolt from car (3 or 4 10mm bolts IIRC)

POST 4Original post

Are you asking how to remove and replace it, or how to take it apart and clean it? Capt. Obvious has covered R/R. Taking it apart is more involved, but I have some pictures if you need them. -Shawn

POST 5 / ORIGINAL POSTEROriginal post

Yes, I would like to see the pics. My indy tells me I need to replace and said I should be able to do it myself. Where's the best source? He was saying the part is like $1200 or some crazy number and recommended I may just want to check my CE codes periodically and learn to love the CE light. I've done that for a few thousand miles and am afraid I may be running rich. I'm due a weekend DIY anyway.

POST 6Original post

I'm fairly confident VW/Audi/Porsche used more or less the same SAI pump for all their cars in this era. When I get home I'll compare them on my cars. If I'm right, you can get a used VW/Audi pump for like $20 on eBay.

POST 7Original post

I have a used one you can have for shipping cost.

POST 8Original post

Anybody ever figure out a sensor bypass method to prevent a CEL after removal? I guess I could just stick it back in there . . .

POST 9Original post

Quotes source post: 9645584

There is no way to prevent a CEL by using a resistor or "bypass" when you remove the SAI. When the ECU triggers the SAI to run, it looks for a lean burn reading from the primary O2s as part of the readiness scan. To get rid of the CEL you need to program out the SAI and/or force a readiness pass (read: you need custom software).

POST 10Original post

Quotes source post: 9645795

or figure out whats causing the cel.... faiulty SAI, carbon blocked piping to exhaust valve, cats, o2 sensor... blah, blah..

POST 11Original post

I didn't have much luck finding an equivalent Audi/VW part, but I'd love to hear about it. I ended up purchasing a used pump off of Ebay for ~$150. Despite several attempts to clean it up I still had the annoying sound on startup. The bearings are "sealed" and must have enough grit in them to have caused damage.

POST 12Original post

Right, but he was asking about how to prevent the CEL if you remove the SAI.

POST 13Original post

Resistor surly or does it constant want a variable reading?

POST 14Original post

Has anybody tried the Bosch OEM replacement secondary air pump: http://www.autoatlanta.com/results.p...605%20104%2000 Mine sounds like a circular saw on start-up, and $470 seems a lot better than $1650...

POST 15Original post

Wow, $500 is crazy for a pump. $1650 is criminally insane.

POST 16 / ORIGINAL POSTEROriginal post

Lon, Thank you so much. Rennlist is AWESOME! Still would like to find a DIY. I,m at weekend shade tree mechanic and it's not the weekend and no shade trees. PS Took the 996 up 176 via the Saluda Grade to Hendersonville and did some hiking with my son. What an awesome drive! I haven't had thrills like that since my last race. I recommend that drive to anyone.

POST 17Original post

Going back a few posts, yes, I removed the SAI pump and would get two recurring CEL error codes because of the vacuum leaks and/or because the "open" electrical circuits and sensors. For entirely different reasons I'm rebuilding my motor now and the builder has blocked off the SAI ports and claims to have "removed" the smog features from the motor (car is a track car anyway). He also claims no more CEL codes because of this. We'll see. Now, I have a SAI pump for sale. Anybody need one--will be much less than $500!

POST 18 / ORIGINAL POSTEROriginal post

I'm still not sure mines not a vacuum leak. This all started when I replaced my starter 6 months ago(DIY). Indy assures me I did it right and connected all hoses but I'm still thinking that's the root cause. We'll see.

POST 19Original post

How can this stupid little thing cost so much? I removed mine recently to replace my coolant tank. It looks like a little fan encased in plastic. Probably cost $5 to manufacture. Some thing I don't mind paying the Porsche tax for but this one is crazy...

POST 20Original post

Quotes source post: 9678795

I had tell-tale signs of SAI switch failure on my 986S last year; fuses were good and I could hear SAI kicking on, but the O2 sensors were showing clear signs it was NOT injecting extra air, and were thus throwing a code. (I picked up a bluetooth OBDII reader and could watch/plot/log the data in real-time on my phone, which was extremely helpful.) I had just had an AOS fail, and was worried all that oil had destroyed something expensive... But ended up I had just knocked the vacuum line off the SAI vacuum reservoir while changing the AOS and hadn't noticed. So little air was leaking that it didn't impact performance, but the pressure loss was enough that the SAI vacuum switch wasn't actuating. Stuck the line back on, good as new!

POST 22Original post

On the top of the engine. If I remember correctly, on the driver, left side, of the engine, under the intake manifold.

POST 23Original post

there is some talk about this on the Renntrack forums http://www.renntrack.com/forums/show...jection-system I thought Krazy had posted a DIY but I don't see it.

POST 24Original post

I removed my pump too. If anyone needs one from a '99, $50.

is the SAI the same on a Carrera as it is on a 996 turbo?
