Long story short, buddy with a 996 TT texts me and says his car's thrown the P0491 and P0492 codes.  I found this thread:

P0491 and P0492 secondary air injection codes - 996 Series ...

I read it, pulled the air box, did a visual over the vacuum system, and everything looks ok.  I called another buddy who used to be a Porsche tech and he's saying 7/10 times it's bad BOVs and they need to be replaced.  I could see it if it was one or the other code, but absent a coincidence, when they both throw at the same time, it suggests to me the problem is something that impacts the entire system.

What is the proper starting point to diagnose the SAI system?  Power the pump (also, is the pump located in the driver side of the bumper?)?  Pull the valves and submerge them?

Car has a mystery tune (previous owner) and an Agency Power one-piece CF air box, no other mods that I could tell.  

Thank You in advance.

Thanks! Mine was from the passenger kick panel, so front right for me? I know it's a long shot by any chance you can get a picture of it on a car?

Hey All,

I had a mObridge unit installed at a local shop. It seems the installer got a little too frisky with the car because I found a part of a label on the floor afterward. I got under the passenger kick panel and found the rest. I reassembled it and am now wondering where it goes (yea, I'm that anal about my car). Please let me know if you know where it comes from, and if so, exactly where so I can reattach it.

Thanks in advance,

SVTH

My wastegates went out two days before my warranty ran up, but it was a long weekend and I couldn't get it in until the following tuesday (a day after the warranty ran up). It requires replacing both turbos. Porsche honored the warranty minus $120 for diagnosing. It was strange but I'm not complaining. I think they want to ensure the right stories are getting out about them. They certainly didn't leave me high and dry.

I'm replaced my PilotSports with PilotSport Cups and am burning through them. I'm about to mount my second set since February.

Any recommendations for a tire that can take track abuse but still rack up some mileage?

Update:

My friend/tech confirmed them and their fitment on a 997 TT. the hubs alone are around $5,000 at dealer cost, and then comes the price of new wheels. All of the sudden, my 5 lug looks like heaven.

EDIT: Not GT2, GT3

So I just saw pictures of the new GT2 single nut hubs, very hot. I'm wondering if, in spite of the the turbo's AWD, can turbos have this hub system bolted up? A little too early to tell?

just thinking out loud; can't he hook up a tack adapter to one of the leads for the COPs?

I'm very happy they've decided to use bluetooth. It's always been frustrating to me that my 2005 Dodge truck has it, but not my 2007 TT.

Is the new head unit a direct swap?

I had my iPod input routed through the auxilery 12v inside the armrest, so now there's a big hole with a little wire coming out. Over the months I've lost all sorts of things in there; keys, pens, batteries, whatever.

Can someone assist me in the removal of this console so I can recover my accumulated deposit of belongings?

Thanks,

SVTH

chill with the probing. For the V1 (or similar), use the source for the homelink. put the wire through the back of the clips so as not to cut a single factory wire.

any developments here? Anyone tried this and want to offer a review?

Your dealer got it right, there is a difference in spoiler height between Turbo coupe and Turbo cabriolet (at least on ROW). Unfortunately i have no info, and i cant remember how much difference in mm. it really was.

is this a deliberately engineered difference? I was going to raise mine (coupe) for aesthetics but won't if it messes with aerodynamics/downforce

I just picked up an 07 GT3 as a second owner. The car is great, but there's a stupid rattle/tapping that sounds like it is coming from the front dash, under the chrono clock. It sound like a wire or plastic plug is tapping against something metal.

I've taken it to 2 dealers and none of them can find the problem and do not seem to be willing to take apart the dash (don't really blame them as it may cause more sounds when returned). I've taken out the cup holders, ashtray, AC vent, radio, and AC controls all to find nothing! I've searched and thought it was the AC vent as it seems like a few people had this before. I did find that the door lock switch does shake and rattle a little but this was not it as I've driven the car with the whole thing out.

Any ideas on what could be loose?

Thanks!

pop out the chrono clock and check, directions have been posted here or rennlist or 6 speed.

I ask again, how do I find the aforementioned postings?

Does anybody know how to make the postcat o2 sensors read clean on a 997TT without a retune? Does anyone make MIL eliminators for these cars?

If you've changed the exhaust system you can get CEL's. O2 (bung) extensions are commonly used for this and almost always fix the problem without going to an ECU flash.

thanks for the reply. Does the ECU's perameters have a limit on the lean side or does it only trip a light from the rich side? I guess the question would be, can I simply over extend the bung by about 2" to 3" or is there a "sweet spot"?

I just did a quick google search and I found this was definitely a problem with the 996 PCCBs. Supposedly, but clearly untrue by this post, Porsche addressed the issue to where they satisfy the original claims. I'm guessing this is one of the first cars turning out to prove otherwise.

Good luck figuring it out.

I've never seen a lease outlive a warranty... is this normal or something specific to your situation?

not trying to be rude, but honestly, I think you'll get more useful answers on a sound board, unless you're asking how to retrofit the BOSE system?

are 997 cabs not offered with a hardtop?

It's not broken, it's just an easy way to get a .75" drop while keeping stock ride charateristics

It's either item 9 or 11. There's also one on the bottom pirch not shown in that diagram.

I talked to my tech again today and he said he's seen it done, but the springs creek and are otherwise very noisey without the isolators, although an easy fix for that was to wrap the coil heads with electrical tape. He said he'll pull them off for me so I can try it and see if I'm comfortable with it.

I'll keep the you updated. Thanks Loren.

no ideas?

I'm starting to wonder if it's not a problem with the breaks but more the rubber lines you guys are running. I got a set of 4 SS lines for $70 from pelican parts

Are you talking about the compensation plates?

Maybe... the rubber piece that seats the spring inside the pirch (between the two)

so if I'm understanding this thread correctly, the ceramic (yellow calipers) brake kit is worse for track use?

I have the standard 6 piston Brembos but always thought I was worse off. not true?

um, warranty? and fast.
