If you don't have the correct drive to get the seat bolts out, you can use an 8mm hex key which fits very nicely - especially if it is on a socket wrench. I tried to find replacement M10x1.5 bolts with a button head but no chance at the usual places locally... PKN

The pump ate the foam filter which then destroyed the plastic vanes. Examination of the vanes found them to be quite brittle - either due to age or heat after the valve stuck and pumped exhaust gases through them Steve

Thanks for the tutorial on this. It was not an easy job, mainly because of poor design. Had the valve been mounted closer to the engine room (and it easily could have been) or replaced with an in-line valve rather than one bolted to a metal fitting or even if it had used studs on the valve instead of threaded hole it would have been a 16 minute job instead of a three hour frustrating exercise. Here are a couple of tips if you plan to do this job - glue the gasket onto the pump and find somebody with small hands and a sense of direction to help you, Oh well, it is done now and as expected, the old valve was jammed with teeth from the air injection impeller. While Mr Grumpy is at home, I will also criticize the fact that I cannot buy a plastic $20 impeller which is easily removable. I have to buy the whole motor/pump. Grrrrrrrr PKN

I was surprised that I got this red tailgate picture and warning beep - all it was ...the dog blanket in the back caught in the latch area. It didn't even seem enough to stop the tailgate from closing all of the way but clearly enough to make the sensor think the gate was not shut. A minor latch adjustment might solve your problem. Also check inside the latch area to make sure nothing has dropped through the sprung trapdoor around the latch Steve

Misfires
PKN replied to mbagge01's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)
I spent a long time chasing a similar problem for which my Durametric was of little help. It turned out to be the front O2 sensor which is a bear to change out but relatively inexpensive. If you have over 100,000 miles on the car, I would swap them out anyway Steve -
Does anyone know of a source for the impeller for the smog pumps? It seems a shame to replace a perfectly good pump because the plastic impeller disintegrated, I also need to replace or repait the check valve for bank 2 which is stuck open. Any tips to be had? Steve
-
Its a 2006. The headlight washers certainly work. I just have no sound at all from the windshield washers. I assumed it is a separate pump Steve
-
My guess is that you caused a major vacuum leak when you swapped out the coolant tank. Take a look at the vacuum hoses starting at the air filter and work back. They have a habit of getting brittle and breaking. I changed all of mine out with rubber vacuum hose. I even had to tap and replace the connector at the air filter housing which had broken off. For this I used a brass connector threaded at one end and a barb at the other Steve
-
I tried swapping the fuse. The pump is totally dead with no sound at all. Is this an easy thing to replace or at least check out? Many thanks Steve

I disconnected the plugs and cut the plastic mount off the rear of the housing. reconnected the plug (very tight fit) and wound the light in. Before I did this, the connections would not engage properly and I had all kinds of error codes and light problems. How any engineer could think it is a good idea to use rails to locate a multi pin plug defeats me. I have had no problems at all since making this quick mod... Steve
-
OK - I found the problem. The smog pump on the drivers side had ingested what looks like a foam filter and stripped most of the plastic vanes off the impeller. The vanes then jammed the motor. I am checking to see if the impeller is available separately, if not I will need a replacement pump. I put it back without the impeller for now and cleared down the error code Steve
-
I think I might have a bad connection at one of the two air pumps. The pump is also very noisy when it does run....I can reset the engine light and it is OK for a while then comes on again. Any idea what I should check? Steve
-
I am with Wizard on this. Try attaching a clean separate ground. Also remove plugs and see if she will turn over then Steve
-
Looks like 5 years is as good as it gets with these. I note that later Cayennes used external struts. Has anybody fit a pair of these to a 9PAI model and if so, what was the outcome? If they weren't such a poor design to start with and expensive to boot, I wouldn't be asking Steve

Sure enough it was the driveshaft. I ordered a full unit from Coloradodriveshaft and it got here in just 4 days complete with a return shipping label. It was a breeze to fit taking about an hour each way. Total cost just $350 and it is fully balanced. Great guys and great service. I recommend them. I also recommend buying a four post lift if you don't already have one ! Steve
