What solution do you recommend? I am very interested in this too.

I am doing minor cosmetic repairs (reattach liner in the wheel wells, that came loose in places) to my 2007 and was wondering if you can recommend body/trim clips. Ebay has lots of no-name kits, but will those fit the 911? Any advice is greatly appreciated.

Hello, 2007 997.1 C4S here, Arizona daily driver with ~80,000 miles. Took it for a few autocross and track days a 6-7 years ago, but not much recently, other than I enjoy spirited street driving and cornering. When should I replace the shocks? I assume they get tired with age and miles. By the way, the two hood and one engine compartment lid hydraulic supports gave out within a year of each other. I realize the suspension shock are different, nonetheless I was just wondering if there is a natural life to them? I would be looking for Bilstein B4's (I have PASM), but was wondering what is the difference between the B4 and the B6? Many thanks.

Late spring, the AC was running weak, and I thought that with an 11-year old car it's par for the course, so I refilled it a few weeks ago. Did not check for leaks then. The AC is running well now and am wondering if it is going to last. I like your idea of cleaning it all up and monitor -- so that's what I am going to do next.

Thanks @wizard. I did find that the engine compartment temp sensor is loose. Can't find where it attaches, so it is possible the grommet or rubber sleeve within which it sits is lost now. Will get one from a dealer. More concerning, as I inspected the engine, I noticed signs of a leak. My AOS was replace a few months ago, and then I don't remember seeing these leaks. The body of the power steering tank is wet and there seems to be some liquid pooling on top of the compressor below it. Further the lines shown in the photos also seem to leak (AC lines??). what do you make of this? Thanks

After driving 20-30 minutes in warm (100-110F) weather, I have a “failure of compartment blower” error with a flashing light in the top end of the water thermometer. There is no additional specific error code. Oil temp is 200-210, water is 175F. When I stop and turn the engine off the blower is running and keeps running for another 20-30 minutes. This is a 2007 997.1 C4S, bone stock, 72,000 miles, runs well, water pump and thermostat replaced preventively at 60K by dealer. Any advice on how to handle this? Is this a sensor problem?

Yup, it was the AOS. Hat tip to you, gentlemen. Sent from my Pixel XL using Tapatalk

Thank you both you guys are great! Will post an update for the archives once sorted out. Sent from my Pixel XL using Tapatalk

My bone-stock 2007 997.1 C4S with 71k miles is my daily driver, and the last few days it has a big puff of blueish smoke upon engine startup which then clears in a few seconds. The smoke occurs in the morning (cold start) and also on warm restart. I searched on Google and found that these engines can burn a little oil etc, but strangely enough it hasn't done this for 11 years and 70k miles, so I am thinking something is wrong. Coolant is not low. Car maintained at the dealership, except for oil changes which I do myself every 5000 miles. Also has P2187/2189, which it had before and I cleared it with Durametric thinking it's the gas cap. Maybe I am imagining it but the exhaust is a little more hoary than before. Any ideas? Thanks guys.

Ok, just for the archives, it was a faulty MAF sensor. Thanks JFP. Sent from my Pixel XL using Tapatalk

Is there a way to check with the Durametric if the MAF works?

CEL went off over the weekend, Durametric showed a P2190 code. Car is a 2007 C4S coupe w/ Tip at 69,000 miles. Basically bone stock, serviced at the dealer. After checking with Durametric I opened the hood and noticed that the hose clamp connecting the wide Y hose from the airbox onto the intake manifold came loose. So I though there is a vacuum leak, took off the airbox, replaced the airfilter, cleaned the MAF. noticed a few ml of oil-like fluid inside the throttle body just at the level of the butterfly flap; so I cleaned that up. Tightened oil fill and gas caps. Reconnected everything, cleared the code but now it came back a day later. I have an appointment with the dealer in a few days. Any suggestions what I can do to maybe fix this on my own? Many thanks

I had that problem and dealer diagnosed a faulty PASM ECU, replaced it and it solved the fault. Sent from my Pixel XL using Tapatalk

Dealer said a rubber sleeve leading to the intake came loose. They tightened it and that resolved the problem.

Thank you Ahsai for your helpful replies, I will drop it off at the dealer today and see what they find.

RKAT is stable at 6.984 for both banks. Just noticed that when in D and stopped, and want to get rolling and just feather the gas it sounds loud and rough (like a 1980's diesel) until the revs reach ~1,100, then it quiets down.

Before this happened, the idle in P was around 750-800. This behavior (P idle ~1,110) is new, and, I believe, abnormal.

2007 C4S with Tip and 58,000 miles My CEL came on yesterday, due to codes 2187/2189. After a brief search on the internet, loose oil/gas caps came up as possible causes. So I cleared the codes and tightened the caps, but the CEL came back a few hours later. I also just noticed last night that, when idling in Park, it revs at ~1,100. In Drive with the break on and the car not moving (no pressure on the gas pedal) the idle revs drop to normal (around 700-800). Also the idle is a little rough. Any ideas what causes this? Thank you all.

Agree they need to match (have MPSS on all four currently), but they wear at different rates. I drive about 12,000 mi per year, do one or two DE days per year (with the street tires), so I replace the rears more frequently than the fronts. Now, for the first time I will be forced to use Pirellis but don't want to replace all four as I don't want to waste the fronts that still have half the thread. Which non Michelin tires come close to the MPSS?

I need to replace the rear tires on my 2007 C4s and it turns out the Michelin Pilot Super Sports are completely unavailable, with no ETA. Even if one makes allowance for the odd size and likely small demand, that is still pretty shocking. What alternative have you tried and what do you recommend? Car is a daily driver, street driven, I value quiet running (not that our cars are *that* quite, but would rather not add running noise).

If the car has a tiptronic, is the process any different? Thanks.

Thank you for the clear description. Is the process you detail for a manual or a tip? What is the difference if the car has a tiptronic and is the replacement still doable at home?

Porsche is part of VAG, the Volkswagen group. Why does that matter?
