I bet your right about the sensor being on top of the gas tank. Good luck with all this. With the racing fuel cap and a big tank you will soon be running full out at Thunderhill.
judgejon replied to JFP in PA's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks. I will be taking your good advice. I'm aware of the 6/75k thoughts on the retrofit bearing. I drive a 2003 C4$. I had the retrofit installed in 2011 at about 40k miles on the car. Mileage now about 60k. My plan is to change to the Solution at around 70k miles. Does this fit with the various situations you've seen in the shop? Cheers, jl

judgejon replied to JFP in PA's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Or, if you do as provenance, keep your repair record from the shop that did the work. This is probably ok if the shop is licensed by your state, like CA through the BAR. And as a related digression, Jeff, I have about 25k the retrofit on my 2003 C4$. I'll be getting another put in after about 10k+ miles. Is it still your thought to go with the solution instead of another retro? I've thought otherwise, but am coming around to the solution as, well, ..the solution. I did the carerra tensioner hydrologic update on my 911sc, and then never thought about tensioners again. Same with the solution?
I recall that you take out the battery and remove the battery tray, and that the valve is right on top of the fuel tank. I had to do this due to a mouse nest and nibbled wire in this exact location. Great inde shop started top down when I was having your gas issue. There's a thread on the forum about this. He had to reconnect a chewed through wire and voila problem solved. Must tell you the wire was cheap, but the time spent on the actually job did not come cheap. Good luck...
judgejon replied to sky217's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Makes sense. Glad you found it, and hopefully not too pricey a fix. Cheers.
judgejon replied to sky217's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)were the tires broken in properly? how many miles on the car? how long have you had it? history of front end issues? could be a defective tire, or front end suspension issues. control arms? has the car been tracked? does the issue occur on a good straight paved road? are tires properly balanced? check tire play on a long straight good smooth roadway. sometimes a bouncing effect can happen if the tires are not properly balanced, and this might not be apparent at 50mph but would be noticeable at 65. good luck.
Still possible small cracks are doing you in. What happens after you wash car, or hose it off? Is car outside in rain, or garaged? What you described sure seems like classic coil pac issue. Good luck.
Yep, change out all coil packs.
judgejon replied to 356to966's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for this information. Thumbs up! I've actually done the lubrication of the front to rear bearing. It's not an easy access, but with some bending, more difficult as I get older, you can get to both seats from the back. both have to be fully extended upward to do this. I'm assuming that the height adjustment mechanism is on the same side of both seats. Porsche has done that with other stuff for years. Does this sound right to you? Also, I think there will likely be more room under the passenger seat. Did you unbolt both seats from the floorboards to tilt them back? And I'm guessing you also found some sort of a prop that fit to hold the seats on a tilt. Am I close? Cheers...
Hope you have solved this mystery. Curious to know the answer.
I know you've looked at the posts and checked your hoses, etc., but take a look at the wires on the top of the gas tank that go to a gas tank vacuum switch. Sure sounds like a switch is not opening to release pressure in the gas tank. Yes, I was the "mouse nest" guy that learned about this little switch the hard way. Others have mentioned that 996 cars do tend to fill very slowly, esp as the tank gets full. So a bit of gas overflow is not unexpected. Your issue as described is more than the usual situation. Good luck. Post up when you find the answer.
judgejon replied to johnmh's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Yes, luck has a lot to do with it. The fuel system is a bit bizarre, but you, and the forum, have figured it out. I would not have a clue. 3 related comments: the gas tank will not fill as quickly as with other cars. common problem is the valve that opens when the pump nozzle is inserted. If the valve does not open, check the wiring on top of the gas tank for rodent intrusion. Yes, I had a mouse chew through the wires. PITA to fix. I had a fire in my 911SC when a pebble caused the front A/C condenser fan to overheat. Explosion avoided because gas tank was full, not enough oxygen to cause explosion. Was your car actually shipped, literally, to Dubai? Good luck, ... and, cheers.
judgejon replied to martsink's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Bravo! Welcome to the forum.
judgejon replied to Gordon911's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)It's way more expensive, as expected, but I would likely go for the Porsche part. I have memories of replacing the turn signal switch in my older Porsche. Same issue, and in same price range. Having seen it come out of the older car, I might be tempted to try it DIY, but in reality would take it to a reputable shop. Good call, Loren. Good call, Joe.
