  1. Started the vehicle this AM around 10 to leave and the idle starts dropping right away but slowly while in park. Drops really low, then picks back up. Does this a few times while I'm going OH****. Put er in Drive and the idle drops again. It dies. I start it right back up and if I gave it gas same drop then dead. I'm going to test the other fuel pump with fuse on primary pulled. Last week we had humming coming from the fuel pump but it went away. While driving last day or so idle seemed rough. I'll be looking for the tech writeup on the fuel pump tests.
  2. I hate my pig but I love my pig, can anyone please help me before I send it for scrap. Over the space of the last 4 years of ownership my car has been in the Porsche dealers for 2 years in total with suspension problems, to cut a long story short this is now sorted and was due to a faulty replacement air bag being fitted. Moving on after 3 months of (almost) trouble free motoring this is what’s happening now and would love some advice as the closest porsche dealers is over 200 miles away from me. When I picked up the car from Porsche it ran out of petrol before I got to the garage at t
  3. Hi Guys, I am a proud owner of a 2010 Porsche Cayenne Base model and I have been having a intermittent Engine hesitation issue. the following is a detailed issue of whats been happening, any suggestions that would help resolve this is appreciated. About a month ago I was coming back from Roosevelt lake ,AZ which is about 3 hours from Tucson, it was a hot day 113deg, I was already in town and the gas gauge read about 1/8 of a tank and I was starting to move from a light when all of the sudden it felt like the engine stalled and came back on for a second then it did it again and my C
  4. Hi All, I am battling fuel pump (I believe) issues. I ahve replaced the pumps int he tank as well as the filter and sending unit. All coils and plugs have been replaced and one injector was bad (P0203 code). In any case I am still suffering form the "slump band" in the RPM range while under load (driving). GTS is a 6 speed manual so it's very easy to put the vehicle in the slump. I hooked it up to the Durametric this morning and took it for a drive. I utilized the logging feature and initiated the following: 1) Fuel Level (53) 2) Pressure Upstream of Throttle Body (902.7 mBar) 3) Fuel Hi
  5. I have a 2009 997.2 PDK Carrera 2 and am getting a loss of power and this error code: 2510: Fuel high-pressure control - adaptation. Value below lower limit value I believe this means my HPFP is dead and am looking for the workshop procedure for replacing the high pressure fuel pump HPFP. I have looked far and wide for a DIY tutorial on this, but found nothing. My local stealership will do the work for $900 labor plus parts. I have sourced the pump for $850 and want to do the work myself. The pump looks readily accessible at the back right end of the engine, facing the
  6. I have a 1998, ROW C2. Over the past two weeks I have noticed that the fuel gauge is not reading correctly. The gauge will read high (3/4) but as I drive, the gauge will slowly drop to the correct reading over about 15 minutes. As the car sits, either at work for the day or in the garage overnight, when I go to start the car, the gauge will read over 1/4 tank higher than when I shut it off. Then, as I drive, it will drop to where I think it should be (or remember where it should be). I plan to pull the sender this weekend and check the connections, but I don't think it is the float as why woul
  7. I’m having a weird ‘fuel thing’ with my 2001 Porsche 911… So, I’ve been thinking it gets terrible gas mileage, compared to my 986 Boxster. I expected slightly less, but, it seems pretty bad. Now, I can’t help but wonder if there’s actually something amiss about it. When I fill the tank completely—and I mean ‘topping it off’ to get every last drop in, my fuel gauge usually looks like this (see the first picture, 01). That picture was taken immediately after starting the car after filling up the tank (I was still at the pump). There have been occasions where the needle ha
  8. First time post... hope to start contributing to the forum now! 09 GTS with 93k and excellent maintenance history, recently getting long cranking times and sometimes rough idle at startup. Starter is working properly so we can rule that out - not sure what to tackle first, coils? fuel pumps? HPFP? Durametric codes: 1023 Ignition Coil D Primary/Secondary circuit - upper limit value exceeded 1026 Fuel high pressure implausible - value below lower limit value The 1023 keeps coming back when cleared but never throws a CEL, the 1026 has been very intermittent but will throw a CE
  9. I have a problem with the fuel door release/actuator. Whenever I lock the door I hear this loud noise coming from the fuel door. Only happens when I lock the door. Does anyone know how to access that actuator?
  10. I was driving a new to me 04 S in the mountains of Tennessee last weekend. With about a 1/4 tank (maybe a little less but the warning had not come on) going up or down a hill (I can't remember) on the interstate, the engine sputtered and quit as if running out of gas. No check engine light. Pulled to the side, waited. It started. Went 10 miles, same thing. Got to an exit. Got gas. No more problems. Other facts. I recently installed two new fuel pumps. Also, I cannot fill the tank at a gas station at the normal rate without the pump quitting -- as it there is a vent that won't let air be di
  11. Hi, My fuel door lock does not work when I lock the car. I have LPG so I don't use the fuel door much but I am worried that thieves might steal my petrol since it is pretty easy to syphon the fuel dry. The main problem I have is that I have a 100 litre gas cylinder in the trunk and therefore it is hard to get to the wall of the trunk to see if I can fix it as I have seen some posts on the topic. I was thinking of replacing the original screw on tap with a lockable one but in the Porsche manual it says that only original porsche taps are permitted. Is there any Porsche lockable tap availa
  12. Hi All, Just joined Your group and hope to share some experience with the Cayenne S, many thanks in advance for helping me out. Is just bought US version of 2005 Cayenne S and recently had some issues with the car. It first started with the starter which needed replacing. After that just after i got my car back a CEL showed up. At this moment i only know the error description not the code. It says that the car had problems with poor mixture of fuel and air and therefore the RPM goes little bit wild up to 1200 RPM. I keep on wondering if that is someway connected to the job that was
  13. I am about to lose my mind. Here's the story. I have an 02' Boxster S. I fill the tank, and it gets completely full... of course, only after manipulating the stupid pump handle to get the tank full as it shuts off every 2 to 3 gallons.... but I digress. I drive the car thereafter, and it runs perfect! Until.... just below 3/4 tank... should be approximately 4 gallons remaining. And then the car acts like it has freakin' water in the gas.... it quits, or stumbles, and shuts off for a moment, only to catch again... I though...ahhhh, I got water in my gas. So I put some fuel treatment into
