  1. 40bar at idle. Answered this is one of your other posts asking roughly the same questions about your situation :) It's 99% your HPFP. It sucks. Just went through this entire ordeal in March. Like my grandpa used to say- Getting the answer I want to hear won't change the problem or the solution... - Matt Sent from my iPhone using Tapatalk
  2. Should call for and receive 40mb at idle. Mine would sometimes get that, I'd think GREAT then go for throttle up and it'd bog down... Replacing the entire LPFP system that was 8 yrs old helped quite a bit and was absolutely needed, but ultimately it was the dreaded HPFP. Call Porsche and see if they'll help you. They sent me a $500 voucher simply for asking. Rebuilt units (new really) can be found from dealers for around $800usd. Installed it myself. Been running fine since. Future prevention measures: refill my fuel tank now at 1/4 or higher vs letting it run until the light comes on and chan
  3. No CELs initially. First symptom: random long starts. Second: smell of burnt plastic. Third: more consistent longer starts. Then: total failure at highway speed. Scared the heck out of me. Nursed it home. Diagnosed left fuel pump (primary) bad, swapped it out. Improvement. Then fuel filter. More improvement. Then right pump & FPR. Better still; all the while dreading the ultimate reality that my HPFP was also bad. Finally swapped out a rebuilt Porsche HPFP (thing was actually new) and talked PCNA into helping me out. They sent a $500 voucher. Why? Because I asked nicely. Also my car previo
  4. Check if one of your fan speed switches on the console is sticking. Mine was stuck in the down position and did the opposite of what you described. Quick cleaning and all better... Hope this helps. - Matt Sent from my iPhone using Tapatalk
  5. Ended up ultimately being my high pressure fuel pump. Decided to replace my entire fuel system + HPFP. Not a bad DIY. Moderately expensive. Tight spaces to work.
  6. SOLVED Just wanted to inform anyone having issues with play in their steering that my problem was solved by simply tightening the etorx bolt that attaches the steering shaft to the rack. Was quite loose. Easily accessible from underneath the car. Couple turns of the extended socket wrench with an e14 torx and she’s good as new. Sent from my iPhone using Tapatalk
  7. Hi, wondering if anyone in the Chicago area has access to a PIWIS? If so can I please pay you to check out my driver's side door? Door was replaced by previous owner. Per motor werks: drivers side door module needs to be activated (so my mirror and courtesy lights function) MW wants $250. F that. Thank you in advance! - Matt in Barrington (2009 Cayenne S)
  8. That's awesome! Feels good doesn't it. Just did my trans fluid week before last. Plugs week before that. Side note - been dealing with slop in my steering gear. You guys ever deal with that before on a ZF rack? Center play/wiggle left and right about 2 degrees. Drives me nuts. Any idea if I can simply adjust the yoke at the rotary valve? 2009 Cayenne S
  9. Sure - I went through any and every connection under there. Radio, nav, lights. Pulled/unscrewed each, sanded with light grit sandpaper, sprayed with electrical cleaner and reattached. This included any kind of plug attachment. Sent from my iPhone using Tapatalk
  10. Lewis regarding the taillight, did you remove EVERY connection under the spoiler, clean with abrasive and reseat/reconnect including the earths? That finally did the trick for me... Sent from my iPhone using Tapatalk
  11. Tech at Porsche here in Chicago said they usually reflash there dme, adapt throttle and fuel trim. Said it'd be an hour ($250). Thankfully I didn't have any issues. Maybe it's just your dme needing an update? I still might get mine flashed. Just hit a 150k miles and notice my ox sensors are overly sensitive... Sent from my iPhone using Tapatalk
  12. I had a feeling it was your LP system. VDO Siemens (OE) pumps can be found for $240/each, filter $120, L piece for filter $20, regulator $150 and new seals $20/EA. It's a pretty easy job. Do it with less than a quarter tank. Wear nitrile gloves. More than happy to talk you through it...
  13. Interesting. I put a -GX rebuild in today and the pulled out a -07... How often are these things going bad?? That -07 couldn't have been more than 3 years old! Also interesting is that the failed unit had an 'expiration' date of 2020...? So all in, I replaced both LP pumps, filter and regulator and the HP pump and stopper. And changed the oil. It was a fun DIY. I learned a lot. Car runs normally again. Joy. Next up, trans fluid and filter followed shortly thereafter by a full brake job. Sent from my iPhone using Tapatalk
  14. INFORMATION: - If it is not possible to drive at the specified speeds, the adaptation ranges 1 and 2 can also be achieved by increasing the engine load relative to the specified speed. A defined fuel throughput must be achieved for the adaptation to be completed.- The specified time stipulation of 15 sec. is cumulative, i.e. the time may also be broken down into 5 + 5 + 5 seconds, for example. 6. Fuel high-pressure adaptation range 1 must be reached: gradually approach the speed range of 60 - 85 km/h (40 - 55 mph) and maintain this for at least 15 sec. The Tester indicates when the value chang
  15. Don't think my durametric can perform an engine torque loss adaptation. Throttle adaptation, yes. Sent from my iPhone using Tapatalk
  16. FYI - Doing my HPFP tomorrow morning. Talked to Porsche today. They recommend throttle adaptation and engine torque loss adaptation after hpfp replacement. Function found under DME using PIWIS tester. Sent from my iPhone using Tapatalk
  17. I feel your pain. My guess is the regulator and both low pressure pumps are on their last legs. Did you do a flow test on your low pressure system? Sent from my iPhone using Tapatalk
  18. Thank you Lewis. Love that tutorial! Any idea which Hitachi pump a 2009 Cayenne S uses? I know the Porsche number, but I'm guessing Porsche IDs marking up this up by at least 200%. As it stands, my current plan: Grabbing a rebuild later this week. Porsche offered me a $500 voucher to help. Why? Because I asked. Over the phone. I was blown away. Thank you PCNA :) New is about $1200, rebuild is $820 plus core. So... Doing the swap myself + voucher - rebuild = huge savings and healthy fuel supply. Fingers crossed. I'll let you know how it turns out. Any luck with your 3rd brake light? Could be yo
  19. Love this place. Lots of window shopping on their website. Been waiting to need something from them and think now is the time. I hope they take the voucher. Their rebuilt pump incl. core charge is the most affordable I've found by roughly 20%. Pricing out rotors and brakes as well and had to do a double take to make sure they were really that affordable... 2009 Cayenne S
