  1. I'm suffering from Secondary Air Readiness not complete on my 07 Cayman base model with 100k miles. I replaced my faulty DMTL pump 3 weeks ago and have since driven the car around 200 miles, with about 30 cold starts. There are no codes at all in Durametric, and I have done several long drives with the speed under 3000rpm. I also scanned the car with a Snap-on Modis and it reports the same. No fault codes but SAI not ready. The only symptom I have is that the fuel tank is difficult to fill without the pump clicking off all the time. I need to pass smog so I can re-register it, but I also need to replace a failing starter motor, for which I need to disconnect the battery, which will reset the DME, so I won't pass smog... Any ideas on how to get this thing to pass Secondary Readiness.
  2. I also did this and got the upgraded Beru coil packs with larger heads. I used a 1" boat transom plug off ebay for $5 to pull the oil tubes and replaced all the o rings. The whole job, including the correct OEM Beru coil packs, spark plugs, oil plug tube tool and o rings (all off Amazon or ebay) cost 30% less than the Porsche dealer was going to charge just to sell me the coil packs (no labor or tax!)
  3. I have the exact same codes in my 07 Cayman. Did you ever get to the bottom of it? I cleared mine and they always return. The car is stock, other than an aftermarket Pioneer headunit that often cause CAN errors. I have coded out the radio and related components, but these never go away.
  4. I had the same issue with my HPFP fault. Durametric hung everytime I tried to clear the code. I replaced the pump and then it worked fine. Seems like a software bug to me. I raised a trouble ticket with Durametric 2 weeks ago but they never got back to me.
  5. Where is this unit located on a 2007 Cayman? I have pulled off the front right wheel liner, the frunk plastics and cannot locate it. I have a spare unit ready to fit, just need to find where to fit it!
  6. Well, I couldn't find any information at all anywhere on replacing this, so I just worked it out for myself. Bought the pump from Porsche for $850 plus $150 core charge, pulled the exhausts off, removed the pump, installed the new pump, refitted the exhausts, took it for a test run. The car is transformed, a lot more power and no fault codes for the fuel pump. Took me 3 hours, Porsche were going to charge 4 hours. However, I now have brand new fault codes of : Siemens Digital Motor Electronics SDI3 Current Fault Codes 2310: Bar ignition module, cylinder 4 - Upper limit value exceeded Transmission - PDK Current Fault Codes C418: U0418 - CAN fault, brake They could have been there before though, my Durametric always hung when reading the codes, but now I have replaced the pump it scans this car properly without hanging.
  7. Thanks for the reply. Is there a procedure to check this? I have no information on how to measure the pressure or flow rate for this car, but I do have access to a comprehensively equipped pro mechanic shop.
  8. Thanks, I checked already this morning, no outstanding campaigns on my VIN
  9. 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 rear bumper. I am happy to write this up as a DIY with pics if someone can forward me the workshop manual pages or procedure?
  10.   This is the support topic for the DIY tutorial DIY to drain and refill rear differential and Tiptronic transmission. Please post here if you have any questions or feedback.  
  11. Sorry, I cannot find the part number for this unit anywhere, even my dealer parts counter and Pelican Parts doesn't know what a DTML is. Can you assist with that please? If you know the part number for the tank purge valve as well, I would appreciate it. I may as well change both out to get rid of this error, as I need to smog the car.
  12. Is that somewhere in the frunk behind all the plastics and near the gas tank filler? I haven't disassembled the frunk area on a Cayman before, most of my work takes place from underneath.
  13. Thanks Loren. Where is the DMTL located? Will this cause the difficulty in filling the gas tank, as none of my previous Caymans had this issue?
  14. I have a 2007 Cayman base model with 100k miles, with the CEL light on for P2402. I replaced the gas cap as it had quite a lot of cracks in the rubber seal. The CEL came on shortly afterwards with the following symptoms: 1. P2402: Pump motor final stage tank leak diagnosis module in Durametric. 2. It is hard to fill the gas tank from about 1/2 full onwards without the gas pump clicking off all the time. 3. 'Check engine light' and 'Visit Workshop' messages pop up. What parts would I need to investigate and where are these located?
  15. Did this ever get a resolution? I am in the same boat. A noisy whining that is worst between 40-60mph in 4-6 gear. Pushing the clutch reduces the whine a lot, but not eliminated. My car is a 1999 996 C4. A mechanic nearby has suggested differential side bearings. Can anyone recommend a shop that can repair these in the Bay Area? I can R&R the transmission myself, but I am not sure I want to get involved with shimming bearings to adjust the backlash or preload.
