That's twice he's been told. Hopefully.. he's paying attention (it's a real PITA to find you're not able to remove the fill plug after draining the TC.. but - you only make that mistake once.) BTW - Steph - when you're done - please post your results here. I'd like to keep a running total on success with this.1 point

Hmmm, I'll check with the indy (good relationship now) and see what he says. I know that to do the fuel adaptation it requires the immobiliser code. That's not something to mess with, even he was very, very careful when doing it and the value had to come from Porsche NA. I have mine now but wouldn't dream of using it, a $4000 DME isn't in my plans to replace. The pump isn't that hard to install, just tight space for one of the bolts. I had the intake off of mine to do the thermostat and water pump so it was really not bad at all. Just make sure you get all the broken plastic pieces out of there.1 point

Yep that's it, its called the Evap Purge Solenoid Valve. About 100 dollars. Also have a good look at the wiring to the plug, Thomas had it break inside and was causing him some trouble until he found it and replaced the plug. When you unplug it just use a multi meter to test the two pins to measure the purge solenoids resistance it should be quite low maybe 5-15ohms. If high resistance, open circuit or nearly 0 then it faulty for sure. The plug will likely be negatively switched so with ignition on you can test the 12v supply is present if you use test between one of the pins and a ground/engine block. (This will generate a p0441 code so expect that and clear it once plug is reconnected and cycle ignition key on off on first) The plug ground will be via the dme so testing that to engine block/ground won't give you anything tangible I don't think. If you don't find anything unusual buzz the solenoid out using two pieces of wire connected to the + battery jump point on the engine bay right side under the beauty cover. Note the positive and negative pin on the purge solenoid by knowing the + wire on the plug and which pin it goes on to.1 point

To eliminate the P0441 simply replace the purge valve. This could also be an contributing or causing other running issues and definitely is the reason for hard starting after fill up.1 point

Scrap the above. I missed a key piece of info which I found on another forum, the fuel pump will not auto switch from left to right or visa versa. You have to cycle the ignition off and on with one of fuses out to get the other pump to run. Duh brain. Anyway did the test again today and been running on the right pump only, no change to running stutter symptoms. So I'm Barking up the wrong tree. To be sure that my pump are working correctly I still need to make up a pressure test kit. Sherlock Holmes said ilminate everything possible and what your left with must be the cause. This could take some time ...............1 point
