  1. 2002 911 Turbo (US) On a recent hot day after turning off the car I got an error on the console indicating an error with the engine purge fan. This makes sense as I understand this is activated when the engine compartment > 172 F. Hooked up the Durametric and saw the following (see 1st attachment): P1675 Porsche fault code 658 - Fault - engine purge fan I understand this can be a few things including the fan being broken, the temperature sensor in the engine compartment, or fuses B4 and C5 and the relay, or even a DME fault. Of these possibilities I believe my issue may be fuses B4 and C5 or the relay because when I'm in the Durametric software and I try to activate the "Engine compartment purge fan" (see 2nd attachment) it doesn't do anything. However, I tried to activate the "Fan Stage 3" as another test to be sure there wasn't a communication error and I can hear that big blower fan go on just fine as I would expect. The only strange thing is that when I try to activate the "Engine compartment purge fan" I don't get a new P1675 error after the previous code has been cleared, which I would have maybe expected. I'm lazy, so I first decided to check the fuse box because it's the easiest to access. I popped out B4 and C5 (see 3rd attachment) and sure enough I can see that B4 is blown. Now my only question is: Are these fuses special in any way? In other words, can I run up to AutoZone right now and buy one (I'm assuming this is a 15 amp)? Or should I wait until Monday and drive to the Porsche dealer to specifically get one from them?
