Hi guys, I recently got a 2003 300gt with about 54k km on it, all pretty solid so far. One interesting thing i noticed is a wiff of coolant coming out of the vents when the heater comes on with a low fan setting. If it the heater is on but with a high fan setting/flow then the smell goes away (doesn't smell without the heater when using A/C). I am wondering whether it is the core, or just whether perhaps the first thing to try replacing is the microfilter. I haven't checked the Coolant level yet, but that is next on the agenda as well. Guess I don't want to go overboard as the heater core looks to be connected with the A/C and therefore a PITA to replace, but has anyone had a similar experience and should i just try replacing the Microfilter?

Sorry to trawl this thread up from the past, I have been using your codes to browse and I can say they aren't accurate for sedans past 03 (believe me I just bought an '03 with a D code Option 16 and it doesn't have side airbags, it has the heated seats with full leather option, but i already knew that before buying it). I did however find a better way by accident today, it is quicker and it doesn't require translation: go here http://nissan.epc-data.com/ type in the japanese VIN in the section that says: "Please enter full frame number:" you will then get to a page like this: (here is one i prepared earlier with alot of options) http://nissan.epc-data.com/skyline/hv35/6820-vq30dd/?frame_no=hv35-204441 if you look at the "Spec code" section it will give you the option code (similar to those in the original post) if you hover over it, it will give you a tooltip with an explanation of which code is which IN ENGLISH. Enjoy! and I assume this does more than just V35s!
