So.. I'm on my 8months of owning this WRX and the first issue was a fluid leak shown here (intercooler hose problem) http://forums.nasioc.com/forums/show....php?t=2422067

Then last week same problem occured but this time with additional issues!

1. On half throttle whistling noise can be heard on driver side (boost leak maybe?)

Where are you located? What about the sound at WOT? Is it much louder? Is it a whistling sound or like a high powered kazoo type sound? I have a sort of whistle but it's not a boost leak... the turbo spooling is definitely louder at colder temps. Do a search for "wrx whistle" and you'll find quite a few threads on this same issue with videos and sound clips for your comparison.

2. Changing gears on half throttle produces a loud popping noise on the exhaust.

I have Nameless's catback on my '12 sedan with a 5" muffler and resonated midpipe, and I get these pops too. It's my understanding that the cause is hot air meeting with cold air as the exhaust leaves the pipe. I didn't really like them at first but they've grown on me. If I go 60-100% throttle for a few seconds and let off it make a pretty aggressive growl/pop.

Any of you 2011-2013 owners experienced this ?
Dropped my car off the dealership this morning and they said there is an ECM update or system they have to do and look at the leaks..
The ECU update is for the coolant thermostat, my understanding is that it's related to emissions in certain states.
Car is completely stock..
