Your not going to like what i am going to say, but most turbo life spabs are about 75k miles. I would take it in for service and have them check your turbo, it may be time for a new one. Or it could be simple like you said and just have been a clogged air filter, but being that u have crossed thr 100k mark, i would have that turbine checked before you push the car again. Last thing you want to do is throw a blade into your engine and if you are leaking boost through a crack in the housing or something, that could very well be possible. One way or another, get the car checked by a trusted mechanic before you go WOT again.Hi all - I've searched the forum for this issue but didn't quite seem to find anything that fit. I have a 2014 ST3, creeping up on 125k miles. That's not a misprint. I've run it stock since ownership. It's my daily driver and I was 48 when I picked her up. I don't race it, but I drive it the way any red-blooded American should drive that car. I like to push it on the highway when possible and downshift and blow past some tool bag in a ricer when he's acting a fool. (which probably makes me a tool bag also)
I was driving on the highway yesterday, 92 degrees out. Open road for the most part. I'd been sitting and idling for a while waiting to pick my daughter up from soccer practice in the A/C. When we left we were in some city, stop & go traffic, then hit the highway. I was rolling along at about 60 mph and put the pedal down to pass. I had zero turbo boost. The gauge didn't move. Pegged at 0, and the car felt very sluggish. I was going to pull to the shoulder but was in a bit of traffic, so kept going keeping my foot out of the pedal. I was able to maintain speed but there was no, and I mean no available power to quickly increase speed. After about a minute of that, I felt the turbo come back. I tested it out and it felt fine and resumed normal driving. It went out again about 10 minutes later but again came back. The car ran normally after that for the remainder of our 45 minute ride. (had to drop one of her teammates off) Inexplicable.
I'm embarrassed to say my air filter was long overdue for replacement, and I put a new K&N in when I got home. (wasn't sure if this could influence this issue or not) I have not been able to replicate the problem. No engine light came on. No warning lights. I've read about the possibility of the charge pipe popping off which seems to be a common occurrence, but if that were the problem I obviously wouldn't have returned to normal operation.
Sorry for the long post but wanted to describe the best I can.
Also, after 124k miles I have had no significant issues at all with my ST. It's been good to me.
