First turbo no longer kicking in

I'm at ~52,000 miles (conveniently outside of warranty) and near the end of my commute into work this am, my first turbo would no longer kick in. No SES lights or errors though. Anyone else experiencing this with similar mileage? I've seen a lot mentioned about a faulty boost hose, faulty boost actuator/valve, etc and really hoping it's something minor...
Outdoor temp was 28F and commute was mostly highway driving (about an hr commute). I also just filled up a full tank of diesel from my usual stop...
Any info is much appreciated.

Is the car stock? Or have you been running a tune?

Think the same thing happened to me about a year ago. With about 12K on the odometer. There was just no power or pull until the car got up to speed and the second turbo kicked in. (I'm talking 10 second 0-60 or more) Same situation with no warning lights coming on. Brought car in and they said EGR malfunction and they did the pre-recall work and reprograming. This was before the recall was officially going on. I thought for sure it was turbo malfunction but car has run great ever since, so I'm not exactly sure what went wrong and how the EGR issues translated to the feeling of a turbo going out. Probably need a more engine literate person to enlighten me.

The good news...When I left work to drive home, the car ran like normal again. I couldn't reproduce the lack of first turbo boost problem again... I'm hoping it was just a one time anomaly, but I'll definitely have to keep a close eye on. I've put an additional 130 miles on since and still all good. I'm running a tune, but the car has been flawless since the remap. The whole event was deflating..as it seemed like my car turned into a prius when I tried to pull away from a stop light. I thought I even heard it chanting, "I think I can" "I think I can.."

I had to have the low pressure controller replaced on my car this week. The first turbo was not working and when they diagnosed it, they discovered that the low pressure controller had failed.

BTW. my car has been in the shop three times since the beginning

(AZ335D) Did you notice any warning signs prior to the first turbo going out due to the low pressure controller, or did it just die out one day? With regards to the three times your car has been in the shop, were they related to the turbo? Thanks

There were no warning signs. I had the car in and they replaced one of the fuel injectors. I picked the car up and got about 1/2 block and the SES light came on again. That time it was the low pressure controller. The car was pretty slow getting up to speed from stop, but that is all fixed now.
