I kind of doubt that. You're not getting error codes; you're getting a warning about one or more gauges. It'* hard to say for sure, and possibly you've got some transitory thing that'* gone away by the time you look down; e.g. maybe you're revving so high that your oil pump is cavitating or starving, and you have a temporary loss of oil pressure that recovers shortly thereafter. I don't recall if you've got a supercharged engine, but it could be overboosting and opening a wastegate.
But all that aside, you might want to take these occasional warnings as a hint that something far worse is not far off: by your own description, you have a high-mileage engine that you are pushing really hard, and it sounds like something is about to break here. When you approach redline, you're out of the best part of the engine'* power curve anyway, and are producing more noise than acceleration. It'* better to get the upshift and roll on the power at a lower rpm.
For example, a standing start in my SSEi will let me run the rpms way high before it upshifts to Second, but acceleration is nothing special. On the other hand, if I hold back a little on the acceleration until it goes to Second, and _then_ roll onto the gas, the g-force is definitely higher and I know I'm getting more bang for the buck.
