Phil...

I've seen similar complaints on vw's (same two sensor oil pressure warning
system) that have the crankcase breather baffle in the valve cover blocked.

As blowby is produced & collected in the crankcase it builds up pressure
inside the engine, especially on the highway, because the baffle won't flow
it out fast enough.

Now for the life of me I can't figure out why the increase in crankcase
pressure doesn't help the light stay out instead of just the opposite...but
this is definitely what happens. New valve cover = light out.

At the speed you mentioned with a turbo engine there's going to be a fair
amount of blowby, and you may just be pushing the limits of the design.  Or
you might want to check the path of the crankcase gasses & see if all is
clean & well.

What are you using for oil??  We get a lot of unnecessary lifter noise &
oil light complaints from customers that have simply overfilled their
crankcase by a quart or used 10-30 weight oil (even synthetic).
Especially as the engines age, we seem to have the best results with 15-40
or 10-50,  synthetic or otherwise.

good luck...ned bennett
