That's how the governor on a diesel works. Granted ours is a software governor, but hit that RPM and it'll sit there just like a John Deere. No rev limiter cutting spark like gas motors do.
If you take your '83 Benz up to its (mechanical) governor, you'll see it'll just sit at 4800-5000RPM with the pedal floored as the governor reduces rack travel to prevent the engine from revving any higher.
I still have to ask, what's the point of revving over 3800? You're just about at the power peak and there's no extra power north of there with the stock tune.
I think the redline on the tach is only there to keep people happy who are used to seeing it. Notice the tach on your diesel Benz doesn't have a redline.
