Electronic Stability Control warning lights came on today in instrument cluster. Then after a while, a message came on that ESC Inoperative -see operator's manual which says take it to dealership.
I was driving about 35 MPH and pulled into a left turn lane and stopped, but realized I needed to go straight so turned hard to the right and nosed into the next lane and stopped. When I drove away, the ESC warning lights came on.
Drove to destination (about 15 minutes) and stopped for a couple of hours.
When I left drove for about 40 minutes and lights never came back on.
Do I really need to take it to a dealer? Thanks.

This is often caused by a wheel sensor or its rusted out pulse ring.
To figure out exactly what's going on, you car should be scanned to read faults.

What happens if I don't get the ESC checked out? Assuming the warning does not come on again.
Just took car for a short spin, lots of turns and so forth but slow speeds. No warning lights at all.
I may have inadvertently turned off the ESC when first warning came up, but would that have brought up the ESC Inoperative. See Operator's Manual notice?
Hate to take it to dealer for them to tell me NPF (No Problem Found) and charge me a hundred or more.

Yes, I hear you! Of course NPF, pls come again...
This is why every owner should have his own scanner to get quick answers.
Transient faults can take a few driving cycles to get confirmed and logged. The initial occurrence serves as a gentle warning something is going marginal.
From here you pay a quick diagnosis fee to get an estimate for the initial round of parts swap.
Timeless classics ✌️

I think ESC is self-diagnosing itself at each start, so if the issue is cleared, it should not come back.
I have such lights when I take my diesels for smog, where technician has to disable all traction programs.
When I pick it up, I have whole discotheque on dashboard, what will clear after restart, or 2.
But still, how can you drive modern vehicle without a scanner ?????

For me. El Cid is the nickname for my college alma mater, not the movie.
I just can't believe that you don't have a scanner that can do MB specific codes. You have some intermittent problem. It may or may not come back again, probably will at some point as something is probably marginal at this point and will probably fail again or go bad just enough to trigger the same problem. They're pretty cheap these days, down to $50 now, inflation must be moderating, was up to $65 at one point. That's a surer bet than taking it to the dealer and gambling whether they'll find the problem or not. It may be stored as a previous code or not so using the scanner is much cheaper than going to the dealer.

A thick wallet helps, or maybe two commas in a bank account.

Well I don't think you need two commas but obviously the more commas you have the easier it is. I don't think I've come close to 5 digits in repairs over the years. The W212 is definitely more reliable than the W211.
(currently on sale for $120 but only for another hour).
it gets codes out of all the obscure control units, and can read/display live data. it operates completely standalone without a phone or laptop, and can fetch updates to itself over wifi.

I paid $49 for my HT200 (sibling of AP200) and it does very advanced troubleshooting.
I put the licence on Sprinter, so for my sedan, I am using older scanner as I did not have any bigger issue with it, but if need arrives -$20 for additional licence is still a bargain.
One of older scanners is $3 dongle and $5 for Torque Pro app update. Amazing how much the $8 invested can scan.
