Output of the fuel pump is inplausible?
2013 GLK250, 225,000km. Check engine light on. Scanned at an indy shop and it said P062A00. Output of the fuel pump is implausible.
Car drives fine, fuel economy is fine too. The fuel filter was changed at the dealership about 3 years ago. The indy shop said there may be a TSB on this and the dealership may have to load the software update.
I’m trying to avoid going to the stealership. Anyone had experience with this code and the fix? Any advice is appreciated!
edit: corrected the scan code.

I found topic about this code, who shows totally different code description.
Getting high-end MB codes description is not easy and sometimes shaving $150 for diagnostic at dealer might be money well spend.
Good luck

That code seems to apply to priming pump.
Since system is having 2 pumps in the line, the 2nd pump will cover some of 1st pump inefficiency.
But 2nd pump cost in the range of $3000, while 1st one in the range of $300, so replacing the cheaper pump can avoid replacing the expensive one down the road. I hope you get the logic?
What I'd do at this point is reading live data on both -low and high fuel pressure, but looks like you are due for priming pump.
Also if you are in US, your vehicle is subject to AEM and settlement, what would give you extended warranty.

The in-tank fuel lift pump?
DIY
One source for the pump: https://newparts.com/product/genuine...enz/2044702294 +-$500
, but there are others of course. You may also want to get a locking ring for the tank pump install.
Folks often have trouble reusing the one on the car.
Good luck!

Just an update. The indy shop recommended we try replacing the fuel filter and see if they solves the problem. So we did that and the CEL haven't come back in a few days!

Good to hear it the light is off.
I assume the shop read the live data to come to the conclusion? Something mid-level DIY owner should be able to do.

Back before there was all this fancy emissions stuff, and injection was mechanical, the cardinal rule for any performance issues on a Diesel engine was to change the fuel filter first. I guess the rule needs to be updated to cover implausible fuel pump output...

My general advise in old days was "start with the basics" meaning new filters, spark plugs and such stuff.
That was easy in old days, when DIY tune up would cost you a 100, or 200.
Today diesel fuel filter at dealer can cost above $500, when even $50 scanner will narrow the trouble with couple of minutes spend without getting your fingers dirty
