P052E Error in the control panel appears a light engine
20231228FUEL/PROPULSION SYSTEM
There is a problem with the fuel pressure sensor or wiring to the fuel pump control unit. This causes the fuel bay door to malfunction, meaning sometimes it won't open and sometimes it opens on its own. Today, my local Mercedes dealer (Mercedes of Seattle) quoted $5081.00 to repair this. See attached electronic quote that I rejected and then it disappeared but I saved a screenshot of it. The car has less than 20,000 miles on it. This issue first appeared about a year ago, indicated by a solid yellow warning light (vehicle icon) on the dashboard.
