Hello friend! Great job! I bought myself a GLB 250 2020 35 thousand kilometers! The engine check lit up today!I read the errors (P1CEF (85),P1CE5(77),P219D(77),P219D) I observed a slight instability in the operation of the car engine! Sometimes it didn't start the first time! Sometimes I felt light tremors at low speeds! As if increased fuel consumption! Do you think I have this case? Thank you for your great responsiveness! You're great!

Remove the spark plugs and see how they look. If they look burn I would start by replacing them. If you still have a problem most likely you will need a cylinder head.

Yeah I hear you. This happen mostly within 10k miles to 40k miles which would still be cover under the warranty. Once is done you don't have to worry about it. They made the parts better. This is why you don't buy the 1st or 2nd year of that model. Wait at least for the 3rd year.

I have a GLB 250 (2021 model and 22k km). The engine check light has turned on. Service said it is because of fuel system. But no exact reason. Then I made them turned the check light off 3 days later it came back on Then 1 week after it turned off by itself. I used the for 200km and full the tank. After 2 weeks light came back again. The average consumption is 17liter / 100 km. Isn’t it too much? What could be the issue?

Thermostat! The original Thermostat has a wire filter which gets a lot of dirt collected and don't let coolant pass through. You have to replace the Thermostat. The new Thermostat doesn't have that filter in it. So make sure it's off when you get the old one out.
