Reasons for stalling at start-up for a Mercedes Glc-Class

We are going to build this article with two different paragraphs, one detailing the mechanical reasons which can make your Mercedes Glc Class stall at start-up, then the second the electronic reasons.

1: Mechanical causes that cause your Mercedes Glc Class to stall

We will discover, in this paragraph, the various parts that could make you stall at startup if by chance they were damaged.
The idle actuator: Its mission is to regulate the air in the engine when it is at idle speed so that it does not suffocate or stall. If by chance you feel that your engine is grazing a little before stalling, it is quite possible that this is the cause.
Battery : If your car starts fine and then stalls after a while, it's not the battery. It will only be in question if your Mercedes Glc Class starts to stall immediately after switching on.
Consequently, check carefully on this side.
Also remember to simply consult your dashboard which will allow you to derive information concerning the lights potentially on when your Mercedes Glc Class stalls at start-up.

BSM case: This is the information exchange platform for your Mercedes Glc Class. It is unlikely that this is the cause because it is rather reliable. The vast majority of breakdowns related to this box are cars that stall while driving.
BSI box: The BSI unit will centralize information and translate all these different languages ​​for the overall management of vehicle functions. This could only be the cause if your Mercedes Glc Class did not start at all.
Calculator: This is the central element of an assortment known as the “on-board system”. The primary function of a computer is to provide the correct "grammage" of fuel with each stroke of the engine piston. Several on-board systems electronically manage the various functions of the vehicle. There are between 30 and 80 on each car! Be careful with this part because some professionals tend to blame this part because they are not able to find the real fault. It would be enough for one of its sensors to be damaged on your Mercedes Classe Glc and for the computer to be suspected. If possible, consult a second professional if by chance you are asked to replace this part because it is expensive.

TDC sensor: Its mission is to identify the mode on which your Mercedes Glc Class is located so that the fuel is sent accordingly. This could be worn, or simply clogged. Check its condition to be sure.
Alternator: Logically, this should be out of the question, because it is thanks to it that the battery starts the car.
