What are the reasons why the Volkswagen Sagitar cannot start?

The reasons why the Volkswagen Sagitar cannot start: 1. The battery is dead, causing the inability to start; replacing the battery can solve the issue. 2. Damage to the fuel pump, fuel pump control unit, or relay. 3. Damage to the engine sensor. 4. The engine lacks cylinder pressure, leading to failure to start; overhauling the engine can resolve this. 5. Incorrect gear position. For automatic transmission vehicles, the gear must be in P or N position when starting; if placed in R or D position, the car will not start. The Sagitar is a joint venture sedan brand under FAW-Volkswagen, with body dimensions of 4544mm in length, 1760mm in width, and 1461mm in height, and a wheelbase of 2578mm. In terms of appearance, the front face of the Volkswagen Sagitar adopts the Volkswagen family's large-mouth front design, paired with two newly designed xenon headlights, giving it a striking look from the front. The body lines are quite rounded and full, with arcs smoothly extending from the front bumper to the rear, enhancing its grand car demeanor.
I just encountered a situation last week where my Sagitar wouldn't start, and it turned out to be a battery issue. Actually, the common causes are limited to a few: dead battery being the most common, especially for old batteries over three years; depleted key fob battery causing signal detection failure; starter motor damage resulting in freewheeling sound; fuel pump failure leading to no response when cranking; severe spark plug carbon buildup or ignition coil malfunction; automatic transmission not in P gear can also lock the system. In my case, being able to start after jump-starting confirmed it was battery depletion. I recommend first checking the dashboard light brightness - dim lights indicate battery issues. Always remember to turn off AC and headlights before shutting down the engine, especially in winter when low temperatures particularly drain the battery.
A friend who runs a repair shop often receives rescue calls for Sagitars that won't start. According to him, 90% of the cases are due to battery or starter motor failures. Oxidized battery terminals causing poor contact are very common, and can be fixed by removing and sanding them with sandpaper. Fuel system issues like clogged fuel injectors or overdue gasoline filter replacements can also be the culprit, especially for cars that have refueled at small gas stations. A lesser-known cause is a faulty crankshaft position sensor - when this component fails, the ECU doesn't receive the ignition signal. Here's a practical tip: when the key remote's battery is dead, pressing the key against the push-start button can enable emergency ignition.
