What to Do When a Volkswagen Tiguan Won't Start?
2 Answers
Here are the solutions for a Volkswagen Tiguan that won't start: 1. Jump-start: Position the two cars close to each other, connect the positive and negative terminals of the batteries, turn off all auxiliary electrical devices in the car, and start the vehicle with the dead battery. 2. Push-start: Utilize a downhill slope, turn on the ignition before starting the vehicle, shift the transmission into second gear once the desired speed is reached, quickly release the clutch pedal and accelerate. Reasons why a Volkswagen Tiguan might not start due to human operation include: dead battery, empty fuel tank, or incorrect gear position. Apart from improper operation, other possible causes could be a faulty starter motor, fuel pump supply issues, injector problems, sensor malfunctions, etc. For these more complex situations, it is advisable to seek professional assistance.
My Volkswagen Tiguan wouldn't start the other day, which gave me quite a scare. First, check if the battery terminals are loose or have green corrosion - this is a common issue. If you only hear a clicking sound when turning the key without engine response, it's likely a dead battery; you can test this using jumper cables connected to another vehicle. If the dashboard lights up normally, the battery is fine, then check the starter or relay - these components tend to wear out in VWs. Sometimes it's the fuel pump failing - listen for a humming sound under the rear seats when attempting to start. If absent, you might need to check the relevant fuse in the fuse box. I'd also plug in an OBD scanner to read trouble codes - once I found it was a faulty crankshaft position sensor, and replacing it fixed the issue. Also, weak key fob battery might trigger the immobilizer to lock the engine, just resynchronize it. Most importantly, avoid repeatedly turning the key to prevent circuit damage, and consider professional help or towing for safety.
