2020 Tiguan Won't Start - Just Clicks

Vehicle: 2020 Volkswagen Tiguan SE

My 2020 Volkswagen Tiguan SE is having a major issue this morning. When I try to start it, all I hear is a rapid clicking sound, and the engine doesn't even try to crank. All the dash lights come on, and the infotainment system powers up, but nothing else happens.

I tried jumping it with another car, and it still just clicks. The battery is only about a year old, so I'm a bit surprised if that's the issue. Could it be the starter motor? Or something else entirely?

Any advice or similar experiences with a 2020 Tiguan would be greatly appreciated. I'm stranded and need to figure out my next steps.

ClearTheCode admin answer: The rapid clicking sound you're hearing when trying to start your 2020 Volkswagen Tiguan SE, coupled with the dash lights coming on, is a classic symptom of either a low battery charge or a failing starter motor. Even though your battery is relatively new, several factors can still lead to this issue.

Here's a diagnostic approach:

  1. Battery Voltage Check: Even if the dash lights come on, the battery might not have enough cold cranking amps (CCA) to engage the starter. A jump start should bypass this, but if the cables weren't connected properly or the donor car's battery wasn't strong enough, it might not have worked. Use a multimeter to check the battery's voltage. A healthy battery should read around 12.6 volts. Anything significantly lower (e.g., below 12.0V) indicates a discharge.
  2. Battery Terminal Corrosion/Connection: Inspect the battery terminals for any corrosion or loose connections. Clean them thoroughly and ensure they are tightly fastened. A poor connection can prevent sufficient current flow to the starter.
  3. Starter Motor: If the battery is confirmed good and fully charged, the starter motor is the next most likely culprit. The clicking sound is often the starter solenoid engaging, but if the motor itself is faulty, it won't spin the engine. A common test is to tap the starter motor with a hammer (if accessible) while someone tries to start the car; sometimes this can temporarily free a stuck solenoid or motor.
  4. Ground Wires: A corroded or loose ground wire between the battery, engine, and chassis can also prevent proper starting.

When to see a shop:

  • If you've confirmed the battery is fully charged and terminals are clean and tight, but the issue persists, it's highly likely a starter motor problem. Replacing a starter can be complex due depending on its location.
  • If you're uncomfortable working with electrical components or cannot easily access the starter motor for inspection or testing.
  • If you suspect an issue with the alternator (which charges the battery) or other complex electrical system components.
