2000 VW Cabrio Fuel Pump Relay Location: Complete Guide to Finding, Testing, and Replacing It

The fuel pump relay on a 2000 Volkswagen Cabrio is located in the main fuse box under the dashboard on the driver's side. Specifically, it is a rectangular relay (often labeled as relay number 67 on some models ) that controls power to the electric fuel pump. If your Cabrio cranks but won't start, or starts and then dies immediately, the fuel pump relay is one of the first things to check . Replacing this relay is a cheap, fast fix that can save you from a costly tow.

Why the Fuel Pump Relay Matters

The fuel pump relay is a small electrical switch that sends power to the fuel pump when you turn the key. On your 2000 VW Cabrio, the relay engages when the ignition is turned to the "on" position, allowing the fuel pump to pressurize the system. Once the engine is running, the relay's job shifts—the fuel pump is then powered by the oil pressure sending unit . If the relay fails, the fuel pump never gets the signal to start, and your engine won't receive fuel.

This is a common issue on the 2000 Cabrio, which runs the 2.0L ABA engine . The relay itself is a wear item that can fail over time due to heat, vibration, or electrical fatigue. The good news is that it's a simple, inexpensive part to replace.

Step-by-Step: Locating the Fuel Pump Relay

Finding the relay on a 2000 Volkswagen Cabrio is straightforward. Here's exactly what to do:

1. Get into the driver's seat. The fuse box is located under the dashboard, on the driver's side. Look for a panel near the hood release lever and the parking brake. It is mounted vertically against the side wall of the footwell .

2. Remove the fuse box cover. The cover is a plastic panel with a rectangular shape. It usually has a small tab at the top or bottom that you can pull to release it. The cover may have a diagram of fuses and relays printed on the inside.

3. Identify the relay. The fuel pump relay is one of the larger relays in the box. It may be labeled on the diagram as "Fuel Pump Relay" or "Fuel Pump." On many 2000 VW Cabrio models, the relay is identified by part number 191906383C or 191906383 . It is often a black or blue rectangular box with 4 or 5 prongs.

4. Check the relay position. The relay is typically located in position 12 or 67 on the fuse box, depending on the specific vehicle configuration . If your fuse box cover has a diagram, look for the relay symbol (usually a square with a coil inside) or the text "Fuel Pump."

5. Inspect the relay. Once you find it, pull it straight out (it just clips in). Visually inspect it for any signs of corrosion, burns, or melted plastic. If the relay looks damaged, it needs to be replaced.

How to Test the Fuel Pump Relay

Before buying a new part, you can test the relay with a simple process. This will confirm whether the relay is the problem.

Method 1: The Swap Test

The easiest way to test a relay is to swap it with a known good relay of the same type. Look for another relay in the fuse box that has the same part number (like the horn relay or the ABS relay if they are the same style). Swap them and see if the car starts. If it does, you have a bad relay.

Method 2: Listen for Clicking

Have a helper turn the ignition key to the "on" position (do not crank the engine). Place your hand on the relay. You should feel a single click when the key is turned on, and another click when the key is turned off. If you hear no clicking, the relay may not be receiving power or is faulty.

Method 3: Use a Multimeter (Advanced)

Set your multimeter to measure resistance (Ohms). Remove the relay. Check the resistance between terminals 85 and 86 (the coil). You should see a reading between 50 and 120 ohms. If the reading is infinite (open circuit) or zero, the relay is bad. Next, apply 12V power to terminals 85 and 86 (using a battery or jump pack). You should hear a click, and the resistance between terminals 30 and 87 should drop to near zero.

Common Symptoms of a Bad Fuel Pump Relay

If your relay is failing, you will likely notice one or more of these symptoms:

  • Car starts and then dies: This is a classic sign. The relay provides power for the initial start, but fails to maintain it, causing the engine to stall seconds later .
  • Engine cranks but won't start: The starter turns over, but the engine never fires. You may not hear the fuel pump hum when you turn the key.
  • No noise from the fuel pump: When you turn the key to the "on" position, you should hear a brief humming sound from the rear of the car (the fuel pump location). If you don't hear it, the relay or the pump itself is likely the issue.
  • Intermittent starting issues: The car starts fine one day, but the next day it won't start at all. Then it works again. This is a telltale sign of a dying relay.

What to Do If the Relay Is Not the Problem

If you replace the relay and the car still won't start, the problem is likely elsewhere. The most common causes for a no-start after replacing the relay include:

  • A faulty fuel pump itself: The pump may have failed internally. For a 2000 VW Cabrio, the fuel pump is located inside the fuel tank .
  • A blown fuse: Check the fuel pump fuse, which is usually located in the same fuse box. The fuse is typically a 15-amp or 20-amp fuse.
  • A bad ignition switch: The switch sends the signal to the relay. If the switch is failing, the relay may not activate.
  • A faulty engine control unit (ECU): Less common, but possible. The ECU controls the fuel pump relay circuit.

Replacing the Fuel Pump Relay on a 2000 VW Cabrio

Replacing the relay is a simple DIY job that takes about 10 minutes. Here's what you need:

  • Replacement relay: Part number 191906383C, 191906383, or 857951253 . You can find these at auto parts stores or online retailers. Brands like Beck Arnley, TRQ, and Stribel make compatible replacements .
  • No special tools: Just your hands.

Installation Steps:

  1. Disconnect the negative battery terminal. This is a safety precaution to prevent any electrical shorts.
  2. Locate the fuse box under the driver's side dashboard.
  3. Remove the fuse box cover.
  4. Pull the old relay straight out.
  5. Insert the new relay into the same slot. Push it in until it clicks into place.
  6. Reconnect the battery terminal.
  7. Test the system by turning the key to the "on" position. You should hear the fuel pump prime.

When to Replace the Fuel Pump vs. the Relay

It is important to know the difference between a relay failure and a pump failure. The relay is a cheap part (usually $5–$15 at most auto parts stores), while the fuel pump itself is more expensive and requires more labor to replace.

If you have replaced the relay and the fuel pump still does not prime (no humming sound), the pump itself is likely dead. For a 2000 VW Cabrio with the 2.0L engine, the fuel pump is inside the tank. Replacing it requires dropping the fuel tank or cutting an access panel, which is a more involved job. Code readers may show trouble codes like P0192 (Fuel Rail Pressure Sensor Circuit Low) or P0230 (Fuel Pump Primary Circuit) to help diagnose this.
