Vehicle data

Volkswagen Golf vehicle data API: signals, model years and connection options

Get API keys →

DIMO gives developers API access to Volkswagen Golf vehicle data. Model years 2008 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include odometer, vehicle speed and vehicle ignition status.

DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. The Volkswagen Golf connects through a DIMO device, for 2008 and newer model years. Coverage for this model is tested, not just expected. Once an owner shares the vehicle, you exchange a Developer JWT for a Vehicle JWT and read the data through the GraphQL Telemetry API.

No factory connectivity?

Volkswagen Golf model years 2008 and newer have no OEM cloud connection listed. For these years, a DIMO device (DIMO LTE R1 or AutoPi) plugs into the OBD-II port and streams vehicle signals once the owner connects it and consents to sharing.

See the developer quickstart for how owners connect vehicles and grant access.

Events available

  • Idling
  • Refuel
  • Harsh braking

Build it

Query the latest Volkswagen Golf signals with the DIMO TypeScript SDK. The vehicle owner must first share access with your app through DIMO Connect.

import { DIMO } from '@dimo-network/data-sdk';


const dimo = new DIMO('Production');
const tokenId = Number(process.env.DIMO_TOKEN_ID); // from DIMO Connect


const developerJwt = await dimo.auth.getDeveloperJwt({
  client_id: process.env.DIMO_CLIENT_ID,
  domain: process.env.DIMO_REDIRECT_URI,
  private_key: process.env.DIMO_API_KEY,
});
const vehicleJwt = await dimo.tokenexchange.getVehicleJwt({
  ...developerJwt,
  tokenId,
});


// Latest Volkswagen Golf signals
const data = await dimo.telemetry.query({
  ...vehicleJwt,
  query: `
    query {
      signalsLatest(tokenId: ${tokenId}) {
      powertrainTransmissionTravelledDistance {
        value
        timestamp
      }
      speed {
        value
        timestamp
      }
      isIgnitionOn {
        value
        timestamp
      }
      }
    }`,
});
console.log(JSON.stringify(data, null, 2));

FAQ

Can I read fuel level remotely on a Volkswagen Golf?

Yes, with a DIMO device. The Fuel Level signal (powertrainFuelSystemAbsoluteLevel, in liters) is listed on the DIMO LTE R1 coverage entry. Query it in the Telemetry API with a Vehicle JWT.

How do I track a Volkswagen Golf with no connected services?

Use a DIMO device, either the DIMO LTE R1 or AutoPi. After the owner shares the vehicle with your Developer License, request a Vehicle JWT from the Token Exchange API and query the vehicle's signals in the Telemetry API.

How do I detect idling on a Volkswagen Golf?

Idling is a listed event on both DIMO device entries. Query the Telemetry API segments resource with the idling mechanism, which requires a DIMO device. It treats periods where engine RPM stays in the idle range as segments, and maxIdleRpm lets you set the upper RPM bound.

How do I verify Volkswagen Golf mileage?

Both DIMO device entries list the odometer signal. Call the Attestation API odometer-statement endpoint (POST /v2/attestation/odometer-statement/:tokenId) with a Vehicle JWT, then retrieve the rawVC through the Telemetry API.

Can I get harsh braking alerts for a Volkswagen Golf?

Harsh braking is a listed event on the DIMO LTE R1 entry. Create a webhook in the Vehicle Triggers API on the events service with metricName behavior.harshBraking, then subscribe the vehicle to it.

Which Volkswagen Golf model years work with DIMO?

DIMO devices have been seen working on Volkswagen Golf model years 2008 and newer. For older vehicles, contact DIMO for additional support.

Do I need hardware to get Volkswagen Golf data?

Yes. DIMO lists no OEM cloud connection for the Volkswagen Golf, so data comes from a DIMO device.
