DIMO gives developers API access to Volkswagen Jetta vehicle data. Model years 2010 and newer connect with a DIMO device (DIMO LTE R1 or AutoPi). Headline signals include odometer, fuel percentage and vehicle speed.
DIMO gives developers API access to vehicle-state data: diagnostics, fault codes, battery and fuel health, odometer, and maintenance signals. The Volkswagen Jetta connects through a DIMO device, using either the DIMO LTE R1 or AutoPi, for 2010 and newer model years. Coverage for this vehicle has been tested. Vehicle owners consent to and control sharing, so builders get data with clear provenance.

No factory connectivity?
Volkswagen Jetta model years 2010 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
- New diagnostic trouble code
Build it
Query the latest Volkswagen Jetta 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 Jetta signalsconst data = await dimo.telemetry.query({ ...vehicleJwt, query: ` query { signalsLatest(tokenId: ${tokenId}) { powertrainTransmissionTravelledDistance { value timestamp } powertrainFuelSystemRelativeLevel { value timestamp } speed { value timestamp } } }`,});console.log(JSON.stringify(data, null, 2));Full walkthrough: Developer quickstart.
FAQ
Can I read fuel level remotely on a Volkswagen Jetta?
Yes, through a DIMO device. The DIMO LTE R1 and AutoPi both report fuel percentage, and the DIMO LTE R1 also reports fuel level in liters. Read it through the Telemetry API with a Vehicle JWT.
How do I track a Volkswagen Jetta with no connected services?
Install a DIMO device, either the DIMO LTE R1 or AutoPi. Once the owner shares the vehicle with your Developer License, you exchange your Developer JWT for a Vehicle JWT and query the Telemetry API.
Can I get check-engine light alerts for a Volkswagen Jetta?
Yes, with the DIMO LTE R1, which lists the dtc event and reports diagnostic trouble codes, DTC count and distance with MIL on. To receive alerts, create a webhook through the Vehicle Triggers API and subscribe the vehicle to it.
How do I detect idling on a Volkswagen Jetta?
Idling is listed as an event for both the DIMO LTE R1 and AutoPi. Query the Telemetry API segments resource with the idling detection mechanism, which requires a DIMO device and detects periods where engine RPM stays in the idle range.
How do I verify Volkswagen Jetta mileage?
Both DIMO devices report the odometer signal. Use the Attestation API odometer-statement endpoint to generate a verifiable odometer attestation, then retrieve it through the Telemetry API.
Which Volkswagen Jetta model years work with DIMO?
DIMO devices have been seen working on Volkswagen Jetta model years 2010 and newer. For older vehicles, contact DIMO for additional support.
Do I need hardware to get Volkswagen Jetta data?
Yes. DIMO lists no OEM cloud connection for the Volkswagen Jetta, so data comes from a DIMO device.
