Identify the vehicle
Start with the VIN, drivetrain, engine, production details and available factory options.
Keep your vehicle details, service history and installed modifications together. Plan upcoming maintenance and prepare to buy or sell with the car’s history in view.

Your records stay yours to access. Changing plans does not automatically delete vehicle records or attachments. Previously saved records remain readable, with original downloads and backups. Existing Free editing commitments are preserved in the original browser. Check that your latest automatic backup completed, or download a copy, before changing devices, browsers or clearing site data.
Existing invitations and rewards keep their stated access and duration. Online research and new detailed reports depend on access and usage limits; retrieving saved records and backups remains available.
WERKAVON supports listed US 135i/135is, 335i, 435i, M235i and 535i configurations, including eligible xDrive, coupe and convertible variants. Choose your exact model and year in the app.
Use VIN details, service history, maintenance planning, Garage records, listing comparisons and PDF exports. Compare factory, current and proposed horsepower for supported N55 setups, or save a dyno report as your current baseline. Engine troubleshooting and modification research check your selected vehicle; shared N55 knowledge does not establish parts fitment.
Reviewed engine oil/filter and cabin-filter guides are available for their stated US F10 535i / 535i xDrive applications. Other guides remain under individual technical review. SUVs, the original M2 and other N55 applications are planned for later verification; diesel, N54, B58 and S55 cars are outside the current release.
