How is Tesla remote diagnosis performed?

We have a subscription to Tesla Toolbox diagnostics and can perform this in most cases to discover the cause of the fault before the car arrives at our workshop.

NOTE

When performing a remote diagnosis, we do not have any physical interaction with the vehicle itself. We only use the data and logs the vehicle has already reported to Tesla's servers.

To perform remote diagnostics on the car, we need the car's registration number and the email address associated with the car (the one used in the Tesla Mobile App).

We send out a remote diagnosis request, and the customer receives an email from Tesla Toolbox called "Owner Authorization Request"

The customer must press the "Review" button and is then sent to the website to log in to their Tesla account.

After logging in, the customer can choose to approve or reject the request.

When the request is approved, we and the customer will receive an email informing us of this within a few minutes.

We then pull the logs from the car to read data the car has reported up to 2 weeks back in time.

After a review of the data and the errors (warnings) the car has reported, we perform a thorough inspection of relevant signals that will point to the root cause of the problem.

After performing remote diagnosis, we send results to the customer by email, with screenshots of the diagnosis included and the cause of the problem explained, along with a quote for repair.
