Tesla diagnostics and fault finding in Auckland

A warning on the screen, a noise nobody can place, or a car that will not do what it did last week. We diagnose Teslas properly, on a hoist and with the right equipment, and tell you what we have found before anything gets replaced.

Fault finding

What we can diagnose

Most faults are mechanical or electrical rather than mysterious. The work is in finding the cause instead of the symptom, which means testing rather than swapping parts until the noise goes away.

Warnings Alerts and error messages We read the alert, find what triggered it and tell you whether it is urgent, worth watching, or nothing at all.
Noises Knocks, creaks and rattles On the hoist, with the weight off the wheels and someone underneath while another works the steering. It is how you actually find them.
Electrical 12V, charging and accessory faults A car that will not wake up, charges intermittently or drops accessories is usually a low voltage problem rather than a high voltage one.
High voltage HV battery and charging health State of health, charging behaviour and range complaints, with a plain explanation of what is normal for the age and kilometres and what is not.
Drivetrain Motor, reduction gear and driveshafts Whines, clunks on take-up and vibration under power, tracked to the component rather than guessed at.
Pre-purchase Inspection before you buy A full look over any used Tesla, battery health included, so you know what you are buying before the money moves.

Something not right?

Tell us what the car is doing and we will find out why. You get told what we found and what it costs to fix before anything is ordered.

How we work

Diagnosis before parts

Anyone can replace a part. The value is in knowing which one, and Teslas are good at producing symptoms that point somewhere other than the cause. A creak that is really a bush. A range complaint that is really a driving pattern. A charging fault that is really a 12V battery on its way out.

So we test first. You get told what we found, what it takes to put right and what it costs, before anything is ordered. If we cannot find it, we say so rather than replacing parts on a hunch and sending you the bill.

Every model, from an early Model S to a current Model Y. If the fault is one we see often, we will tell you that too, along with what it usually turns out to be.

Everything else we do

Diagnostic questions

Can an independent workshop diagnose a Tesla? Yes. We have been working on electric vehicles for over ten years and Teslas are a large part of what comes through the workshop. Most faults are mechanical or low voltage electrical, and those are diagnosed the same way they always were, properly and on a hoist.
What does a diagnosis cost? Looking at a noise on the hoist costs nothing. Anything that needs real diagnostic time gets quoted before we start, and that time comes off the repair if you go ahead with the work.
There is a warning on my screen. Is it urgent? Sometimes. Call us and describe it, or send a photo. Some alerts mean stop driving and some mean book it in next week, and we will tell you which one you have.
Can you check my high voltage battery health? Yes. We report state of health, charging behaviour and how the pack compares to its age and kilometres, in plain language rather than a screenshot.
Do you do pre-purchase inspections on used Teslas? Yes, and it is worth doing. Suspension wear, brake corrosion, tyre condition and battery health all change what the car is worth, and none of them are visible in a listing photo.
★★★★★
Quick to inspect and resolve car issues. Super straight forward and transparent when explaining issues and the costs to fix them. The courtesy car is really helpful too, will definitely be going back for any and all issues! Thanks again.
