Delphi took to the stage at Automechanika Birmingham earlier this month to address one of the biggest misconceptions in the aftermarket: that Teslas are too complex for independent garages to service and maintain.
There are now some 10000 Teslas on Irish roads with many more expected in the coming months. With Teslas first appearing in 2017 they are now firmly in aftermarket territory and Delphi used its live sessions to demonstrate how routine Tesla servicing is not only possible for independent workshops but presents a growing opportunity.
“There’s a lingering belief that Teslas are somehow out of reach for the independent sector,” said Luke Garratt, UK Technical Services Manager at Delphi. “We wanted to show technicians that with the right knowledge and training, these vehicles are entirely serviceable and, in many ways, easier to work on than some may think.”
The sessions began with an overview of Tesla model identification, helping technicians distinguish between the Model S (2012 - 2023), Model X (2016 - 2023), Model 3 (2019-) and Model Y (2022-). With Tesla’s production timelines overlapping and subtle design changes introduced over the years, correct identification is a crucial starting point.
Technicians were also given a detailed look at Tesla’s service mode, accessed directly through the infotainment system. Delphi demonstrated how this allows access to vital service functions and diagnostics, giving technicians the confidence to navigate the system safely.
One area that caught the attention of many was Tesla’s smartphone app integration. With owners able to access real-time data such as speed, location and even camera footage, the session highlighted the importance of understanding how these systems operate to avoid accidentally triggering alerts or causing concern.
High-voltage safety was another key focus. Delphi emphasised that no technician should attempt work on a Tesla’s high-voltage components without at least a Level 3 EV qualification. However, many everyday service items such as brake fluid, coolant, battery state-of-health checks, and the inspection of tyres, suspension and brakes can be carried out safely without touching any high-voltage systems
“It’s easy to forget that all electric vehicles suffer many of the same wear-and-tear items as any other vehicle,” said Luke. “And unlike most vehicle manufacturers, Tesla makes its service information portal freely available. There’s no login needed, no subscription. That’s a game-changer for independent garages.”
Delphi service parts for Tesla are available from factors nationwide.
