Certified Technicians

Independent, and Specialist

BYDRepair.ie is Ireland’s independent BYD specialist. BYD went from nowhere to one of the country’s best-selling EV brands in three years, and the first Attos, Dolphins and Seals are now past their first big services and, in some cases, their first faults. The dealer network is still small and waits are long. We’re the alternative.

Our technicians are high-voltage certified and have diagnostic access to BYD’s systems, which matters because so much of what goes wrong on these cars is software. We understand the Blade LFP battery and its unusual charging advice, e-Platform 3.0, the 8-in-1 drive unit, the heat pump climate system and the DM-i plug-in hybrid drivetrain in the Seal U.

Servicing is done to BYD’s schedule and recorded so your warranty is protected. High-voltage battery warranty claims still go through BYD; we provide the independent evidence.

BYD Owners

“My BYD Atto 3 had a charging issue, and I wanted to understand what was causing it before replacing any parts. Having the diagnostic process explained clearly would make it much easier to know what needs attention.”

Sample BYD OwnerKildare

“I wanted to check the battery health on a used BYD before making a decision. Having a clear battery health report and understanding what it means would give me much more confidence.”

Sample BYD OwnerDublin

“With an electric car, I know that not every garage will be familiar with its systems. I wanted a specialist who understands BYD software, diagnostics and servicing, rather than someone guessing at the problem.”

Sample BYD OwnerCork

“My BYD started having problems with its heating, which is especially important during the Irish winter. I wanted to find out what was causing the issue and understand the repair options before agreeing to any work.”
