What we do
We read the hybrid and battery management systems, check the 48V / HV system status, DC/DC converter and starter-generator operation, and confirm which component has failed before any part is replaced.
Price
£100 per hour, charged in full hours. Book the first hour online; if the fault needs longer, we tell you before continuing. Diagnostics at the lab in Rainworth by appointment.
You get a written summary of the codes, live data and tests carried out, the confirmed cause and the recommended repair with a price. If the fault is in an electronic module, we can repair it in our lab.
Garages and fleets: trade rates and B2B work are priced individually – see For garages.
