Electrical, Body & CAN Network Diagnostics
Feedback from garages and vehicle owners
Diagnostics by the hour – written findings and a repair quote.
Electrical, body & CAN diagnostics – Battery drain, intermittent electrical faults, lighting, central locking, comfort systems and lost communication between modules.
Typical symptoms
- Battery goes flat overnight
- Several warning lights at once
- U-codes – lost communication with modules
- Lights, wipers, windows or locking not working
What we do
We measure parasitic drain, power and earth circuits, and analyse the CAN network to find the module or wiring that is causing the fault.
Price
£80 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.
No VAT added – we are not VAT registered.
