Electrical System.
European specialists.

What it is and why it matters
Electrical System
explained.
European vehicles depend on a complex electrical network of modules, sensors and wiring, and a single weak ground or failing battery can cause symptoms that seem unrelated. Systematic testing finds the actual fault rather than replacing parts by trial and error.
What is included
What the service covers
- Battery, starter and alternator testing
- Parasitic drain testing for batteries that go flat
- Scan of control modules and network communication
- Inspection of wiring, connectors and grounds
- Fuse and relay checks
Signs you may need this
When to get it checked
- A battery that drains overnight
- Flickering lights or multiple warning lights
- Windows, locks or infotainment that work intermittently
- Starting problems
- A burning smell or blown fuses
