Question 2

What are the most common car electrical faults in Highgate vehicles?

Accepted Answer

Common electrical faults we see from Highgate drivers include flat or failing batteries, faulty alternators, blown fuses, malfunctioning central locking, dashboard warning lights, broken starter motors, and issues with headlights or tail lights. Modern vehicles also frequently suffer from sensor failures and ECU-related faults.

Question 3

How long does an electrical fault repair take?

Accepted Answer

Diagnosis typically takes 1–2 hours. Simple repairs may be completed the same day, while more complex electrical work — such as rewiring or ECU replacement — may require an overnight or next-day appointment. We'll always give you a realistic timeframe upfront.

Question 4

Is it safe to drive with an electrical fault warning light on?

Accepted Answer

It depends on which warning light is showing. Some electrical faults — such as a battery warning or engine management light — can indicate problems that may leave you stranded or cause further damage if ignored. We strongly recommend booking a diagnostic check as soon as possible rather than continuing to drive.
