Frequently Asked Questions
Usually a parasitic drain: something stays powered when the car is off — a faulty relay, a stuck module, an aftermarket accessory or a bad earth. We measure the current draw and isolate the circuit causing it.
Yes — intermittent electrical faults are exactly what fault finding is for. We test under load, wiggle-test connectors and read stored codes so we can catch faults that are not present every minute.
Both. Once we have traced the fault we give you a fixed quote, and if you approve the repair the £89 diagnostic fee is waived.
It varies — a clear drain can be found in an hour, while a deep intermittent fault can take longer. We confirm the time and cost before any chargeable work begins.
