guesswork
General garages guess. We diagnose.
We specialise strictly in auto-electrics, so we understand vehicle circuitry at a depth that all-rounder garages simply don't need to.
Dealer-level equipment
The same diagnostic and programming tools main manufacturer dealerships use, in an independent workshop.
Birmingham based
Conveniently located to serve the Midlands, with quick turnaround times on bookings.
Technical experts
We specialise strictly in auto-electrics, giving us a deeper understanding of circuitry than general repair shops.

No "parts-cannon" guessing games. We find the root cause and give a clear quote before any work begins.
Full workshop capability, electrical specialism.
From routine mechanical work to faults other garages turn away, here's what comes through our bay every week.
Mechanical Problems
General mechanical diagnosis and repair, carried out with the same precision we bring to electrical work.
Electrical Problems
Our core specialism — intermittent faults, warning lights and circuitry issues that other garages can't pin down.

From fault-finding through to full repair, keeping your engine running the way the manufacturer intended.
Clutch Repairs
Diagnosis and replacement for slipping, sticking or failing clutches, assessed properly before any quote.
Brake Repairs
Full brake system checks, pads, discs and ABS-related electrical faults handled under one roof.
A/C Recharge
Full air-conditioning regas and fault diagnosis to get cold air back before summer arrives.
The work that needs a specialist, not a spanner.

ECU Programming
Professional software updates and module initialisation, keeping your car's "brain" on the latest, most stable firmware.
Complex Wiring Repairs
From rodent damage to corroded looms, we trace and repair intricate wiring faults that standard garages often turn away.
