Specialist vehicle diagnostics · North West
When the fault
doesn’t make sense.
We make it make sense.
Advanced diagnostics, auto electrical, ECU and emissions fault finding for motorists and garages. We test the system, build the evidence and plan the right repair route.
01 Warning light still on?
02 Battery flat again?
03 Parts replaced, fault returned?
04 Another garage needs support?
What we solve
Five specialist services.
One standard of proof.
Modern faults rarely stay in one box. Our workshop connects the electrical, electronic, emissions and mechanical evidence to find what is actually wrong.
Vehicle diagnostics
Warning lights, intermittent faults, non-starts and problems that have resisted the usual answers.
See what we testAuto electrical
Battery drains, charging faults, damaged wiring, network failures and electrical problems that come and go.
See what we testECU & module repair
In-house electronic testing, microscope repair, cloning, coding and programming for vehicle control units.
See what we testDPF, EGR & AdBlue
Root-cause diagnostics for DPF, EGR, AdBlue, NOx and emissions faults—not just another forced regeneration.
See what we testInspection reports
Independent vehicle inspections and clear written evidence for buyers, motorists, dealers and repairers.
See what we testProper diagnostics
A fault code is a clue.
Not a diagnosis.
Replacing the part named in a fault code can be an expensive guess. We follow the evidence until the underlying failure is understood.

Questions answered
Know what happens
before you call.
No. It means the system needs diagnosing. The blockage may be the result of another fault.
Read the answer →Can you test an ECU before replacing it?Yes. Powers, grounds, wiring and communications should be proved before a control unit is condemned.
Read the answer →Why is my new battery flat again?A module, circuit or charging fault may still be drawing or failing to supply power. We measure before replacing.
