FaultFixer for Traders:
Diagnose stock before it costs you

Buy on facts, not feelings. We come and carry out a full range of diagnostic checks so you can make sure of a vehicle.

We test engine components and functioning, find any hidden signs of wearing parts in all the major systems, and give you a clear, comprehensible document.
Our mobile unit can usually be there either the same day, or next day.

Engine Performance: Misfires, rough idling, power loss.
Sensor Issues: Faulty oxygen, coolant, or mass air flow sensors.
Fuel & Emissions: Rich/lean conditions, exhaust restrictions, catalytic converter problems.
Ignition System: Problems with spark plugs or ignition coils.
Other Systems: Can extend to brakes, airbags, and security systems.

Want to avoid an expensive mistake?
FaultFinder diagnostics show you the true condition, in plain English

Before you hand over your money, we’ll check the whole vehicle electronically, every system, every module and give you a plain-English report and 12 photos showing lights, tyres and under-bonnet condition. It’s your insurance against buying a lemon. If there’s a known issue or you’ve seen a light pop up on test drive, the Professional Fault Finder service will dig into the cause so you can negotiate the right price or walk away confidently.

Early Problem Detection: Prevents small issues from becoming major repairs. 
Accurate Diagnosis: Pinpoints hidden electrical or mechanical faults beyond simple visual checks. 
MOT Prep: Resets service lights and checks for fault codes that could cause an MOT failure.
