Fault codes read, then the fault found
A dashboard warning light means a fault code is stored in the vehicle's electronic control unit. Reading that code is the start of the job rather than the end of it. The code says which circuit is unhappy, not which part has failed.
Our qualified auto electricians use diagnostic equipment to assess complex faults on both petrol and diesel vehicles.
Faults we identify
Fuel injection problems
Engine management faults
Exhaust emission faults
Flat spot hesitation or misfire
ABS faults
What that warning light means
- Engine management
The engine control unit has stored a fault, often in the engine, fuel or emissions system, and a flashing light is more urgent than a steady one.
If it is flashing, slow down, stop somewhere safe and ring us on 01767 692798.
- Oil pressure
Oil pressure in the engine has dropped too low, and running it like that can damage the engine quickly.
Stop somewhere safe as soon as you can and ring us on 01767 692798.
- Battery or charging
The charging system is not keeping the battery charged, so the car may run out of electrical power and stop.
Stop somewhere safe as soon as you can and ring us on 01767 692798.
- Brake system
Either the parking brake is still on, or the brake system has a fault such as low brake fluid.
Stop somewhere safe as soon as you can and ring us on 01767 692798.
- ABS
The anti-lock braking system has a fault and may not work in an emergency stop, though normal braking usually still works.
- Tyre pressure
One or more tyres may be low on air, or the tyre pressure monitoring system has a fault.
- Coolant temperature
The engine is running too hot or the coolant is low, and driving on can cause serious engine damage.
Stop somewhere safe as soon as you can and ring us on 01767 692798.
- Airbag
The car has found a fault in the airbag or seatbelt system, so the airbags may not work in a crash.
Stop somewhere safe as soon as you can and ring us on 01767 692798.

Checks printed for your records
Any vehicle can be tested, petrol or diesel, fuel injection or carburettor, with or without an ignition distributor. Every test is fully documented and printed for your records, so you leave with a written breakdown of what was checked and what was found.
Petrol engines
Battery, starter motor and associated wiring
Battery charging rate, vehicle current draw and alternator
Distributor assembly, cap and rotor arm, plus ignition timing variation
Ignition module operation and coil dwell function
Coil output, together with spark duration
Spark plugs and plug lead performance
Carburettor and injection duration
Exhaust gas measurements, to MOT testing standard
Cylinder condition and relative compression test
Fuel injection variation
Diesel engines
Battery, starter motor and associated wiring
Battery charging rate, vehicle current draw and alternator
Heater glow plug, current draw, pre-glow timer check
Heater glow plug, post-glow timer check
Fuel injection pump operation, plus timing where marks are available
Exhaust smoke density measurements, to MOT testing standard
We are not a mobile service, and we will say so
We do not offer full mobile diagnostics. What we can often do is talk it through on the phone and tell you whether the fault needs a garage visit at all. If you are searching for a mobile auto electrician in Sandy or Bedford, ring us anyway. We will either help there and then or get the car booked in quickly.

For the diagnostic itself
What happens next
1. Tell us what it is doing
Which light, when it comes on, and whether the car drives differently. Ring us if you would rather describe it than type it.
2. We read the codes properly
On the ramp, with the full petrol or diesel check list where the fault warrants it.
3. You get the price before the repair
The diagnosis comes first, then a call with what it needs and what it costs.
4. You keep the printout
Every test is documented and printed, so you have the evidence whoever works on the car next.
Questions we get asked
It means a fault code is stored in the car's ECU. It does not tell you which part has failed, which is why reading the code and diagnosing the fault are two different jobs. We do both.
A steady light usually means drive on and get it looked at. A flashing light generally means stop and ring us. If you are unsure, ring us and describe it.
£144, which is £120 plus VAT, for the diagnostic itself. If it needs a repair you get the price before we start.
No. We can often help over the phone and tell you whether the fault needs a garage visit, but the diagnostic equipment lives at Tyne Road.
Yes. Batteries, alternators, starter motors and the wiring between them are core work here, and the test list covers charging rate, current draw and the alternator on both petrol and diesel.
