Test Indicator

VIN Check
|
Electronic VIN number reading is not support, please check the last 4 digits against the chassis plate.
|
|
The Vehicle Identification Number or VIN, is a unique identification tag that is mandated on all vehicles. This VIN contains all the information about where and when a vehicle was manufactured and also details about what specification was in the build. If the VIN number does not match the number recorded in the DVLA database, it should be checked for the reason why. Not all vehicles provide an electronic VIN, but it is recorded on the vehicle in several places such as under he windscreen on the dashboard, or in the engine bay on the VIN plate.

MAP Test
|
MAP sensor looked OK
|
|
The Manifold Absolute Pressure sensor data seemed correct at the time of testing.
|
|
Cleared codes time
|
None reported as cleared
|
|
When a time since a fault code cleared is displayed, the time is taken from a stored value in the Engine ECU. This does not nessecarily indicated an issue or problem, but should be queried or checked with the owner or in the service history just to be sure.
|
|
Distance codes time
|
None reported as cleared
|
|
When a distance since a fault code cleared is displayed, the distance is taken from a stored value in the Engine ECU. This does not nessecarily indicated an issue or problem, but should be queried or checked with the owner or in the service history just to be sure.

Battery Test
|
Battery test passed
|
|
During testing the battery was ok.
|
|
Alternator
|
the alternator is charging OK
|
|
the alternator output at Idle is as expected
|
|
EGR Idle
|
The EGR did not show concerning errors for any duration during testing.
|
|
The exhaust gas recirculation valve (EGR) is perhaps one of the most misunderstood parts on a modern engine. It is designed to help control pollution by lowering combustion chamber temperatures.
|
|
Fuel trim @ idle
|
Long term fuel trim at idle is low, the engine is trying to trim the fuel richer. Long term trim value
|
|
Fuel trim reporting shows how much work the engine ECU has to do in order to control fuel and ignition to meet emission requirements, a trim value greater than 15% could be an early indication of a fault.
|
|
Idle Speed
|
The engine idle speed was correct during testing.
|
|
A health engine should idle nice and smooth during warm up and when warm, we look at the idle stability to help identify irregular combustion which could indicate a fault.
|
|
Idle Stability
|
clean smooth idle
|
|
A health engine should idle nice and smooth during warm up and when warm, we look at the idle stability to help identify irregular combustion which could indicate a fault.
|
|
Eng Temp Sensor
|
The engine temperature sensor seems to be working ok.
|
|
Its important that the temperature sensor for the engine works correctly, otherwise the engine will be over fuelling.
|
|
MIL Light
|
The MIL light is not set
|
|
No fault codes were stored on the vehicle
