Diagnostic Check Details

Test Name Test Result Result 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 Passed The Manifold Absolute Pressure sensor data seemed correct at the time of testing.
Cleared codes time None reported as cleared Passed 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 Passed 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 testing is not supported on this vehicle ?? This car does not supply the battery voltage, therefore we cannot get the data we need to test the battery.
Alternator Test Alternator testing is not supported on this vehicle ?? This car does not supply battery voltage, therefore we cannot get the data we need to test the alternator.
MAF High RPM MAF was to low during test Failed The Mass Air Flow when the engine is not running should be higher than recorded, its is possible the MAF meter is damaged and this should be checked.
MAF Idle MAF values looked OK during the test Passed The Mass Air Flow when the engine is not running should be higher than recorded, its is possible the MAF meter is damaged and this should be checked.
EGR Idle The EGR did not show concerning errors for any duration during testing. Passed 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 good, the engine is running with fuelling normally. Passed 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. Passed Their are a lot of reasons for a fluctuating idle speed, such as a Vacuum leak, EGR valve stuck open, Dirty/sticking IAC (idle air control valve) (P0505), Engine temperature sensor, Knock sensor, Clogged EGR ports, Variable valve timing solenoid clogged/sticking or just needing a good service.
Idle Stability idle was slightly erratic, a nice long run or a service would probably rectify ?? 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. Passed 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 Passed No fault codes were stored on the vehicle
