There is a great misconception that to diagnose a fault, all that is required from a technician is to plug a diagnostic machine into the car and that it subsequently shows the fault codes telling us what to replace. This is extremely misleading.
The following pictures and subtext are of us diagnosing a misfire on a VW Golf, from this we hope to give you an insite into how we diagnose and rectify faults.
Hopefully this will help elaborate on the diagnostics side of the workshop and how we aim to confirm what is needed to be replaced before any parts are changed.
There can be a number of reasons why a cylinder might be misfiring; from a common spark plug fault, to a fueling issue or low compression for example.
Firstly we use the oscilloscope to check all cylinders, this is to make sure that the ECU has issued the code for the correct cylinder.
From our knowledge of graph reading and the use of voltage and amperage scopes, we can analysis the data and confirm that the misfire is caused by a faulty ignition coil.
