Engine Diagnostics

Let’s first dispel the myth that is commonly banded around by some in the motor trade that there is a single diagnostic machine which is able to carry out diagnostics on every vehicle that exits. That machine does not exist. Extracting fault codes is only the start of the diagnostic process. This should be followed up by following a guided diagnostic plan that compares actual values to expected values. Changing parts just because there is a fault code recorded against it and then sending the customer to the main dealer because the fault has not been rectified is not a diagnostic plan that we at FitnFix Auto recognise.

Excluding Euro 5 diagnostics (which we will come to in a moment), we at FitnFix Auto have seven different diagnostics tools that we use. Why seven? Well, each machine has its strengths and weaknesses on different vehicles, and if you are serious about fixing a vehicle accurately and for the first time, then this approach is the best way forward.

Euro 5 diagnostics is the latest technology which involves the Garage connecting your car to the manufacturer via the internet. Software updates, technical bulletins, guided diagnostics, wiring diagrams and known fixes can all be accessed. This technology comes at a cost with the manufacturers charging for use of their website services. However, with many faults now being solved by software patches, this technology is no doubt the best way forward. Currently FitnFix Auto is actively using Euro 5 diagnostics for VW, Audi, Skoda, Seat, BMW, Toyota, Jaguar/ Landrover, Peugeot, Citroen, Renault, Honda, Ford, Vauxhall and Kia with more to come in the near future.
