DIESEL ENGINE PROBLEMS
The innovation of the computer-generated fault diagnosis has led us to lose sight of the basic operating principles of the diesel engine. Unfortunately, the fault codes don't always pinpoint the problem but rather bring up an array of codes that could be either this or that. Being told: "we have tried this and it has not helped" or the best one, "sorry there are no fault codes so we can't find anything", is extremely frustrating and can be costly. Main Dealers, specialists and garages equipped with expensive and sophisticated diagnostic equipment still seem to struggle.
We have put together this guide to assist you with faults regarding diesel fuel injectors and pumps, DPF diesel particulate filter cleaning and other faults relating to diesel vehicles.
