Even apparently simple problems require thorough investigation if you want to diagnose faults right the first time


The future of DPF servicing

Change can seem shocking at first, but is it the future?
Published:  08 May, 2017

Two months from now will bring my tenure in the motor industry to 49 years. I would like to think I have evolved, kept up with technology, enabling me to provide a professional service, enjoying customer respect and integrity. My focus has been the technical challenges, while my son David manages the commercial responsibilities.


Let go of my Lego

James looks at how the interconnected car can cause you headaches

"Electronic Lego" is a phrase that was introduced to me by an engineering manager when I worked for the diagnostic company Crypton around 25 years ago. In the late 1980s the Company had developed engine tuning machines which moved away from bespoke central processing units (the so called Big Box tuners) to a PC based system. The elements of the PC based system could not just be bought and fitted together (like lego) and be expected to work. The PC components and peripherals had to be carefully selected, including the compatibility of their drivers and software to ensure a robust PC based diagnostic machine could be created. Over the past 10 years or so motor vehicles have moved away from their previous Lego like construction, where replacement parts were free to be plugged in and replaced at will. The change was due partly to the modern vehicle being constructed as a rolling network of computers and partly to the advent of the factory fitted immobiliser, where transponder keys and the relationship between vehicle computers became prevalent.

Reasoning and diagnostics Part II

In this issue, Barney Donohew explores critical thinking
Published:  13 March, 2017

We began this journey last issue, so to recap: We need solid reasoning skills to carry out effective diagnostics; persistently good decision making doesn't happen by chance. Possibly out of convenience these skills are often underestimated and undervalued by people, both in and out of the trade. We must raise awareness of the discipline and precision of thought necessary for logical and critical thinking: so we can be better rewarded for our efforts; and to make sure they are consistently and properly applied.

Reasoning, arguments and hypotheses
We covered some fundamentals in my last article: we explain our reasoning using arguments, which contain statements supporting a conclusion; one type of argument, a deductive argument, should guarantee the truth of its conclusion (if it is sound); however, we need to use critical-thinking to check this, by making sure i) there are no other possible conclusions (which makes it a valid argument) and ii) the supporting statements are true.


Reasoning and Diagnostics Pt 1

Diagnostics is all about decisions. And what is a decision? It is a conclusion or resolution reached after consideration. Therefore, efficient and effective diagnostics is about drawing the right conclusions at the right time. How do we do that? Amongst other things, by making sure our logical and critical thinking skills are up to scratch. This series of articles aims to help us with that by looking at the principles of human reasoning.


The Tools for the job

I gave this topic some considerable thought before choosing to discuss not just a selection of tools we use, but also some tools we have designed and modified.

A couple of interesting workshop repairs have taken my fancy in the recent months, the first involves a BMW 530 common rail diesel.

If you've been reading this magazine for any amount of time, you'll be well aware of the obvious benefits of using an oscilloscope when diagnosing faults, but it is the less obvious benefits that with practice can lead to the correct diagnosis.


Access OE repair data

Technical data straight from the manufacturer

Alldata Repair gives independent workshops direct access to OE repair information via an online portal. The data is unedited - diagrams are not re-drawn and the info is uncut, what you see is the same information available to techs within dealer workshops.
