Our diagnostic workshop is equipped with the same state-of-the-art technical equipment and information as all the main dealers.

We can resolve all your faulty behavior problems on the majority of vehicles. For example, diagnosing the warning lights from your dashboard which can result in a MOT failure.

Diagnostics is only one of our core strengths within our business. This means that you’ll get better service and a faster, less costly repair than if you take your car to a general workshop/garage.

We invest heavily in technical training, up-to-date equipment and workshop information so that we can offer you the best service possible. We continually strive to keep up to date with the latest technology and realized software, in order to provide the best service.

Please contact us for a no-obligation discussion, or call to book in for an initial diagnostic assessment.

Myths about the check engine light

Myth 1: The trouble codes will tell you what sensor to replace

This is an expensive frame of mind. The Check Engine Light directs your attention to a problem. A trouble code description then directs you to a circuit or system. It will not tell you what sensor to replace. It is about as vague as stating that a book is in the automotive section of the library. You now know what section to go to, but no clue where to look yet. That is why there are flow charts or trouble code trees and diagrams to guide you through specific tests to determine what is the problem. Often it is a broken wire, loose connector or some other cause, than the sensor itself.

Myth 2: When the check engine light comes on, it always means you have to replace something

One of the first things that needs to be done when diagnosing the check engine light is to clear the trouble codes, road test the vehicle and then recheck the trouble codes. If the codes come back, then start with the lowest number code and go through the flow charts and diagrams.

And the last Myth…

Anyone who has experienced this will have potentially spent a lot of money on replacing oxygen sensors, only to find out that this is not in fact true. You will not know, nor will anyone else know, what the problem is until you have had the trouble codes correctly diagnosed. Even if it is an oxygen sensor code, most of times there are other causes for this code to come about, for example Vacuum leaks, poor fuel quality, and low or high fuel pressure.

Vacuum leaks, poor fuel quality, low or high fuel pressure, a compression problem or a plugged catalytic converter could cause it. If the oxygen sensor is bad, then replacing the sensor still does not finish the repair. If an oxygen sensor failed, then there is a problem with the emissions of the engine. Usually when an oxygen sensor fails, it is because it has become contaminated. Contamination caused by an engine that is not running properly. So you will still need to determine where the originating problem came from. More often than not, there will be no trouble codes for that problem and it will not be evident without some specific tests.

We hope that this will clear up some “myth-conceptions” of the check engine light, because we have seen many people all over who have been telling folks that it is on because of this or that. We’ve tried to locate where it is that they buy their crystal ball, but alas, we have yet to find a reliable crystal ball. Until then, we rely on good old common sense, a good scan tool and a quality information system.
