Diagnostics


Does your engine misfire or judder causing the engine management warning light (EML) to come on?

Chatham’s Pentagon Motorist Centre can diagnose and read an ECU’s fault code with a scanner at our workshop in Medway, we are in the centre of Chatham close to the town centre. Diagnostic readings are extremely important when it comes to diagnosing warning light faults or running problems, but it does not detract from basic checks that need to be carried out first.

Basic Checks:

The most important basic check that needs to be carried out first before a code reader is reached for and plugged in, is water and oil levels. Low oil or coolant levels will allow an engine to run hotter than normal; this factor alone can cause a sensor to malfunction. If the vehicles levels are all ok then a code reader or scanner can be plugged in.

Diagnosis:

The diagnosis does not end there, should a fault code be present then it is with this information that a technicians work begins. Understanding the code and what sensor relates to what part is a key factor in this next stage. This is what a technician has been trained to do. Pentagon’s technicians not only have had the initial training but they have a wealth of experience on working with many different vehicles.

Testing:

The information drawn from your vehicles Engine Control Unit (ECU) can now be analysed and further checks may need to be carried out. Connection problems through electrical plugs or wiring needs to be tested before a part or sensor can be condemned. Testing a sensor or part is normally the next stage. The draw back here is always going to be, the time involved in conducting some testing procedures.

Decisions making:

On occasions an informed decision may have to be made, to spend time on testing or to replace the suspected faulty part. A typical example would be to spend time and test a camshaft sensor that may take £30 – £60 in diagnosis time or simply fit a new camshaft sensor at a cost of £20 plus the time for fitting.

This is when a good garage comes up with the correct decision. We at Pentagon Motorist Centre rely on the Technician to inform the Service Manager and between them the decision is made to either test or replace. I am proud to say that in the majority of cases the correct decision is made.

Has your vehicle developed a lighting fault or has a bulb failure light appeared on your dash board? Electrical faults can be problematic, why not book you vehicle in and let our technicians find the fault for you from our Medway workshop in Chatham.

So from just a simple fault code read or a full diagnostic check Pentagon Motorist Centre from Chatham in Medway is the garage to use for all your vehicles electrical problems.
