Full Diagnostic service

If your car suffers from any of the following, you need to speak to us first.

If a your vehicle is suffering any of the above complaints then an appointment is required for you to visit us for a complete evaluation consisting of standard preparation work, serial testing, parallel testing, formulation of results and Engineers report.

Visual Assessment

Before any test equipment is connected, a quick assessment is made under the bonnet, all vehicles have there own particular weaknesses due to poor design and all share weaknesses due to poor maintenance. Vehicle electronics have to operate in extremely harsh conditions, excessive heat, vibration and contamination are the worst enemies and all too often it’s a mechanical fault with a vehicle which can lead to a problem with a vehicle’s performance. Poor contact in wiring block connections due to water and oil leaks, dirty airflow meters due to oil contamination are all common. All these problems have to be fixed first before any electronic testing takes place.

It is quite often the case at this point we will advise the you the customer that some remedial mechanical work is required before further diagnosis is possible.

Serial Diagnostic

If all is well then we next connect a serial diagnostic to the serial connector of the vehicle. Here at West4Autos Limited we have a selection of serial testers collectively covering the majority of European and Japanese cars. All our diagnostic machines are main dealer level and have “Live data” capability and can be used to access other vehicle systems such as airbag, ABS, Body systems as well as Engine Management., however the most important thing is, is that all our diagnostic machines are upgradeable which means as vehicle technology moves on, so do we.

At this stage the appropriate tool is used firstly to see if any fault codes exist, if there are then they noted down. We DO NOT at this point replace the component the fault code refers to as many other repairers do, this practice can work out expensive both us the repairer and the you the customer and is unprofessional. The relevant code is noted and the circuit it refers to is noted, this is where the technician has to understand how a system works and how the components integrate, you have to work out what events would lead to that code being stored. To help us further we can then access the “Live Data” from the ECU and see if it is sensible. We have a database of “Live Data” to refer to as well as experience in knowing what to expect from sensors under various conditions.
