The diagnostic evaluation process


The process starts with a client consultation to give our technicians the opportunity to gather important information about your vehicle.


Our diagnostic tech will carry out a vehicle inspection, along with you, to ensure that our understanding of the fault is in line with yours.


A thorough scan of the vehicles computer systems takes place to find current and historic faults.


Technical product bulletins are consulted. This will highlight any known issues for the model and will flag any available software updates.


An evaluation of computer system data allows the technician to see anomalies and identify the tests required to establish the cause.


Consultation of all technical information to show any system specifics required for testing. Wiring diagrams are consulted at this point.


From here on, tests are carried out in the logical order using all the technical equipment we readily have to hand, such as serial data tools, oscilloscopes, pressure and flow gauges.


Once all the test results  are collated, we will make an accurate assessment of the problem and contact you with a thorough analysis and our recommendations.

Don't you just plug in a computer?

The use of a computer is obviously an important part of the evaluation (point three in our process) and faults can be highlighted here.

However, one fault code could have many causes which is why the tests in point seven are essential to identify the exact cause.

Comprehensive testing is an essential element in the process and ensures a first time fix with the lowest possible cost.

What does a diagnostic evaluation cost?

The final cost of diagnosis is calculated on the number of tests required for your vehicle, and every vehicle is different.

Initial evaluation costs are £75 inc VAT which typically covers the above points from one through to eight.

We will contact you with our recommendations if the number of tests required exceeds the initial evaluation quote.
