    Always take my car to Gents garage for my MOT’s as it’s over the road from where I work, what a great bunch of staff there, really helpful and willing to help when you have a problem as l did with my VW Tiguan . I thought it needed a new thermostat or sender unit but they fixed it for me and l didn’t need either. Heating system is working great now and they also did an air conditioning... Read More

    Arrived unannounced with a puncture and Graham and his team rearranged their work schedule to be able to sort my puncture and get me back on the road. Graham himself carried out the work before going to lunch . Once again great service. Thanks.

    I’ve used Gent’s garage for years now for each of the cars I’ve had and I am very happy with the service they provide. I completely trust the work that they do on my car and I’ve never incurred any unnecessary expense. Everyone I’ve met there is friendly and It’s also a bonus that I get a lift to work when I drop my car off.

    Exceptional service after my car failed it’s MOT yesterday. Chris and Andy really looked after me. They took the time to explain the defects with my car, provided a quote and answered all my questions. I decided to go ahead with the repair. I expected to have to re-book for another day but they managed to get the required works done that same day! Wonderful service from a garage of genuinely... Read More

Don't you just plug in a computer?

Sure, we do plug in a computer to help with the diagnostic evaluation. However, it goes far deeper than that.

Because a single fault code can have a lot of different causes, we follow an 8-step process to guarantee that we can discover the root cause of the issue on the first attempt. And, that keeps the diagnosis at the lowest cost.

What’s involved in a diagnosis?


Consultant – To gather first point information to help our technicians understand the symptoms, we consult with you.


Inspection – We inspect your vehicle with you; this ensures that our understanding of the fault is in line with yours.


Interrogation – Your vehicle computer systems are interrogated for current and historic faults.


Technical Product Bulletins – Based on the interrogation results, we use technical product bulletins to help reveal any known problems.


System Data Evaluation – Our technicians then pinpoint any aberration, so we understand which tests your vehicle needs to go through.


Reference – We’ll refer to our technical information systems to identify test specifications.


Testing – This is the most intensive process, as we use all the information we’ve gathered to undertake tests using serial data tools, oscilloscopes, and pressure and flow gauges to pinpoint the exact cause of the problem.


Assessment – With the test results in hand, we can make an extremely accurate assessment of your problem, at which time we’ll call you to discuss our analysis and the next steps.

How much does a diagnostic evaluation cost?

This depends on the level of testing needed. However, the initial evaluation is £96 inc VAT.

If any further testing is required, we’ll discuss it with you first.
