Diagnostics

At Pontardulais MOT Centre we are determined to find the cause of the issues your facing. Our diagnostic assessment allows us to determine the best route for finding the fault(s) with your vehicle, while also keeping you in control. We gather some information from yourselves via our tailor made questionnaire, once booked and dropped off, we then carry out our assessment.

Why do we need diagnostics

Fault Assessment & Repair

Once the assessment has been completed, we will contact you with a cost for repairing the fault or provide our test plan to locate the issue. Every vehicle is different—sometimes, we are fortunate to find the fault within the first hour, but more complex issues require additional time.

We use multiple tools to carry out our assessment, but our first task is always to confirm the customer’s complaint. Once confirmed, we check fault codes, live data, and wiring diagrams. From there, we conduct the necessary tests to determine the root cause of the issue.

We utilise a range of dealer tools to keep the majority of repairs in-house, saving you the hassle of taking the vehicle elsewhere for software updates or coding.

With an on-site auto locksmith and auto-electricians, we employ specialised diagnostic methods and tools that many other garages do not use.


DPF Doctor

DPF Doctor Network Official Logo

We are part of the DPF Doctor Network, conducting unique assessments to identify the root cause of your DPF issues.

Unless there is a vehicle fault, environmental factors, or an unsuitable driving style, the self-cleaning Diesel Particulate Filter should not cause problems. However, if you do experience issues, we are here to help.

The DPF assessment provides you with all the necessary information, whether it is an advisory for potential future issues or an immediate fault that needs rectification. Once assessed, we provide a report detailing our findings and the recommended next steps.

After completing the necessary repairs, we take the vehicle on an extended drive while monitoring its performance to confirm that all issues have been resolved. We then ask you to drive the vehicle for 500-1,000 miles over a two-week period before bringing it back for a free recheck.

AC Diagnostics

Our unique approach to AC fault finding has even caught the attention of our industry instructors!

When you book your vehicle with us for an air conditioning service or assessment, we conduct a multi-step process to evaluate the health of the AC system. Once satisfied, we perform functional tests to confirm whether the system is running at optimal performance. Only after these tests are complete do we proceed with refilling the system, ensuring no gas is wasted.

By performing tests and servicing in stages, we can inform customers more quickly about any necessary repairs or issues they may be facing before proceeding to the final refilling stage.
