Vehicle diagnostics in Leeds
What is a diagnostics check?
When car warning lights illuminate on your dashboard, an engine diagnostics check can help identify the problem before more serious damage occurs.
Most modern vehicles today contain an on-board computer known as an Engine Control Unit (ECU) which continually monitors the performance of the vehicle. Sensors all around the vehicle report back to the ECU if there are problems such as low fluid levels or increased engine temperature. When an issue is identified the ECU generates an error code. The relevant dashboard warning lights will then be displayed.
There are literally hundreds of potential error codes that can only be read by specialist vehicle diagnostic equipment. While a warning light may display on the dashboard alerting you to an issue, a diagnostics check is required to understand the full extent and cause of the problem.
At Queenswood Service Centre we use state of the art equipment for vehicle diagnostics which can read the engine fault codes in your ECU’s memory. Our trained technicians can then suggest any necessary repairs to get you back on the road and rectify the error so there’s no need to pay vehicle dealership prices for your diagnostics check next time a dashboard warning light appears in your car.
Common diagnostic scenarios
- Engine management or emissions warning lights
- ABS, airbag, and other dashboard warnings
- Misfires, rough running, or high fuel use
- Electrical faults with windows, locks, sensors, or drains
- Pre-MOT checks when a light could cause a fail
Diagnostics FAQ
How long does a diagnostics session take?
Typically 60-90 minutes with a fixed diagnostic fee; we then quote for any repairs separately.
Do I need to leave the vehicle?
You can often wait for shorter checks, but for deeper faults we may ask you to leave the vehicle so we can test properly.
What if the fault is intermittent?
We review symptoms with you, check stored data, and test drive if needed; if it does not appear on the day, we will agree next steps.
How do you share results?
We explain findings in plain English and can share photos or video where relevant before you approve any work.
Need precise answers?
Call or send an enquiry about any dashboard light or running fault and we will advise the best next step, with clear costs before repairs go ahead.
