Frequently asked questions about diagnostic inspections in St Helens
Read our answers to questions about diagnostic inspection costs, symptoms and more.
What does a diagnostic check in St Helens involve?
This very much depends on what the issue is, how frequently it occurs and also the location of the suspected problem. A mechanic will be able to go through the symptoms, evaluate the potential causes and reduce the likely culprit down enough to identify the culprit.
Once they have located the cause, if it is something that can be fixed there and then without the requirement of additional time and parts (and in most cases, this is the outcome), they will resolve it for you.
If the rectification requires parts and a return visit, the mechanic will provide you with a no obligation quite for the work and if you wish to proceed, they will arrange return visit with you.
How long does it take to do a diagnostic on a car?
A diagnostic inspection usually takes under 1 hour. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.
Do St Helens mechanics make house calls?
Yes, a mobile mechanic can call at your house and can inspect the car and diagnose a problem. If there is a minor issue the mechanic will endeavour to carry out any small fixes in the labour time quoted initially (the price of the inspection does not include any additional parts that may be necessary to fix the problem). Should there be any bigger problems the mechanic will provide you with a quote for the work and parts necessary to repair the problem.
How much should a diagnostic check in St Helens cost?
Cost for a diagnostic check is on average £65. Ultimately the cost of a diagnostic inspection depends on your car, location and problem on the car.

Should I use a mobile mechanic in St Helens?
Yes, a mobile mechanic is able to help with most repair or diagnostics work on a car. A mobile mechanic carries out repairs on vehicles at a location chosen by you (provided it is safe to work at). You would have the convenience of the mechanic coming to you, instead of having the hassle of taking your vehicle to a garage. Mobile mechanics are able to carry out most repairs this way.
The mechanics on our network are able to ‘Jack-up’ your vehicle to access the vehicle from underneath. Providing there is sufficient space around the vehicle, this won't cause any problems.
What can a car diagnostic test tell me?
A car diagnostic test can tell you if there are any problems with your car's engine, transmission, exhaust system, or other major components. For example, it can reveal whether the car has any faults, such as a faulty oxygen sensor or a misfire in the engine.
Is a car diagnostic free in St Helens?
You may find some garages advertising that a diagnostic is 'free' but there is usually a hidden fee attached to it. This is because diagnostic tools are expensive and the job takes about an hour or so to complete.
To avoid paying any "hidden" fees, you can book with ClickMechanic which will provide an upfront price for a car diagnostic inspection.
What does it mean if a warning light comes on?
Cars can have a range of warning lights on the dashboard - if it's red, it's a serious and dangerous problem and you should stop driving as soon as it is safe to do so. Yellow or orange generally means something is wrong, to be careful and get it checked as soon as possible.
The warning light symbol that illuminates will usually indicate what component is affected. A full list of warning light symbols and what they mean will be found in the owner's manual or vehicle handbook.
Can St Helens garages offer home collection and delivery for diagnostic inspection?
Yes, many garages in St Helens are able to offer collection and delivery for a diagnostic inspection. With ClickMechanic collection & delivery is free if your vehicle is drivable. Once booked a mechanic will pick up the vehicle on the day and time of your choice, do the work, and return the vehicle at a time convenient to you. Simply enter your vehicle registration number and postcode to get an upfront price for a diagnostic inspection in St Helens.
Can St Helens mobile mechanics do diagnostic inspection at my home or office?
Yes, St Helens mobile mechanics can do a diagnostic inspection at your home or office, provided there is a safe and sufficient space to conduct the repair or replacement. With ClickMechanic, once booked for a date and time of your choice, your booking will be offered to vetted mobile mechanics in your area.
