Most reviewers praise friendly, punctual and professional technicians, describing efficient work and good value for money. A minority reported problems with booking/AA availability, missing service paperwork and disagreement over what a “major” service should include (notably the fuel filter), leaving some feeling overcharged. Overall the garage scores well for workmanship and price, but clearer communication about inclusions and quicker paperwork would resolve the main complaints.

What does a car diagnostic check do?

A diagnostic check is carried out on your vehicle by a mechanic, who will plug your vehicle into a specialised code reader. It can detect problems with your vehicle which may be difficult to spot manually.

The main components which are tested in a diagnostic check are the car’s:

  • electronic control units (ECUs) - these control various element of the car and its performance including engine running
  • emissions and exhaust sensors
  • braking system
  • electrical components such as central door locking
  • transmission if electronically controlled
  • ignition coils
  • throttle setting
  • fuel injectors
  • air flow and coolant

 

Why is a car diagnostic check important?

A diagnostic check is very important as it can detect a potential problem with your car, even before a breakdown. The computerised equipment scans your vehicle’s system to check for any faults, no matter how minor or major. A diagnostic test is a quick, easy and accurate way to discover any faults and will give you the chance to get them fixed before they turn into bigger and more expensive issues. When your car has a fault, this may show as a warning light on the dashboard. If the light goes out the system will store the fault code so the garage will find this when they do the diagnostic check.

What are the possible signs that your car needs a diagnostic check?

There are many different signs which will indicate that your vehicle needs a diagnostic check. Essentially, if you suspect that there is an issue with your car but don’t know what, you will probably want to book a diagnostic check to find out what the problem is. Here are some of the key signs:

  • Engine warning light - if the engine warning light appears on your dashboard, it’s important to take your vehicle to a garage as soon as possible as there is a wide variety of problems which the light may be flagging up.
  • Strange noises – any strange noises coming from your car need to be checked out before they turn into more serious problem. Some of these sounds may include; whining from the bonnet, abnormally loud exhaust, uneven engine noise, brake squealing or gear crunching.
  • Smoke - if you see smoke or steam coming from under the bonnet, your vehicle may be overheating.
  • Vibrating - if you notice any vibrating or pulling under your brake, the issue may be due to work brake discs or pads. However, it could also indicate a problem with your suspension or steering.

 

How long do car diagnostics take?

You can expect a diagnostic check on your car to take approximately 90 minutes. You may want to allow for more time though as the mechanic who will be carrying out the check might not be available to start right away.

How much does a car diagnostic check cost?

The price of a car diagnostic test can vary, depending on the garage that you visit. Each garage has a fixed price for diagnostic checks, ranging from £30 - £100.
