Vauxhall Diagnostics

Vauxhall Diagnostics


Concerned that there is a fault with your Vauxhall vehicle? Perhaps a warning or engine light has appeared on the dash or maybe your car just isn't running quite right? Diagnosing the problem can be a difficult and often frustrating task, one that requires a Vauxhall independent technology specialist like Dack Motor Group.

In 2010, Dack Motor Group originally opened as Vauxhalist, a dedicated Vauxhall specialist. Because of this, we can guarantee you that all of our technicians are trained to Vauxhall standards and have a wealth of experience with these models. This makes us the leading choice for Vauxhall diagnostics in Lincoln & Coventry.

We have the latest Vauxhall diagnostic equipment, information and continually trained technicians. This ensures that we can carry out an accurate diagnostic test on your Vauxhall. 


What is a Diagnostic Check?

A diagnostic test is a service which is performed in order to discover any issues with your car. There are a diverse range of problems which can be discovered during a diagnostic and it is a vital aspect of car repair. 

During your Vauxhall diagnostic check, one of our professional qualified mechanics will plug your vehicle into a specialised code reader. This diagnostic system will analyse the health of key components and can detect problems with your vehicle which can be challenging to spot manually. This will allow us to correctly diagnose and fix your vehicle, so it is safe for you to drive away once repaired.

Once your diagnostic check is complete, we will advise you as to either what the issue is, or what is required to identify the issue.


Dealer Diagnostic Equipment

Dack Motor Group uses dealer diagnostic equipment including the MDI and Tech 2 to extract the information required from your vehicle. We then have a workshop full of other equipment which allows us to get to the bottom of the issue.

Additionally, we have a live subscription to Vauxhall TIS (Technical Information System) which allows us to check for known issues and all Vauxhall technical information. 


Why Do I Need A Diagnostic Test?

As a service, a car diagnostic is essential for finding faults quickly and ensuring your safety. A diagnostic test will be able to find problems which may be unable to be detected manually, which means it could identify a problem that is developing before it turns into a serious issue.

Having a diagnostic test carried out can save you a huge amount of money in the long term as the longer a problem goes without attention, the worse it will get.

We will always be absolutely thorough when diagnosing vehicles, standing by our motto 'test, not guess!' 


How do I know if I need a diagnostic check?

There are several signs which can indicate that your vehicle needs a diagnostic check. If you suspect that there is an issue with your car but don’t know what it could be, it would be a good idea to book a diagnostic check to find out what the problem is.


Some of the key signs on your Vauxhall could be:

  • Engine warning light - if the engine warning light appears on your dashboard, it’s important to book in for a Vauxhall diagnostics check as soon as possible as there are 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 problems.
  • 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 weak brake discs or pads. However, it could also indicate a problem with your suspension or steering.
