Absolutely brilliant service, my son broke down in Wallingford , Mark came out on a Sunday within a couple of hours to collect it, he then helped us source a second hand part as my son didn’t want to have a huge bill as going to university, we had to wait days for the part to get delivered to Mark but the day it was Mark turned it around and fixed on the day. I would highly recommend Bulldog Motors, 5 star service and such a good price too. I will be using Mark at Bulldog Motors for all our family vehicles.

FAQs

Can You Drive With a Warning Light On?

If a warning light appears on your dashboard, especially a red one, it’s important not to ignore it. Warning lights are your vehicle’s way of telling you that something isn’t right and delaying a diagnosis could lead to serious and costly damage.

A vehicle diagnostic scan uses advanced technology to check your car’s key systems for faults or potential issues. Modern vehicles are equipped with numerous onboard computers and modules that continuously monitor performance, emissions, and various components. When an issue arises, these modules store error codes, which a diagnostic scan retrieves. These codes are then compiled into a detailed report, helping us to understand any necessary repairs that need to be carried out. 

There are many different signs which will indicate that your vehicle needs a diagnostic check. If you suspect that there is an issue with your car but don’t know what, you should book a diagnostic check to find out what the problem is.

  • 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, or from the exhaust.
  • 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.

A diagnostic check can detect a potential problem with your car, even before a breakdown. It is also a quick, easy and accurate way to understand any issue with your car. This can include a dashboard warning light or strange noise.

Identifying the problem early will give you the chance to get it fixed before it can become a more expensive repair.
