About Diagnostics Chippenham

Modern day vehicles are covered in hundreds of sensors constantly monitoring and reporting back the vehicles ECU(s) (Electronic Control unit). The ECU(s) act like the brain of a car. In the event a sensor is not reading correctly or within the set parameters, this usually brings on a warning light. Sometimes the vehicle will put itself into a Restricted Performance Mode or Limp Home Mode, which it does to protect itself against damage but allows you to drive to safety.

So, the car tells you exactly what’s wrong?

Sadly, it isn’t that simple. This is where our comprehensive equipment and expertise come in to interrogate the vehicle, through its On-Board Diagnostic port, to find the source of your fault. We have main dealer level equipment and many years’ experiences, so your vehicle is in safe hands with us!

More on Diagnostics

The sensors on your vehicle are situated from the road wheels to the engine and beyond, all of which communicate through the vehicle’s Central Area Network (CAN) bus. The CAN-Bus operates similarly to the human nervous system, whereby faults are alerted to it, then reported back to the brain (in a vehicle’s case the ECUs). You can see this explained in the video.

Simply the best garage I have ever known.

Simply the best garage I have ever known. Friendly, super helpful and honest. Great staff. Can’t praise them enough. Also very good for second hand cars. JB – 2022

Excellent service for a very good price…

“Excellent service for a very good price, I moved into the area 18 months ago and decided to use Turbo Jection as they were close to me. I have been very impressed with their professionalism and honesty and have since used them multiple times and have recommended them to anyone who needs a garage that they can trust in. I have mainly dealt with Bill and Steve and have always found them to be courteous and friendly and always willing to listen to you as a customer and explain what they have found/carried out at a level you can understand. Use these guys and rest assured that you are in very good hands!”

Fantastic service from start to finish!

“Fantastic service from start to finish. We’d been having our car serviced for a few years elsewhere (other side of the country!) and of late not 100% convinced of quality, so decided to some ‘home’ and have Bill and his team here look at the car. We needed a fair amount done to the car over a short period of time but they did everything and more of what was asked, a proper fantastic job done. It’s not the cheapest around, but you’re pay for quality and experience. A truly honest, trustworthy and local business.”

Nice people… Down right honest…

“Nice people doing their best to sort out your car in their best of abilities. Down right honest because they know what is a hard earned money is. Always felt welcome here which is a bit unusual from my previous experiences from other garages. Bill is a good and efficient mechanic.”
