Car and Van Diagnostics

Vehicle Diagnostics

Successful diagnosis and repair is dependent on several things:

  • Gathering all relevant information from the customer to understand the symptoms or nature of the fault.
  • Training to ensure sound knowledge of how the affected system works
  • Access to all of the relevant manufacturer’s technical information
  • Creating a detailed test plan to ensure a thorough diagnostic process
  • Having the correct tools and equipment to test the circuits and components
  • Having the knowledge and experience to use the tools and equipment correctly.


If any of the above are weak or missing then the correct diagnosis is unlikely and this leads to time being wasted and/or unnecessary parts being replaced, normally at the customer’s expense. Sadly this is a story we hear too often.


With regular training and constant investment in the latest diagnostic equipment Bull Lane Garage has built a strong reputation for being one of the leading most successful diagnostic specialists in Kent. This is backed up by our director and diagnostic specialist- Karl Weaver winning the Top Technician 2017 title.
