Understanding Engine Diagnostic Codes

What Are Fault Codes?

Engine diagnostic codes (DTCs - Diagnostic Trouble Codes) are alphanumeric codes that help identify specific problems:

  • P-codes: Powertrain (engine and transmission)
  • B-codes: Body systems (lighting, heating, etc.)
  • C-codes: Chassis systems (brakes, suspension)
  • U-codes: Network communication codes

When to Get Diagnostics

Book a diagnostic test if you notice warning lights, poor performance, unusual noises, starting problems, or failed MOT emissions. Early diagnosis can prevent minor issues becoming major repairs.

Regular diagnostic checks can also help maintain your vehicle's performance and identify potential problems before they leave you stranded.

Frequently Asked Questions About Engine Diagnostics

How long does an engine diagnostic take?

Most basic diagnostic scans take 30-60 minutes. However, complex problems may require additional testing time. We'll provide you with an estimated completion time based on your specific symptoms.

What happens if no fault codes are found?

Sometimes intermittent problems don't store permanent codes. We can perform additional tests including live data monitoring and component testing to identify issues that don't generate codes.

Can you clear fault codes after diagnosis?

Yes, we can clear fault codes after diagnosis and repair. However, we recommend fixing the underlying problem first, as codes will return if the issue isn't resolved.

Do I need diagnostics if my check engine light is on?

Yes, a check engine light indicates your vehicle's computer has detected a problem. Diagnostics will identify the specific issue and help determine if it's safe to continue driving or needs immediate attention.

Can diagnostics identify all car problems?

Diagnostics can identify most electronic and engine-related problems. However, some mechanical issues may require physical inspection. We combine diagnostic data with our mechanical expertise for comprehensive problem-solving.

Will diagnostic costs be deducted from repair work?

If you proceed with recommended repairs based on our diagnostic findings, we often deduct the diagnostic fee from the total repair cost. We'll explain this when providing your repair quote.
