Engine Fault Finding

Engine Fault Finding

Using our dynamometer to gather live data and perform safe test drives in a laboratory environment (rather than take the risks of a breakdown or accident on the public roads) gives us a real advantage over how the average garage approaches diagnostic fault finding.

The rolling road provides a consistent unchanging set of parameters for each test with none of the variables of road test drives which can be affected by so many external variables such as other drivers, wet road surface, driver error.

We have our own in-house auto electricians and electronics laboratory meaning we can test wiring and auto electronics for faults without needing to resort to external suppliers. We offer ECU testing and repairs and bench testing for a wide range of automotive modules.

What's different with our approach?

Quite frankly we are different, indeed our mindset is different to the typical garage.
Your typical garage will start with a code scan of the fault codes and dive in changing parts, when it doesn't work, they are stumped and will probably change a few more.

Our approach is simple and effective: -

  • Step 1: Code Scan
  • Step 2: Development of a test plan which we will then follow religiously until the test plan is complete.
  • Step 3: Analyse the test plan and if necessary, test more items
  • Step 4: Prove whatever item has failed the test plan is actually broken or worn and if necessary, replace.
  • Step 5: Test then Repeat Stage 1 until faults are gone
We will undoubtedly bill more hours for diagnosing a vehicle but it’s a lot cheaper than replacing expensive parts that didn’t need changing. Considering the kinds of jobs we get in, it seems that most garages fail to do basic checks before they swap out parts, quite often making things worse.

What are the benefits?

Increased Performance

You will see a 5% to 30% increase in power with every Stage 1 Remap
