PAS Diagnostics


Here at PAS Performance we can diagnose your vehicle if you have a engine management fault or the car is not running as it should. We always check your vehicle with our state of the art diagnostic equipment before we carry out any remapping to see if there are any underlying problems.

We only use the very best diagnostic equipment such as Snap-on Solus, Launch Diagun, Peugeot Plant & VAS PC!

Here are some examples of why your vehicle may need a Full Diagnostic Scan/Repair:


  • Before and after ECU Remapping
  • Vehicle engine management light is illuminated
  • The vehicle is just not performing as it should
  • DPF Regenerations if your DPF is Partially Blocked
  • DPF Trouble Shooting
  • Air Bag faults
  • Diagnostic Scan before purchasing your new vehicle
  • Coil Pack fault identification



It is important to note that we are not just talking about code readers, most of our work involves the use of oscilloscopes and other specialist and often in-house developed test equipment to determine the actual cause of any issues found.

Unlike regular garages who spend most of their time servicing and repairing the mechanical side of vehicles, at mobile ECO tuning we specialise in the increasingly complex computer controlled electronic systems on a very wide range of vehicles. We also have the skills and specialist equipment that enables us to repair most electronics systems such as ECU’s to component level, allowing us to repair ECU’s rather than replace them.

70% of our work is for local garages and workshops who often struggle to diagnose due to lack of equipment or knowledge but with our coupled experience we can diagnose most faults within the hour. At your convenience.
