Five Top Tips For Fault-Finding - Tip 3

By Damien Coleman

Prior to starting a repair, you should research all relevant data relating to the task. An example of this is investigating which special functions and procedures need to be executed after a repair is carried out.

Many components need to be ‘adapted’ to the vehicle after replacement, and an example of this is during Diesel Particle Filter (DPF) regeneration.

Certain parameters within the control module need to be reset but failure to carry out this procedure will result in the regeneration code remaining stored and the warning light still being illuminated even if the regeneration was successful.

  • The blue box is the command to regenerate the DPF filter
  • The green box is the data relating to the soot loading of the DPF
  • The red box indicates the rests which must be carried out post regeneration
  • The vehicle shown is a 2010 Opel Insignia 2.0L common rail diesel injection (LBS engine code)
