IVS 360

Providing workshops globally with “the ultimate diagnostic support solution”

Opus IVS says IVS 360 is an invaluable diagnostic support resource uniquely designed to empower technicians to repair vehicles with confidence. Through its dedicated team of OEM-Trained Master Technicians, Opus IVS provides brand-specific diagnostic support to technicians and workshop owners all over the world.
Opus IVS explain its experts remotely access vehicle communication systems in real-time to diagnose, program and calibrate vehicles; eliminating uncertainty and giving workshops the confidence to get the most complex vehicles back on the road safely and fast. 
Customers can quickly and easily request support from the IVS 360 team directly from their DrivePro device. Following is an example of a customer support request and guidance provided by IVS 360 VAG OEM-Trained Master Technicians.
Make: VAG (all VAG common rail diesel engines)
Issue: DPF warning light on together with pre-glow warning light; loss of power; and engine Management light on.
Fault codes presented: P2002 (8194) – Particle filter bank 1 malfunction ECM – ECM; and P242F (9263) – Particle filter maximum load exceeded ECM – ECM.
Cause: High soot loading in the Diesel Particulate Filter (DPF).

The Fix:

  1. Read the fault memory of engine ECM.
  2. If no fault is logged and only the DPF light is on, then the vehicle needs DPF regeneration.
    a. The DPF light does not signify a fault with the vehicle but means the vehicle has not managed to regenerate the DPF due to frequent short journeys, stop/start trips or insufficient exhaust gas flow.
    b. To regenerate the DPF, change to a driving profile as described in the owner’s manual.
  3. If a fault has been logged in the ECU, action the fault, and carry out an emergency DPF regeneration
  4. Inspect the intake and boost system for leaks (including all the hoses and pipe work).
  5. Read out the live data for the DPF pressure and temperatures with the ignition on and at idle, the engine must be above 80°C. DPF pressure should read:
    • Ignition on – 0 mbar +/- 1.5 mbar (if outside these specs, then the fault should be a defective pressure sensor or wiring defect).
    • Engine idling – 10 mbar +/- 5 mbar (below would require checking the DPF is intact; over would suggest a partially blocked DPF).
  6. Check if all the warning lights for DPF, pre-glow and engine management are on. If they are all on, possible reasons include: the soot loading is over 45mg and the vehicle is running in emergency operation; the regeneration cut-off time of 4500 seconds has been exceeded; or the soot loading may not be above 45mg to carry out an emergency regeneration. In any of these cases, an emergency DPF regeneration would be required. Please note – the engine control module will not allow a regeneration if the soot loading is over 45mg. However, a professional clean and resetting of the DPF learnt values may suffice.
  7. Inspect other components in the exhaust system before you replace the DPF as it may not be necessary to do this. Inspection of the following components would be required:
    • G450 – Exhaust gas pressure sensor
    • G506 / G448 – Temperature sensor before DPF
    • G507 / G235 – Temperature sensor before the turbocharger
    • G527 – Temperature sensor after the FPF
    • G70 – Air Mass meter
    • G39 – Lambda Probe
  8. If you cannot find a fault with any of the above exhaust components, rectify the DPF fault before you re-assess the soot loading of the DPF through the measuring groups.
