The Opus IVS 360 live diagnostic repair guidance support service is designed to assist garage technicians in the delivery of efficient diagnosis and repair of today’s most complex vehicles.
IVS 360 is backed by more 100 OE-certified master technicians who deliver live diagnostic repair guidance daily to garage technicians.
“Our users simply log in and send a support request directly from their DrivePro device. Our master technicians then support them with step-by-step guidance. From diagnosis to repair – we support them every step of the way”, said Karl Booth, Opus IVS head of sales for UK, Europe and Australia
A recent case saw the IVS 360 team support a garage with a Volkswagen Group car. The DPF warning light was displayed on the instrument panel cluster, along with the pre-glow warning light.
Symptoms
- DPF warning light on together with pre-glow warning light.
- Loss of power.
- Engine Management light on.
Fault codes
- P2002 (8194) Particle filter bank 1 malfunction ECM – ECM.
- P242F (9263) Particle filter maximum load exceeded ECM – ECM .
Cause
- High soot loading in the DPF.
IVS 360 repair guidance provided
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 that 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 and 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, these are the two reasons:
a. The soot loading is over 45mg. The vehicle is running in emergency operation.
b. The regeneration cut-off time of 4500 seconds has been exceeded.
c. The soot loading may not be above 45mg to carry out an emergency regeneration.
In either of the above 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 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.
Opus IVS’ patented DrivePro diagnostic device covers more than 60 vehicle brands and always comes with IVS 360, ensuring that technicians can drive down repair times with ‘right first-time’ fixes.
Karl explained: “Our 100+ strong team of IVS 360 technicians have expert brand-specific skills like you’ve never seen. Kevin Hardy for example is our Mercedes Master Technician. He started in the motor trade in 1973 as an apprentice with Chrysler.
”With 50 years of experience under his belt, he, along with his colleagues have a lifetime of knowledge to share with IVS 360 users”.

Opus IVS will be showcasing their time saving vehicle repair solutions at their next Technical Open Evening at the RMI Academy in Runcorn, 19 April.
