Hi, this is taken from Ross Tech WiKi
I would run an Autoscan to make sure there are no outstanding fault codes that would prevent it doing a re-generation, such as EGR or Injector or timing errors.
Where the text states 'Regeneraration while standing' that refers to Service Regeneration
It also states that 'this may take 30 minutes' mine took nearly 40.
You can check out quite a lot at Ross Tech, download their manual, FAQ's, Support, WiKi pages and there own Forum.
In the measuring data if you type 'partic' in the search box it will bring up the measuring blocks you need to measure the soot and ash content. You can do this without doing a regeneration.
To answer your question, yes it would reset to '0' but if there is any residual ash then obviously that might distort the reading a bit. I reset mine after a 'chemical clean' using the JML 2 stage process so not too sure what medium / long term effect resetting the value after it has been running will have.
Hope this is some help?
1.6l/2.0l R4 CR-TDI (CAN)
With the newer CR-TDI engines there are 2 different types of regenerations available depending on the actual soot mass/load. If either the calculated or measured soot mass is above 30g but below 40g you can initiate a regeneration while standing (Idle will be raised etc.), a forced regeneration while driving is also possible. Once the values are above 40g (but below the max 45g) the regeneration while standing is no longer available and the regeneration while driving is the only way.
Regeneration while Standing/Idle
Prerequisites (General):
Ignition ON
Engine ON (Idle)
Fuel Tank at least 1/4 full
Transmission in Neutral/Park
Parking Brake engaged
Coolant Temperature above 70 °C (see MVB 002.4)
Particle Filter Load below Specification (see MVB 108.2/3 -or- 241.2/3 VCDS should give the specified values)
If the Particle Filter Load is above Specification the Particle Filter needs to be replaced since the car may burn down when regenerating.
Power Consumers ON (Light, Seat Heating, Front/Rear Window Heater, Climate Control)
Engine Hood Closed
[Select]
[01 - Engine]
[Security Access - 16]
Enter the Code shown by VCDS next to Adaptation Enabling (e.g. Regeneration while Standing)
[Do It!]
[Basic Settings - 04]
Select Block for Regeneration while Standing
[Go!]
[On/Off/Next] if Basic Settings isn't automatically ON at the top of the screen.
Follow the Instructions on the Screen. This process may take up to 30 minutes.
[Done, Go Back]
Check the following groups after the regen. The Particle Filter Load should be as low as possible (close to 0 %)
[Meas. Blocks - 08]
Select Blocks 099 and 108 at once.
[Go!]
MVB 099.2: Exhaust Gas Temperature before Turbo Charger
MVB 099.3: Exhaust Gas Temperature before Particle Filter
MVB 099.4: Exhaust Gas Temperature after Particle Filter
MVB 108.2: Particle Filter Soot Mass (calculated) Alternate group 241.2 if 108 is blank
MVB 108.3: Particle Filter Soot Mass (measured) Alternate group 241.3 if 108 is blank
[Done, Go Back]
