I have been checking my Octy mk3 DPF data.  I took the first reading before and active Regen finished then after one completed as left it on the drive smelling of burning rubber until the revs dropped back to normal. There are no issues with the car so just for interest. 62k on the clock. I get a an "active regen" about every 300miles or so with my typical driving which seems normal from reading the thread in the mk3 forum.  

 

1. Am I looking at the correct AdV Measuring blocks or are there any others in this group to look at? 
2. Presume Soot Mass Calculated reduced due to the active regen? 
3. Is oil ash mass ok at around 21.4g?  last service was at 58k. 

 

Thanks 

It's the soot mass calculated and measured that will reduce during regeneration. The numbers themselves don't really mean much as long as they don't get high enough to cause issues. Not sure what the various limits are on this generation but unless you get a warning light, I wouldn't worry too much.

 

The oil ash volume and oil ash mass represent the stuff that can't be burnt off. Eventually this will build up and cause the DPF to clog up and need replacing. I think VAG DPF app suggests a maximum of 80g for oil ash mass so 21.4g in 58k seems normal enough to me.

Thank you for you input much appreciated.  I'm happy with it doing its thing as it needs to and am familiar with how often it happens so i wasn't worried about what i saw. Its Always worth knowing what things are doing when they were working normally. Might log it one day to see what the temps get too. 

 

Thanks
