hi,did my dpf readings today off my a5 tdi,can you guys tell me how good they are,there is before and after..........i checked before i went on motorway today,and again when i came back..........

before: particle filter:eek:il ash volume 0.07 l
soot mass calculated 17.40g
soot mass measured 7.66g

after: particle filter:eek:il ash volume 0.01 l
soot mass calculated 8.99g
soot mass measured 1.11g

58,000 miles on AUDI A5



Also i need to check these reading on a golf mk6 tdi 54,000 MILES ON GOLF.

particle filter:eek:il ash volume 21.0127055g
soot mass calculated 18.82g

time of last regeneration 48551.90 s

is the oil volume of 21 too high..........if so why and what can i do to reduce it?
also im not understanding when the last regen was done?
