Dpf readings

Hi everyone. Recently bought a 2.0td touran from a dealer and the dpf light has been on a bout 10 times in three weeks.
Done a vcds scan and came up with the values below but i dont know what they mean. Can someone please help and tell me weather the dpf is on its way out so i know to take it back to the dealer. Many thanks
PF Load coefficient 20%
PF carbon mass 55.7
Carbon mass learned value -18.3

Think I replied to this post somewhere else in this forum. Readings are too high, as Crasher said best to get it cleaned.

Wurth do a dpf cleaner.
You spray it directly into the dpf and leave it to soak.
Then burn it off with a hot run.
I used it on my Leon after i had a faulty anti shudder valve which was acting like a choke. Worked well.
