I have a Golf 7 estate, 2.0TDI 150CP, after 200.000 I have 41g oil ash, so I'm at 50% and the limit is 75%. (to avoid DPF destruction), ...if you drive no more than 15.000km/year mainly in the city, you will add 5-6grams of oil ash into DPF (I've been following this for 3 years).
The idea is to clean the DPF when you are at 75%, there is a special machine used for DPF cleaning. Please clean it, do not remove it..we are all living on the same planet and breath the same air!
In Romania, the cleaning cost only ~70Euros...and some extra money for disassembling /assembling.
