All,
I’m a newbie when it comes to a) Golf’s and b) this forum so as previous newbies have said, please go easy on me.
I am the proud owner of a Golf mk7 GT estate, diesel. It’s a brilliant car and I really enjoy driving it however earlier DPF horror stories have worried me somewhat. Hence, my question is around the DPF, I have done numerous searches but still somewhat puzzled by this technology. I understand the concept of the unit and the methods of clearing via active and passive regeneration but still have a few questions perhaps someone may be able to help me with.
I did two long (ish) journeys on Sunday and Wednesday evening – ones which I felt would qualify for passive regeneration to occur. The car didn’t move Thursday and yet this morning when I parked up at work the fan was on and the revs were up as if an active regeneration was occurring.
So I guess my questions are (sorry there are a few):
I have read that some people expect a regeneration every tank or so, and I have also read some people get them more often.
Appreciate your help in helping me understand this…

So I guess my questions are (sorry there are a few):
- Do active regenerations take place regardless of the condition of the DPF soot loading?
- Do active regenerations take into account passive ones or is active just time / mileage based?
- I take it high revs and fan running continuously is a sign of a active regeneration taking place?
- When an active regeneration has been interrupted (such as this morning) is it advisable to take the car for a long drive to start the regeneration (passive or active) and clear out the dpf?
- Suppose an active regeneration occurs and takes the soot loading to say 20% when interrupted. When conditions are right will the regeneration start again to take the loading to 0% or wait until it builds back to 45%?
- As per the handbook, best way to start the passive regeneration is 4th gear at a speed of 50mph or more?
I have read that some people expect a regeneration every tank or so, and I have also read some people get them more often.
