First post here...feeling a bit newbie!

I live in Belgium and I own two Alpinas (2006 D3 and 2015 D4).

The D3 needs a change of the dpf filter (170000 km).

According to my garage, I'd need ~2000 € for replacing it.

Now, the car is not new and I'm planning to sell it soon (I'll most likely post images here), but I was wondering if I really need to change the dpf filter, or I can have it cleaned (mechanically, not by chemicals). Cleaning is cheaper, but I'm afraid it won't solve the issue.

Any advice or past experiences?

Thank you in advance!

Have someone take it off and chemically clean it and then flush it. some garages also do a very high temp bake.

Then reset service indicator. 300E at the most.

From what ive read a properly reconditioned one is only a few % less efficient than a brand new one.

A forced regen is done by way of plugging in to the OBD port which is probably the £45 fee.

A clean of the DPF involves taking it off the car and cleaning which is a lot more labour intensive and hence more expensive.

BMW dealers will go straight to the - "computer says you need to replace the DPF ".

Thank you for your replies and sorry for having reacted so late!

I think I will give a try by asking for such service to nearby garages...I guess if I go with a specific request they should be able to help me and to give a quick cost estimation.

Indeed, the official BMW guys told me that the power isn't anymore what it used to be, and that the DPF filter has to be changed. Cost: 1800 €.

I normally go to official BWM garages for maintenance, keeping a record of all operations on the car itself, but this time I think I will skip.

Thank you everyone!
