Exhaust regeneration - on a petrol??

[Zerouali]

As the title says. my mate stuck his car in at the local dealers to have a niggling fault fixed. It came back with a letter explaining what they've done
and the original fault remaining. It sounds like a breakdown in communication (my mate isn't the most technically minded) as the original fault wasn't
a fault at all, basically a function needed switching on

However, the dealer had the car for a day and carried out an exhaust regeneration. On a 320i. Which, as far as I'm aware, does not have a DPF fitted.
Does anyone have any idea what they might have done?

Sounds like the real reason has been lost in translation

Petrols do not have DPFs or "PPFs" yet.... but believe me it has been considered and may do in 5-10 years (NOOOOOOOO)

Functions that sound like regeneration:

Adaptions?
VANOS exhaust adaptions?
Injection corrections/adaptions?
Recoding perhaps of a particular component?

OR

REPROGRAMMING of the MAF or injectors or alike?


Regeneration in any gasoline/petrol sense doesnt sound similar to anything?

That's why I'm so confused. Just to clarify that my mate has a letter from the service team stating that the work carried out was exhaust regeneration.

I think he'll have to give them a call and ask some questions, God knows what they were up to.

Actually, come to think of it, I'd be surprised if even God can figure this one out.....

My E92 320i has had a catalytic converter regeneration* done several times by the dealer, during my 'troubles'....
Strangely, it alway scomes back with a clean exhaust pipe which then 'soots' up over the following few days.
Also, strangely, it seems to run very well for the first few days before slowly returning to it's usual cr@p self.
Go figure.


(*I've been told that all they do is drive it at a constant speed above 40mph for around 20 minutes.)

Sounds like the dealers polite way of saying "ragged the nuts off it for half an hour".
