Hello,

 

Recently I started noticing more regens, mostly due to not driving too much on the highway.

 

I checked with VCDS, but can't make heads or tails of these readings.

Sorry for low quality pics.

 

I drive each week on the highway at 3k+ rpm, and it seems to help, but daily I drive 10km in the city, and almost every week I get regen cycles starting in the city.

 

Even after a long drive 200+ km, when I park, it still wants to spend another 20 minutes finishing a cycle.

 

Is my DPF full?

I dont have a max volume ID, or I am not looking in the right place...

 

I did throw a bottle of Metabond DPFCC today, but silly me forgot to take a reading before.

 

Since september, I am constantly using Metabond Megasel on each refil, but in december and january I stopped and then I got the most regens.

 

Few weeks ago I went on the highway 50km with 4500 constant rpm, but did not seem to do awfully much 

 

The car has 467775km on the clock, and I am not experiencing any performance issues.

 

My engine code is CEGA and unfortunately VAG dpf lite does not support it.

 

Any help would be apreciated.

How many km has the car done?

 

A lot have said 250ml ash volume = full DPF.

Its getting close to 470.000km

Idk about the oil ash volume, so far it seems to be a static value in VCDS, never seen it change, but the other two do change and I need to have the spec above 36g to trigger an active regen manually, the ECU will not let me otherwise, and I've never been able to catch it at that high value.

 

Since this started after I stopped adding additives, I started again.

In addition to Metabond Megasel, I've thrown a bottle of DPFCC, and it worked...

 

I've refilled 4 or 5 times since then, and I've allways added 4-5ml of additives per 10L of premium diesel.

 

Still smokes a bit when cold starting, but nothing excessive, and especially when its cold outside.

A bit of moderate smoking when the active regen is close to finishing, but only did it once so far, after approx 600km, in the middle of a trip.

 

I've also felt a slight increase in power, as it started screching its wheels when flooring it hard from stop.

Noticed this in an intersection, I still have winter tires and the road was dry, and I have really grippy tires.

 

I guess short hops and cold weather did a number on my dpf, but it still says 300ml, even when the other values are 5mg for spec and 0 for calc.

 

I have no idea how old the DPF is, need to find out.

 

Might also been some bad fuel batch as I refilled in that period from the same station.

 

Once I had an injector issues every time when filling from OMV, but now I am using their subsidiaries, Petrom, never had issues with them before, and the engine always had some spank in it with their fuel, even when I was not using extra additives, compared with OMV premium diesel which I always felt it made my engine run smoother, quieter, but also lazy when going from stop.
