VAG 1.6TDI 2009: DPF Filling and Burning Issues During Extended Drives

The patient is the engine 1.6TDI design with 2009 on CR .

The car initially started the emergency mode because the throttle jammed + it did not burn out with dpf = the entry in the emergency trim (beads + dpf control).

After replacing the throttle, visiting several "tuners" everyone stated that dpf is not yet to be replaced / cut because its consumption is estimated at 1/4 1/3.

The problem is that while driving the car fills up dpf all the time until the filter panel appears on the top of the car - just go to the gas station and wait for a moment and the car burns back to 900.

You can also notice that before the control is displayed and it already has a fill, it burns at every stop.


The problem appears on the route - namely at longer sections when the indicator light is on, you can go 50, 100, 200km and you can I will not smoke (so much from driving off the car on the highway) but just pull off for a moment on the shoulder and the procedure is active and burns out. In such a situation the car surprisingly prefers a city like a highway because there is more = there is time for burning. Needless to say, the car stalls a lot because it enters the firing mode and there are other consequences of a badly functioning system. Can you check somewhere in the VCDS if the procedure is not turned off while driving?

It behaves in a nutshell as if you were switching off the cleaning procedure of the filter while driving, and only when it was stopped it switched on.

I will add that it has a VCDS diagnostic tool, changed the dampers (so that it does not blow beads), and a dpf pressure difference sensor.

Hmmm ...
Filling, injections ....
Fairy I'm not
Other parameters.

Injection one of the tuners checked and does not "fly" but if you have any other test (specific parameters) then please write how I choose it and read it.

What did this tuner still check?

Start by measuring the differential pressure.
3 gear and full load, the other thing was there any modification for you?
Power, egr?

he has checked the turbo that is ok

He still said that it can be from the throttle - (the truth is sometimes stuck but not always). after exchange, however, the same.

Auto from DSG7. No chips, egr not blinded

Is it possible to "reset" the dpf setting to factory settings?
is there any tab in vcds responsible for dpf and firing on the route? Maybe after KM?

you can make a change. so ECU will think that new (for a moment).

Up. How to do it in VCDS? Reset the indications? but will not it be cheating all the time that I have a place and will not be at all?

-----------------------------------

No other ideas suggestion? (possible measurements)
Is it removed and deleted from the dpf-a program that should technically be functional?

Hard topic. In our country, the causes of DPF problems are not repaired. It just cuts them out. I would say it in bulk. Two years ago, you would have waved your hand and the filter got rid of it. Today when the tug of war on turbodysels is getting bigger so it makes sense for as long as healthy DPF to fight. I would focus on the throttle start. However, it can be cut or loose, which causes problems with the initiation of the firing process while driving. From what I read (I do not know if all cars with DPF), the firing process starts with stopping the damper to a value of around 20% (firing optimization). EGR is also closed (completely). Maybe recharging while driving disrupts the appropriate angular position of the throttle flap and thus prevents starting firing. At the stop, the recharging is smaller, the flap adopts the appropriate angular position and the regeneration process begins. It's so for my peasant reason, that's why someone with DPF and VAG would be useful.

A friend on rossstech you will find everything.

Just type in the search engine and all the procedures you have on the table.

What is the differential pressure after all?

I managed another diagnostic program to start this problem because sometimes they write with vcds too weak and by the way I had to "fail" to burn the DPF (it's no wonder if it does not burn while driving). Of course, after burning check and dpf disappeared.

So one by one (I did not know what could help you, so there is a lot)

I am curious about the adaptation of the exhaust gas sensor: (I did not)

I will add that this is my last attempt to take up the subject - I will probably be forced to capitulate and do what others get rid of "just like a broken tooth" because I have enough money for tuners who can do what I do at home (eg burn dpf at a standstill) too thick $$$ ...). Damaged dpf-damages the rest of the car and can not be any more.

Probably that capitulation. I have seen these foty and I see that you do not know what to look at. I looked because I thought I could not see but I see other groups before and after.

Well, I do not know what I'm looking at ... Ba ... But the local tenants do not know either .

In the pictures after firing are all available readings available in the "engine".
If you tell me what to look at, then this is a detail of the screenshots.
