I did a forced regen a while back, I did something like this video, then drove up the motorway for 5-10 minutes

multumesc din suflet . Nu... chiar nu vreau sa fac asa ceva și sper sa nu am probleme.
Intrebarea e pusa de un amic " mecanic " care doreste sa cumpere o astfel de interfata .
Vrea sa i arat unde trebuie intrat ( sa se convinga ca e ceia ce ii trebuie lui)
Eu vreau sa l conving sa renunte la Pc.

Hello In my modest opinion and from the experience in my workshop (VW recommends not to carry out this intervention manually, unless there is a failure in the automatic regeneration system of the ECU), the regeneration of the DPF particle filter should not be forced, FPD, etc. It can cause a lot of problems later and even cause a fire in the car. A greeting. my vw mechanic friend used to say they did forced regens weekly, some mechs used to do it in the workshop, some used to do it on the road, he said there was never any problems, he didn’t like to do them in the workshop only because all the pipes and fans they needed to connect and having to keep a eye on them, plus with going out and driving he got to get out of the garage, so I don’t know why you say don’t do them? The regens are only what the car does normally and well within tolorences of the car as their designed to do them, the reason regens are not done is normally the car doesn’t get a chance to get up to the temps/settings it needs to to burn off the soot

So when the light comes on do they replace the DPF then?

Did you read the VW link I posted? It states there if the light is on it normally only needs a regen, that’s from VW, it doesn’t say the dpf is faulty, it says try a regen,
Now when my DPF light came on I plugged it into obdeleven and it said my filter was at 56%, (just checked my figures, so yes my earlier 40% was wrong) I did a rolling regen and the temps shot up quickly while driving (still had obdeleven running on live data) drove for about 10 minutes in sport) and it went off, rechecked the level and it was just below 10%, I did take the car for a 10 minute drive before I did the manual regen, but the light didn’t go off so I guess one or more of the automatic regen parameters wasn’t right,

VAG DISESEL PARTICULATE FILTERS

Diesel Particulate Filter (DPF)
Detailed below is important information outlining the function and features of the Diesel Particulate filter which all members of your team need to be aware of.
Diesel particulate filters are becoming more commonplace on diesel engines, particularly sizes 2.0L upwards. This is in order to reduce the exhaust emissions as required by European legislation.
The prime reason for a DPF is to reduce particulate matter entering the atmosphere. Particulate matter is found in the form of soot, which is produced during diesel combustion. The DPF traps most of the soot which would normally travel down the exhaust and into the atmosphere. The DPF can hold a certain amount of soot, but not a huge quantity and therefore it needs to go through a process called ‘regeneration’ in order to clear the soot loading. When the soot goes through a ‘regeneration’ process it will be converted to a much smaller amount of ash. The ash is non-removable. There are two types of ‘regeneration’, passive and active.
During long motorway journeys, passive regeneration will occur. This needs no intervention from the engine control unit. Due to the raised exhaust temperatures on a long journey (temperatures between 350 and 500°C), the procedure occurs slowly and continuously across the catalytic-coated (with platinum) DPF. The catalytic-coated DPF is situated close to the Engine, therefore the exhaust gas temperature is high enough (500°C) to ignite the soot particles. Due to this soot is burned-off and is converted into a smaller amount of ash.
Active ‘regeneration’ is when the ECU intervenes when the soot loading in the DPF is calculated to be 45%. The procedure lasts for about 5 – 10 minutes. Specific measures are taken by the ECU to raise the engine exhaust temperature to above 600°C, these include switching off the exhaust gas recirculation and increasing the fuel injection period to include a small injection after the main injection. The soot particles are oxidised at this temperature.
The ECU will trigger a regeneration process, if for some reason this is aborted, ie. customer slows down, stops etc, the process will be resumed when regeneration conditions are once again met, above 60km/h (38mph). This will continue for 15 minutes.
If after 2 attempts of 15 minutes, a successful regeneration has not been possible, the loading will increase. At 50% soot loading, the ECU will continue to maintain maximum exhaust temperatures of 600°C to 650°C to cause a regeneration process. The system will try to run a regeneration process for 15 minutes. If unsuccessful, the system will repeat this process for a further 15 minutes, if still unsuccessful, the DPF light on the driver display panel will then be lit.
The owners handbook states, the DPF symbol lights up to indicate that the diesel particulate filter has become obstructed with soot due to frequent short trips. When the warning lamp comes on, the driver should drive at a constant speed of at least 60 km/h for about 10 minutes. As a result of the increase in temperature the soot in the filter will be burned off. If the DPF symbol does not go out, the driver should contact an authorised Volkswagen repairer and have the fault rectified.
At 55% soot loading the DPF light is lit on driver display panel. At this point the customer should follow the advice in the handbook. If they ignore this information and continue driving the vehicle until the soot loading reaches 75% without successful regeneration, additional warning lamps will light up. At this point the customer will also be complaining of lack of power, etc.
At 75%, regeneration is still possible with the use of the VAS tester. Only when the loading is above 95%, is it necessary to replace the DPF unit.
Operating Status System Response
45% DPF Load Level 1 Normal Regeneration
50% DPF Load Level 2 Regeneration at maximum exhaust temperatures
55% DPF Load DPF lamp Regeneration from 60 km/h onwards ("See operating manual")
75% DPF Load DPF, SYS and MI lamp Torque limitation, EGR deactivation,
Regeneration via VAG tester only 95% DPF Load Replace the DPF Unit
The Warranty department has confirmed that if there is no fault on the vehicle and DPF regeneration has been unsuccessful due to the customers driving style and the customers failure to comply with the instructions in the handbook, DPF replacement will not be paid for by warranty.

A mea mașina golf 7 rline.
2.0 tdi 150
An 2016 E6
162000km.
Problema : face regenerării foarte dese.
În aplicația obdeleven , unde pot vedea regenerării ratate ?
Pe vechiul vagcom arata de cate ori mașina a ratat regenerarea Face foarte des 100000-100000km

The car fails regen for a few different reasons, like if you slow down, turn engine off, temperature drops or fuel level drops low then it will try another regen in 10-15 minutes, on some mk7 golfs they can do a regen every 200-300 miles

Chiar dacă merg cu Mașina un drum de 300-400 km Ia respecta acest ciclu de regenerare 100 maxim 120 km Eu încerc sa las motorul pornit chiar și în oraș când vad ca stat turat . Ma gandesc sa nu am un soft aiurea dieselgate.. E setata sa regenereze in 100-120km

Maybe not leave your engine running in the city, it won’t get up to temperature there, it’s designed to get up to temperature on motorways and longer journeys (to burn off the soot naturally, and not need a regen) also make sure you have a good quality oil and it’s changed regularly

Mulțumesc mult de răspunsurile dumneavoastră . dacă merg doar exterior tot in intervalul 100-120km se face regenerarea. Uleiul îl schimb la maxim 10000km. Castrol dpf ( de la magazine de piese auto) nu din Reprezentanta. Mașina e cumpărată la mana a 2 a. E posibil sa am ceva modificări la softul mașini? Se poate verifica dacă sau modificat parametri ?

That’s telling me you car hasn’t had a regen in 124k so maybe the regents are failing to finish, first I’d probably try a forced regen like in the video above, make sure engine is nice and warm and you got enough fuel, then start regen, drive up motorway for 10 minutes like the manual states then turn round and drive back, so you know it’s done, (maybe keep obdeleven running showing temperatures) then see what happens after that, but 38g is well in the tollerences all be it a little high (but I don’t know where you last drove the car) also recheck the soot level when you get back

ibb.co/MRnBc1WAuto stătea turată la 1000 r/m Am scos-o la o plimbare de circa 30 km Am urmărit funcționarea START STOP (reactivare ) Acesta savactivat după circa 10 km Nu am făcut încă regenerare Forțată . Nu am unde cu aceasta pandemie ( corona virus 19 ) Frica mare sa fac această regenerare dar o s-o fac. Acele 38g vor scădea la o regenerare forțată? Da acei 124 de km făcuți exclusiv în oraș . Nu știu cum sa va mulțumesc pentru amabilitate
