Any done a forced or manual regen on their DPF fitted car?

[cru22z]

I'm hoping someone could share a real life example instructions on how you run a forced or emergency regen
using the VCDS cable during the car running or on idle.

I read through the ros-tec already but I would prefer to hear and see how its done in real life.
So any video or picture instruction would be great.

I really dont want to get rid of my TDI Passat (MY12.5) because its a great car but frequent dpf light appearing and regular visit to dealership is becoming annoying.
So I want to buy a VCDS cable to do this regens myself. So anyone has done this or do it regularly please share your experiences and how to's with me.

My car does regens at the moment as my DPF is close to full but my car is 5.5 years old

It just runs a touch rougher, not really noticible, and then when it's done, it goes back to normal.

That fact your car is so new means there is an issue. Mine did it in it's first week, they did a forced regen and it was fine from then on.

Maybe try another dealer? This should not be your problem

If not, I can run a forced regen with my cable if need be

I have done plenty of forced regens. No big deal.

Are you sure there's not another problem with the Passat that VW haven't worked out yet. I understood that regens are carried out before the light comes on?

As Gavin said, if you need frequent forced regenarations on a new car, you should see the dealer to be sure that everything is OK. With 80,000km on the V6 Touareg I've forced regeneration only when I replaced the DPF sensor at approx 65,000km.

My bet is your pressure sensor is playing up, I am on my third one, and even though it is supposed to be fixed in the later cars, I usually find this to be the culprit. With the cable, do an auto scan on your car, and look for error codes, and paste them up here.

You should be getting approx. 800kms between regens, with some highway / 80kph driving spurts, less if all inner city. 400 or less would be a worry in a newer car like yours.

I will post up the screen shots of how to force a regen, it's dead easy, but better to find the cause, as doing to many extra regens is hell on your oil, so post up the error code scan, it will tell all.

Hi
Are you in Sydney? I live out western sydney. Is it possible to borrow your cable or even I come see you to run some diagnostics using it? The dealer don't want to see me their findings during scan.

My 1.9 TDi has had a few forced regens after about 4 years. It was fine up to that point, but driving style did change. The VCDS scans were a bit vague with what the exact error was. So we ended up replacing the sensors one by one. It has been fine since the third sensor change. When doing the forced regens, scans showed the DPF light was coming on at about 50% full, way too early, hence the sensor change.

With the warning light, you will get the DPF light. This means you should try and do a driving regen as soon as possible. as per the manual, keep the rpm about 2000 (the 80kph is not true, just drive), after running at full temp for about 10mins, it should regen and away you go. If you dont regen son enough, it goes into limp mode. You will get the engine management warning light. I have driven for a bout 1.5 weeks on this light before getting to the mechanic. It was forced regen time.

Had the car in limp mode about 4-5 times before we finally sorted it. Limp mode is a pain, as there is no turbo, so you have limited power when driving.

One final comment, they should advise all diesel buyers about DPF's. If you only ever do really short trips, and the car never warms up, you wont allow the car to do auto regens, and the DPF light will come on. You need to take the car for arun every now and then and let the car get up to temp so it can regen. Every now and then, adjust gears so that rpm stays above 2000 for 10mins to allow regen to occur.

I am a huge fan of VAG diesels and wouldnt but anything else, but I know to adjust my driving style to suit the DPF's.

800kms between regens? I have had my car since 77kms and done 82kms and dont think my car has ever done a regen?

Yes how I wish the dealership told me this. I didn't buy the car so it can change my driving style. The car should be just there when I want to go somewhere not when it a light comes up I have to go out of my way regen it or clear the light. I really like this car but having to waste my time driving just to regen or clear the light is too much unconvience for me and also danger involved. Hopefully a scan can shed some light on what it going on.

You must have one of just a few 1.9's fitted with a dpf in Australia I would think? I noticed it was an option on my Octavia. Did you buy the car new or 2nd hand?

You just aren't aware of them, but oh yes, it is doing them.

should there be a light that comes on the dash to say its doing it?
