Hi.

Dpf light is coming on more regularly. Once or twice per week amd we only do do around 150 miles per week.

When you drive car enough so light goes out does that mean dpf regen is complete?

How often should dpf regen happen?

Thanks.

The DPF thread pretty much covers this in detail. You say you do only 150 miles a week but it is how and where you drive will dictate the regens. The DPF light will come on when the DPF is saturated enough that a normal regen cant clear, you have to "force" the regen. After 13 months of having my Antara I havent had the light come on once.

Never had the light on my dash, regens take place average 500 miles plus/minus 20 miles.

Not being controversial here but I would question whether your mileage of 150 a week warrants a diesel, appreciating the antara is really only available in diesel. I think with most modern Diesel engine you would be encountering similar issues based on that mileage.

Can you provide more info- age of car, mileage?

Christ I thought I had DPF problems.
Take the car back to the dealer and demand they fix it or you will reject the car.

The light shouldn't be coming on at all in those circumstances, take it back. Might be worth reading some DPF topics on here first so you're armed with knowledge or they'll probably just fob you off!

I think you might find with this one that it is the low mileage and type of driving, 1k in 8 weeks isn't a lot of driving and under normal circumstances should have done 2 regens at most - What is your typical journey - distance, time and speeds?

I think you may have continuos issues if you are doing just over 100 miles a week. I would give the car a decent long run to see if that makes any difference but it might just be something you will have to live with.Edited by: JR123

150 miles per week should not present any issues with a DPF, a brand new car with 1000 miles on the clock. To suggest otherwise is just ridiculous!!

I guess we'll have to disagree on this one, the car will have done numerous stop start journeys before taking ownership, this linked to the newness of the engine and exhaust system, I would doubt it has even got hot enough.

150 miles a week is no where near enough miles for a modern Diesel engine, if it was why are some dealer making people sign waivers on the DPFs when they sell or deliver cars stating that low mileage and regular short stop start journeys can cause issues and are not covered by warranties.

I could understand the car doing an unexpected regen during the first 1000 miles but to have the light come on, on a regular basis is not right.

It doesn't matter how or where I drive mine, it still regens every 500 miles- thrash the nuts off it = 500 miles- cruise round back roads in high gears= 500 miles.

It is perfectly possible for the filter to be nearly saturated within 1k, that's why the system regens at 500, if it hasn't completed a full regen cycle then it will cause the issues.

A couple of articles which may help on the low mileage issue and stop start, town driving, maybe all manufacturers should provide something similar in the marketing literature...

Here and Here

"One important factor to bear in mind when choosing diesel is the increasing use of diesel particulate filters (DPFs). In mixed driving, these filters work fine, but if your lifestyle is mainly town-based, you should think carefully before buying a DPF-equipped car. A diet of low-speed urban motoring will clog DPF filters, and the manufacturer's suggested regimen for unclogging them doesn't always work. "Edited by: JR123

I personally don't believe that to be true JR. 150 miles a week on a new car with only 1k on the clock- that's not right IMO.

I did not sign any waivers when I ordered or received my car

I have only noticed on regen. That was at 400 and something miles, the car has done 6045 miles I do a lot of town driving then school run that's 8 miles there then 8 miles back but I try to go onto the motorway for one junction and heavy foot it

as said before I think a absent minded Korean put my car together, kidding aside something has to be done if their is hug problems with the DPF and Vauxhall should be brought up to speed (get it) on this.
I think mine must be the same as hubby's and doing the regens in the background .

Fair enough - so my question would be regardless of age of the vehicle why are regens taking place at 500 mile intervals??

The regen takes place to clean the filter and if you stop it, it tries again, from experience this is the next journey, keep stopping them and it's feasible to have the light on within 1k from the last one.

Based on that mileage it is less than 8k a year and unless the vast majority of this is motorway miles, it is simply no good for a diesel with a DPF.

We dont know the type of driving being done here, but if it's stop start, town driving with a bit of motorway driving, let's face it, it's likely to be on the mileage (less than 20 a day) then I personally believe this is not an issue with the car.

I specifically ask the dealer when I bought my car about the DPF, he asked what my daily commute was and I told him 30 minutes / 20 miles mainly dual carriage way driving per journey, he said that would be fine, and so far it has been.

This is a car renowned for major DPF issues from new.

The original post suggests the light has been coming on since before 1k & also suggests that it has been driven until the light goes out.

At 150 miles per week the regen has easily enough time to burn soot off- even if this is over multiple regen attempts.

The car is only 2 months old from brand spanking new.

Now, call me pessimistic, but to me, the odds stack up in it being "yet another" VX Antara with a DPF Fault!!

I'm doing about the same short trip mileage at the moment and it's just done an "invisible" regen 400 miles after the last one, I keep an eye open for anything but the 999.9 when throttle off, spot it and go for a 20 minute run straight away, it does it's regen and it's happy again.

Never had a light on.

I would add that I think it's following information and advice from this forum (spotting a standard regen) that keeps me out of trouble with my current low mileage, nothing quite so helpful from VX literature..

My husbands car is motorway 28miles and 28 back it seems to be fine , as explained mine is much less and I did not ask the garage about the DPF as my husband never had any problems, I can't understand why so many people are having issues and yet they are doing the miles ( I think) so clearly the issue occurs during the build process as the fault seems to fall with the senior that is attached to the catalytic converter , the senior and converter seems to be to far back from the engine hence the appropriate heat is not attended giving problems for the soot to be burned off at the right temp and the sensor to work at its optimum level unlike sister car the Captivia were the catalytic converter is nearer the engine and regens without being forced to.
Before anyone eats me alive for this, thought please understand I am a mere WOMEN that is demented

listening to you men mumpping your gums so this issue should be brought forward to consumer rights as the car is not fit for the purpose and faulty parts/ or parts that are unable to do their work due to poor manufacturing or poor design at the time of manufacturing other wise vauxhall should repair this problem without cost to the consumer, if you get what I mean

TisMe see when the throttle is off or your foot is off the excellerater and you get 999.9 thingy I thought you were just coasting I thought the sign of a regen is when you see the miles thing go down to 7.9,10 although you are doing more than that.
