tried to use VCDS to force regenerate the DPF,, due to car every 2 weeks seems to hold the revs at 1000tpm even when I’ve blasted it down the motorway,, (60 mile round trip) it says press brake then throttle but then shows the screen above,, am I doing something wrong 🤣?? I know I should have taken a photo of the readings but I forgot think something said 90 but can’t remember 🤣🤣,,

would anyone know what the readings should be between??? Car is a 2.0l tdi VRS 2010 124k 

thanks peeps 

At 33g I think you are above safe regeneration threshold, so it will be blocked.

Check what your soot reading are, as I am assuming that "33" = Soot value.

 

EDIT: This is an older document, but could give you an idea of the rough cutoff points for soot

Have a look in the security access if there is 27971 (from memory) regeneration whilst standing and enter the value, then go back to basic settings.

That number does ring a bell I pretty sure I did that 

this is what comes up,, tried typing soot but nothing shows in box 

Sometimes they change the wording of things between ECU'S

 

That oil Ash volume might be at the limits 🤔 maybe @Crasher can confirm or has another idea.

 

Also, if the soot is low, the car won't allow a static regeneration iirc.

Cheers boss,, 

If it is high would a good drive help or is it close to been fubar 🤞🏻🤣

That Ash level is high for most, the figures I am seeing vary so much and as you say the wording. I did a service regen on a €Q3 on Friday and my business partner came to see how I was doing and couldn’t understand the Soot loading measured was 30% and the calculated much lower and was more puzzled when I told him at the end it will be 3% and minus 10 respectively, think that’s the right way around. I have been working on a rare one, a Golf 5 PDTDI 170 BMN that actually has its DPF still. We sent the DPF away and it came back with a good heath report. I reinstalled (yes I did some real work!) and there is only a regen when driving; we did two others last week a Scirocco and an A6 Ultra and they are all different, it is difficult keeping track of all the different systems we have to do.

When you open up VCDS, sometime if you hover over a target, it might say what the "limit" is.

 

ODIS Service would probably give you a better indication of how far through the life it is, or maybe just say that it's "ok"

 

There will also be static regeneration rules, like engine temperature and more than 1/4 tank of fuel, any of these factors will kick out a regeneration in my limited experience.

Soot = carbon

Cheers guys really appreciate all the advice, I suppose baring taking it for a drive again,,my only options are DPF delete or a new one at about £1000 or find out if somewhere can clean it out (with a Jack hammer 🤣)

did find this and used it to have an idea what to do but it said power consumers on lights heater window heaters seat (don’t have em) would it be because I never put any of these on maybe ??? 

Yes that's basically the list, but your current soot levels are too low to clean anything, this is main reason for the refused static regen.

 

Your 90g (sometimes measured in ml) of oil ash, seems to be at the limit of what the exhaust can hold.

If this was my car, I would be tempted to reset the exhaust in VCDS where you tell it you fitted a new exhaust.

 

Have you tried hovering mouse over the oil ash to see if they offer up the limits?

No mate but I will try when I get home 😢,, can I put hetty hoover on the end and suck it out 🤣🤣

Ah, found this in my DPF document, my limit is 80g oil ash mass

When you get home, pull up this value on your VCDS.

 

As mentioned before, might be an idea to tell it you have a new exhaust and see how the car behaves after, it's not like the DPF filter stops working (as long as the soot keeps burning off, I would do this)

If it regens too frequently, or becomes blocked in limp mode, then you need to get it washed out or replaced (eeek!)

Nice to get oil ash volume and mass on the same screen, enabling conversion between the two numbers. 👍

Oil ash volume (litres) = oil ash mass (g) /431 from those two numbers.

My regen light has never come on but every 2 weeks the revs hold at 1000 rpm and if I don’t take it for a quick 20 mile spin it can be in for a couple of days then it stops. 
never had it in limp mode neither 

 

if I tell it it’s new how would I go about doing that ??? Can it be done through VCDS 

Given your regeneration light hasn't come on for limp mode, you're probably OK.  The car knows oil Ash levels and will be adjusting regeneration frequency I suspect to more regular timing.

 

Yes you can reset exhaust with VCDS, but not sure where it is off top of head, an adaption I think.  If you take a look about, you'll find it.

It will also do this if you don't use the car for a few days and you have a tired battery suffering with self discharge.

Hmmmm ??

battery ??? Mine does occasionally ping from the dash and I don’t know why ?? Never had an issue with it not starting? But my dials do sweep every time I start it,, remember with my ford if it did it I was a battery issue 

Needle (called staging iirc) is something that is enabled in software, so potentially a red herring.

 

Better to take a multimeter reading of battery after it has rested for 2hrs after driving.

Be nice if you can confirm in your car what the oil ass mass/volume limit is compared to your readings (curiousity is killing the cat here!)

Then you can set about maybe resetting this in the car to fool it, and see how it performs after this change.

Well came home did a bit of shopping with the other half and then thought I’d go get the laptop,, plugged in turned it on  yes you’ve guessed it my lad has flattened the battery and not bothered to charge it back up 🙄🤣,, it’s on charge ready for tomorrow 👍🏻

Its called "indicator celebration" on my VCDS!

 

They must employ a huge department of people to make up random terms and units which bear no resemblance to anything in the real world.

 

Even the times & dates of the fault codes are gibberish, 06-47- 2053 at 29.63 was my last one 🥴

 

When I have tried looking for oil ash mass I have to look through thousands of variables, many duplicating each others description, 99% of them have no values so are probably for a different vehicle, I was very late to learn there is a search function but its of no use when they wont call a spade a spade.
