Options for DPF? Delete, replace or clean?

[karlbar2k]

OK just scanned the Scout and here are the figures so by my maths and the mythical 175ml it should be good to 175K given that its covered 143k so far

  1 hPa   Particle filter; difference pressure 152
  54451 m   Particle filter; kilometers since last regeneration 153
  2.38 l   Particle filter; fuel consumption since last regeneration 154
  0.14 l   Particle filter; oil ash volume 155
  2 hPa   Particle filter; offset for differential press. 156
  8.29 g   Particle filter; soot mass calculated 157
  -0.19 g   Particle filter; soot mass measured 158
  2844 s   Particle filter; time since last regeneration 159 

 

But what are the real options available now?  Is cleaning now possible and is it cost effective vs replacement

 

I did find this site has a chart with peoples measurements http://forums.tdiclub.com/showthread.php?t=324067

and there is one on there at 300ml of oil ash  so did vag do different sizes of DPF??

Removal doesn't seem wise give the latest MOT checks...

 

Personally, I'd wait until it's a problem but have some money saved for a replacement or cleaning it.

 

I'm still not sure where the 175ml figure originally came from but I've not seen any maximum listed in VW/Skoda documents I've come across. As you've mentioned, there seem to be plenty well past it.

By Quite happy to get to 300k miles

If I remember correctly, for my 2.0pd scout, the maximum ash content was 30g. It may be worth trying a cleaning process - a genuine replacement DPF for my car is over £2k and talking to a few VAG specialists aftermarket isn’t reccomended.

if you go down the removal route make sure you have a friendly MOT garage first.

My pd engine Scout has 177k miles at the moment and is showing no current signs of dpf failure (Famous last words). I'll try and get a VCDS ash reading if I can prise the car off the Mrs.

I'm surprised to see a blocked dpf on a vw engine that's bolted to the turbo, I'm on 163k and as said above no signs of failure yet. 

Don't think I'd delete myslef would rather have cleaned or renew.

 

I do know a friend that whips off the heated o2 sensor on top of dpf and frequently cleans his dpf along with the turbo (as it's alongside) with Mr. Muscle, leaves for few hours, screws heated sensor back in, starts 1st turn. 

Not saying it works myself but he's had no problems with his 150k golf.

The DPF delete. It occurred to me that you could make a passage way (with a long bar) through the substrate and then just replace it - Mr MOT man would not see the internal mod. And if you don't make the passage too wide then the sense lines fore and aft of the substrate would still see some pressure differential and hence the ECU would be happy and not chuck out fault codes etc? Has this approach been tried before?
