T5 Post Icon Remap and DPF removal

I'm about to book my truck in for a remap next week and was wondering if I should get the DPF removed at the same time but was wondering wot the advantages of it being removed would be

What model do you have? the T5 1.9TDI in this country do not come with DPF fitted, its only the 2.5TDI 131 & 174 from late 2006 onwards that has the dpf systems fitted.

Removing the dpf will allow for better spool up of the turbo so more low down torque will be achieved with a custom live remap, also you will see a good increase in fuel economy as a result of the engine/exhaust not doing the regen.

Other benifits are never any DPF related issues that are common on these if you only do local driving, problems like blocked/collapsed dpf systems, cracked exhaust manifolds, blown turbos, dpf pressure sensors etc etc.

I had a customer from Bradford a month back that had spent close to 3k with dpf related problems and it was only the luck of one of the mechanics that worked in the maindealer that the customer found out about me so he didn't have to put yet another dpf system on the vehicle.

I would 100% recommend if you have a 2.5TDI 131 or 174 having the dpf system removed and also make sure it is live mapped after as a generic remap will not work with a dpf removed setup.

This is one of the things that I would love to see verified.

Talked couple of weeks ago to a vw mech and he said the smaller consumption is . Of course it does not use fuel andymore during regen, but even if longer timeline (1000km, 5000km) considered there shoulg be no savings in fuel.

Heck,even VW lists in their charts that the no-dpf versions use 0.2-0.6L MORE than DPF versions!?


So where lies the truth?! Interested to hear.

Any improvement in fuel consumption quoted on the 2007 on models will be down to improved mapping, reduced losses from ancilliaries, optimisation of manifolds/turbo and probably a lot of tyre polishing and frigging the coast down torque figures they use on the climatic chassis dyno. Stuffing a DPF in the exhaust will only increase pumping work on the engine. The amount of power required to push over half a tonne per hour of hot exhaust gas through a fine ceramic block will run into kilowatts. Removing it will add the lost power onto the net crankshaft power output and also change the combustion characteristics as not only airflow will change but the mixing of residual exhaust gas too so its best to get a remap too.

jawdropping Re: Remap and DPF removal

I read this DPF is basically a soot extraction and burning device bolted onto the back of the exhaust.?
On regeneration it pumps in a bit of fuel and sets it on fire to clean it.
Lot of energy and technology wasted on a type of carbon that will NOT hurt the planet!!!

The greenhouse effect may be a debatable topic but the long term effects on health from exposure to particulate matter is well proven.

Its just a question of whether you agree that increasing CO2 emmisions and putting up with (possible) climate change is worth reducing the risk of getting lung cancer.
