    Question VWwA Diesel FAQ

    Which Volkswagen models have Diesel Particulate Filters in them ?

    Polo 6R = 1.6 TDI
    Golf VI Range = 1.6TDI 2.0 TDI
    Golf GT Sport 2.0 TDI
    Jetta MY09 onwards = 2.0 TDI
    Eos = 2.0 TDI
    Passat MY09 onwards = 2.0 TDI
    Passat CC = 2.0 TDI
    Tiguan MY08 onwards = 2.0 TDI (103kW)
    Touareg MY07 onwards = 2.5 TDI, V6 TDI & V10 TDI
    Caddy MY2011 = Range
    T5 Multivan = 2.5 TDI (optional)
    T5 MY2010 onwards = Range
    Amarok = Range
    Crafter = Range

    -Caddy Range MY2011 onwards - 1.6 TDI & 2.0TDI
    -T5 Range MY2010 onwards -Range
    -Crafter - Range
    -Amarok - Range



    Whats the difference between Clean TDI, BlueTDI & BlueMotion ?

    Clean TDI http://www.vwvortex.com/artman...shtml

    This clean diesel Jetta meets the lowest emissions standards without the use of urea injection. Instead, a nitrogen oxide storage catalyst reduces NOx emissions by up to 90 percent. The engine management system in the Jetta changes operating modes periodically to treat the NOx that has been stored in the catalytic converter. A particulate filter in the exhaust system further reduces emissions.


    BlueTDI http://www.vwvortex.com/artman...shtml

    SCR is the usual international acronym for "Selective Catalytic Reduction". "Selective" refers to the fact that this catalytic converter has a very special task. Its purpose is to selectively convert the nitrogen oxide (NOx) exhaust components to nitrogen and water without generating any undesirable side products.

    The nitrogen oxides are converted utilizing a synthetically produced, water-based urea solution, e.g. AdBlue, which is stored in an auxiliary tank on the Touareg BlueTDI. The substance, consisting of 32.5 percent urea, is continuously sprayed into the exhaust stream before the SCR catalytic converter. It is metered based on the mass flow of the exhaust. Engine management ensures precise regulation, based on information from a NOx sensor located after the SCR catalytic converter.

    Atomized into a fine spray by a screen, the urea is transformed in the hot exhaust gas stream upstream of the catalytic converter. In the SCR catalytic converter this reacts with the nitrogen oxides and splits them, as described, into nitrogen and water. The water-based additive AdBlue is non-toxic, odorless and biodegradable.

    AdBlue is consumed at an average rate of about 0.1 liter per 100 kilometers. Consumption and tank size are sized so that the AdBlue supply does not need to be replenished until the next scheduled service.


    BlueMotion http://www.vwvortex.com/artman...shtml

    Engine This new engine generally distinguishes itself through modifications in the areas charge changing (turbo charger with variable turbine geometry) and optimized exhaust gas recirculation (EGR) with an improved EGR cooler and electrically powered EGR valve.

    The diesel particle filter (DPF) comes standard with the Polo BlueMotion and despite being considerably economic is very agile.

    Transmission The second technical column for saving fuel is through the power train. For its use in the Polo BlueMotion, the five gear transmission received longer translations with cruising gear characteristic that lower the rotation level. Especially the gears three to five have twelve and 24 percent longer translations. Effect: From now on, the three-cylinder TDI works in its most efficient rotation area more often and longer. These modifications in the drive train area are supported by 14” alloy wheels, especially created for the Polo BlueMotion. The wheels come standard with optimized roll resistant tires.

    Aerodynamics As a third supporting column an optimized aerodynamic helps lower the consumption. Especially the front part underwent a strong overhaul. A fluidic optimized front spoiler as well as new, except for a cross gap nearly closed radiator grille, make their way through the air stream with low air resistance (cw = 0,30, cw x A = 0,62). The aerodynamic was also improved in the rear. Here a modified heck spoiler and a roof ledge spoiler are used. All aerodynamic measures were conceptualized via calculations and test series in the wind tunnel and then transferred from the design into the components accordingly.

    Ben, can you check when the Touareg R5 got the DPI, it wasn't until '06 or '07 I think.. V6 has always had it and V10 since at least '05 and possibly always...

    According to the literature I have it was not untill MY07 that all TDI Touaregs received DPF systems.

    DPF was introduced when the price change was done pre-facelift.

    Thanks for this, good post.
    Worth noting that also Golf VI 1.6 TDI (or 77TDI) have the DPF installed in them & use common rail.
