Just wondering if anyone knows what the mechanical differences are between the 400 and the 450?
 
as above, @mmi totally different engine

EU5 > EU6
400Nm >450Nm
132kW > 150kW (204PS)

Yes I'd seen that doc, thanks.
On the Australian VW website you can select the 400 or 450 engine so I'm a bit confused. Mines a T6 and I presume a 400 but I can't work out the differences from that doc as it goes from the 340 straight to the 450.

ah right, look s like the Auzzies are listing thing different,

they listing them by Nm power.

so, they are ALL EU6 and bluemotion. (not the older EU5 engine)

the same 2.0ltrs engine is available in 3x power options: 340/400/450Nm (Europe lists them as BHP or PSI power) (Europe has 4x power options, 84/102/150/204PS)

so the basic difference is more power,

its a trade off for more power/torque vs fuel economy =]

TDI400
Some grunt
Boasting a bi-Turbo with up to 132kW and 400Nm of torque3, the TDI400 delivers an impressive amount of grunt. It’s even available with the latest 4Motion technology in conjunction with DSG transmissions.

Factors including but not limited to driving style, road and traffic conditions, environmental influences, vehicle condition and accessories fitted, will in practice in the real world lead to figures which generally differ from those advertised.

TDI340
Economical
With 103kW of power and 340Nm of torque3, while this turbo-engine is undoubtedly powerful, it’s also the more economical of the Transporter options.

I still think the "400" is hardwarewise the one described in the SSP 455 (T5 2010) under engine designation CFCA. In Europe that engine was installed in T6 till about 2016.

And the "450" would be in the SSP 564 engine under designation CXEB. Unfortunately neither the AUS configurator nor the brochures go down to that level details.

A kind of indication of these being "different generation engines" would be e.g. announced fuel consumption figures in the spec - significantly better for the "450". Actually the "450" being the most economical of all these! :speechless:

Anyways, the spec for the "340" above is very similar to EU5 140PS engine (not the EU6 150PS). Also the torque vs. rpm values seem to support this theory.

When using "liters/100km" - the smaller figure the better.

Anyways, happy to stand corrected on this.
 
Last time i looked (which was a while ago)the adblue engines were never released in australia as they dont have to confirm to the eu6 standard
Looking at the tech spec table it would seem
TDI340 = EU5 140
TDI400 = EU5 180
TDI450 = EU6 204
 
Mines a T6 and I presume a 400
Actually there should be a sticker under the dash which has configuration information of your van, including exact engine type+power. Look for a code like e.g. CAAC, CFCA, CXHA, CXFA, CXEB. On top of timing belt cover there also might be a sticker having three first characters of the code. As the last resort a picture of the engine would allow forum members to identify it.

Thanks for the clarification. I was hoping it was just a "tune" difference between the 2 but its looking like the differences go further. From what I can find out the 400 has an air to air IC where the 450 has a water / air IC for a start. No doubt different turbos as well.

Now I'm itching to get a 450!
 
The 400 and 450 are both bi turbo but your right about the intercooler / charge cooled
The 400 is the same engine as fitted to T5.1 vans so that’s around 2010-2015
