I wonder why it is that any new Octavia ordered now with the 150 ps diesel engine will not have Adblue, but the Audi Q6 which has the same engine comes with Adblue.

At a guess they run differing dpf systems

I think as of September all new diesel need to be fitted with adblue ( not a 100% share )

They won't need to be fitted with adblue and an SCR from September, it is just the Euro 6 regulations which manufacturers will have to comply with, how they do so is up to them.

All new cars, diesel or otherwise, need to be EU6 from September. Not all enginess need Adblue to be EU6 compliant.

Is the September the date for manufacturing engines or the car?  I expect that some customers purchasing cars beyond September will have Euro 5 engines.

 

I remember working for a diesel engine manufacturer (who shall remain nameless) when it was about to switch from Euro 2 to Euro 3, and they produced thousands of extra engines for its customers just before the change over dates. 

This explains it very well.....

This is the difference between Euro 6 and Road Fund Tax / BIK brackets.  All cars require Euro 6, however, manufacturers will obviously want to get their cars into the lower tax brackets, especially for business users.  I would assume that the Audi is heavier and/or greater drag (aerodynamic - 4x4 body? and parasitic - Quattro?) than the Octavia and thus uses more fuel; obviously the more fuel you burn, the greater the quantity of emissions are produced.  In order for both cars to achieve the same level of emissions, the heavier car will need greater emissions reduction, and thus Ad Blue as well as EGR. 

 

I expect that although both cars have the same power output, the Audi fuel consumption figures will not be as good as the Octavia.

I remember posting this in another thread.

 

You will note that this article states that all new models produced from Sep 15, not all new cars produced from Sep 15.  i.e. the Octavia could continue using the Euro 5 engine after Sep 15.

Strange the the latest Yetis have the Euro 6 150 with SCR, and Octavias are still using the older engines.

Octavias should all be EU6 according to the new brochure........(tongue in cheek)

All Octavias built after 24 May (build week 22) have EU6 engines. I would assume the same is true for all VAG models.

I've been told the EU6 engines in the Octavia don't use Ad Blue

My scout is eu6 without adblue

So are the euro6 the EA288 derv lumps then ?

1) O3 diesel engines are and have always been EA288 (1.6 and 2.0).

2) Since MY16, all O3 are Euro 6 (some petrol i.e. 1.8 and 2.0 were euro 6 already before)

3) O3 diesel do not need Adblue to be Euro6

4) whether they need specific SW or not, I don't know.

 

Other cars (e.g. S3, A4, Passat 8) have SCR with the same EA288 engine.

 

I'd say the 2.0 TDI on the Yeti is the EA189, even with SCR; this one, I'm not sure. I'm quite sure it was EA189 before Euro 6.

.

Because the Octavia is based on the Golf, so one of VAGs lighter platforms...also fairly aerodynamic the motors are able to meet EU NOx legislation in this chassis without SCR tech.

Also SCR is added to bring certain vehicles into certain CO2 bandings, which they wouldnt be capable of without SCR....hence why some new A4's, Yeti's, B8 Passats and others utilise SCR.

The EU6 150 SCR Yeti runs an EA288 motor....whilst its not on an MQB platform its been adapted to use MQB powerplants and MIB2 infotainment as have other vehicles.

This is exactly correct. Each time emissions standards are tightened, there is possibility for manufacturers to pre-produce a massive number of engines under the old standards, which can then be fitted to vehicles after the new legislation has come in to force. There are also rules that allow a proportion vehicles (based on a calculation of vehicle sales in previous years), to still be sold after the new legislation cuts in.

 

Some of the advice on other "should I reject my car" threads along the lines of, "don't worry your car will definitely be built with a Euro6 engine" is not really helpful. Me? I wouldn't accept any VAG diesel car delivery at the moment.

It has a LeanNOx system, which stores the NOx and then uses a fuel rich burn to create more CO in the exhaust, which then reduces the NOx to N and CO2.

 

There are full details online if you google.

The bigger cars have AdBlu, because they'd need so many regen cycles on a LeanNOx that the fuel economy would plumet or they just need the SCR system.

I think using Adblue is taking the pee myself. (Think about it!)
