Can adblue be retro fitted to bring octy1.6 tdi up to Eu6 spec??

Simple answer is no. EU6 1.6 TDI does without SCR (AdBlue) tech anyway.

As Pipsy said, I think the current version of the VAG 1.6 TDi is Eu6 compliant without needing an SCR system.

I'm told, but you'd need to confirm, that the EU6 Octy FWD cars use LeanNOx catalysts, which work in a very broadly similar way to a DPF. That is they store it up, then react it off to things that are less harmful.

But are they EU6 compliant given the latest breaking news in the VW diesel scandal?

Looks like it is going to rumble on ....

What does "AdBlue" add to the running costs, I take it that the DPF is retained?

You have to top up the AdBlue (diesel exhaust fluid/DEF as its also known).....the filler is either in the fuel flap or within the boot depending on the vehicle.

The tank is quite large (18 litres perhaps) and it supposed to last between services (so technically would get topped up by the dealer) but if it runs low you get a warning much like if you run low on fuel/oil....if the level gets too low the vehicle will not run at all as its reliant on the DEF to run properly.

AdBlue is quite expensive to buy similar to oil in price I believe so its yet another consumable you have to buy for the car and probably best to carry a 5 litre bottle of it around with you just in the event you get caught short.

Glad the 150 and 184 TDI's dont have it at present as can forsee it being a real pain and one reason I probably wouldnt want to buy another diesel in future years....breaking down due to running low on DEF wont be any fun.

I think its difficult to determine the difference in running costs but I think running an SCR system might work out slightly cheaper overall.

When you have a full SCR system, you can run your combustion very hot, which creates more NOx but greatly reduces particulates, thus you can have a smaller DPF.

So you will have the added cost of a bottle of Adblue every 20k km but you would (theoretically) use less fuel during regeration of the DPF.

Plus hotter temperatures should mean its easier to regenerate the DPF without adding extra unburnt fuel to the exhaust.

Is this similar to the system Volvo have run for a few years? That was a factor that put me off one and turned me to buy a passat. The refill was about every 40k and it was a few hundred quid

WHAT??

Adblue can be bought from around 60p per litre, so hardly expensive, no need to carry a bottle of it either as the car will give you a warning whilst you have loads left.

Fair comment I didnt bother looking at the price....but its another running cost and its also true that if it runs too low the engine will not start and has potential to leave you stranded....granted its really no different to running a car out of fuel but still not a wonderful prospect. Its also another part of the car to go wrong.

That said all diesels will have it soon and will just become part and parcel of living with a diesel like having a DPF has been....i suppose also DEF tech has been around a while and is pretty tried and tested.

I havent got to worry about it for the next four years at least....

If it runs out it won't restart, it will keep running if it runs out whilst driving.

Adblue is easy enough to get hold of.

Yep another fair point.....its the way they are all going but am quite glad I havent got to worry about DEF for the forseeable....

Its interesting as I have a fully funded company car....about the only thing I have to do is put screenwash and coolant in it as required. The company pays my fuel, oil etc.

I have no idea what their policy will be on AdBlue....id hope its the case it can be bought on the fuel card or at least expensed if a top up is needed.

Also is it possible to fill up the tank using the adblue pumps the lorries use, or are the pumps not compatible?

Not starting when adBlue is empty is required as otherwise you would be driving your car around with NOx emissions that would be very very high.

After all, really low emissions is why 99% of people bought a VW diesel right?

 

On trucks, you have a warning when it is very low & then a period of slow power-reduction & speed limitation.

If after a certain time when the AdBlue is completely empty the driver doesn't top up then restarting is prevented.

They have to prevent starting otherwise the drivers would never fill it up although perhaps they will relax this implementation for passenger cars.

Just think about all the taxi's running round with the MIL light on as an example.

 

I'm sure they will learn from the Audi mistake & give you at least a limited number of starts if there is a leak/problem.

 

Here in Switzerland, Adblue is available from most petrol stations in 1L & 5L bottle like screenwash.

It will be the same in the UK when its more common on diesel engines.

But in the end, most people wont need to know about it  (just like a DPF) as it will be part of the standard service to top it up.

Yes it can be purchased on a fuel card (you may need them to add it to your account if your card is diesel only though)

The truck nozzles are a pretty small diameter so I imagine they can be used on cars also.

I dare say as more cars start using it they will put pumps next to the car fuel pumps as well... it took a while for the HGV adblue pumps to become common.

You can currently buy it in 10L bottles at an inflated price (compared to via the pump)

Letting the dealer fill the adblue tank will certainly be a money making scheme for them.... just price up adblue from your dealer to see what I mean.

I imagine there will be an extra cost on the bottom of all invoices for the top up ... just like they do with screen wash (even when you fill it yourself before taking the car in for its 'service')

Of course, defeats the object of DEF if you can run around in the car without it.....I guess without the DEF solution the car runs badly, emits more NOx than a LeanNOx equipped vehicle or likely both.

I guess if the warning comes on v early (maybe giving you 1-2k miles warning) then thats absolutely fair enough.

Am I right in saying that petrol cars will in time be similarly afflicted with some sort of gasoline exhaust fluid system...so in time it wont just be diesels?

At the moment I don't know of a petrol engine with SCR system but I think some already use a LeanNoxTrap (LNT) catalyst.

As NOx emissions seem to be next on the "most wanted", if you assume the limits on these will be tightened, I guess petrol engines may well fall into the category of needing external after-treatment in the future but I think its a good few years off yet for Europe at least.

Yeah, this is true, good point!
