Kodiaq RS DPF Regeneration

Featured Replies

Hi there, 

I am considering wether to buy the Kodiaq Sportline or RS model.

I like that the Sportline is a petrol and is supposedly easier to maintain as the engine does not have a DPF.

But I would prefer driving the RS as it has a more firm and "agressive" drive to as it is a twin turbo diesel, you also have the original benefits of a diesel...

- The great fuel economy.

- The power of a diesel.

- Cheaper fuel.

I don't mind the higher cost of the RS but just wondering, if the DPF would be an issue for my daily driving routine.

I will be doing 10-30min drives in light traffic taking my kids to their lessons and classes. And only occasionally (every few weeks) on the motorway for about an hour.

I heard a few things like using the OBD port to track the DPF status or forcing a regen but I'm not too great at cars so just need sombody's help.

Not too keen on doing pointless freeway drives as my schedule is already busy as a bee. :)

Would my use case not be suited well for a DPF fitted?

Thanks, 

Tim :)

  • Makes me wonder why he got the RS and not the Sportline petrol. Plus with a petrol, he could straight-pipe the exhaust then stop complaining about his 7 row diesel SUV not having enough 'bark'

  • I am in Sydney.

  • Best I ever got on a long trip on 18" winter tyres was 6,5 l/100 km (44 ish MPG). Usually between 38 (extra urban) to 30 (urban) MPG (7,5 - 9,5 l/100 km).

A 30 mins drive will not be an issue, 10 mins drives however are far from ideal... the car will not even be up to full temperature by then.

 

Check that the SportLine doesn’t use a GPF as they are on at least some of the newish petrols. 

@Tim123

Welcome to the forum.

?

What country are you in? 

Just asking to get some idea of what sort of weather / temperatures the 10-30 minute journey might be done in.

I believe the Sportline does have a GPF/PPF but according to a forum it is fine as petrol engines run at higher temps and it will be able to burn the soot with normal driving.

Yes all petrol engines run at a higher temperature earlier as they are less thermally efficient. 
Not sure if a 10 min drive would cause issues on a petrol either as a regen on a DPF would take that long to do, so (I am guessing) a GPF would take a similar time, so potentially you could be interrupting the regen on these shorter trips.

 

@Tim123

We need a year or 3 until we find out if the GPF (OPF) that VW Group / Skoda went with will be trouble free and cheap when replacement time comes.

VW like the customers to do the 'real world testing.'

Do you think an RS would be ok? My 10min drives are only occasional and almost every second day I do 20-30min drives.

A TDi will take a good 15 mins to fully warm up (heat will be coming out of the heater after 5 mins).
My wife had a TDi Yeti and only commuted around 20 mins each way and never had a DPF issue in the 4 years she had it.

 

 

@Tim123

Is Australia getting the Kodiaq vRS TDI as they are are being discontinued elsewhere globally because Australia are lax on emissions?

 

What is the Petrol Engine offered in Australia and would it not be more economic for your needs yet have enough power?

Does your current Superb have a DPF?

Not too sure but

Im pretty sure the vRS is not being discontinued and they say Australia is pretty loose on emissions

Yes my Superb has a DPF.

 

I do get regens but never had the light on the dash or any problems in 63K miles.

what is your duration of drives on a daily basis?

I all and happy new year 2021

i have Kodiaq VRS for almost a year and driving 10-20 min a daily without any problems

twice a week I do long drive and enjoy it so much ! Go for VRS ;-)

- yes in UK as well in Czech Republic Skoda production of VRS with bi turbo TDI is no longer available to order , only what is left in main dealer stocks ( and dealerships) .

- enjoy driving VRS , it’s great fun !

what is considered a "long" drive?

Will it be a new car or used car? How long do you intend to keep the car for? And if used how old is it and what's the mileage?

I used to do a 37 mile commute 10 times a week, this then dropped to 15 miles twice a week and now 25 miles twice a week (hence why I’m selling the car).

 

I still however don’t get issues or the DPF light on the dash, no doubt this is largely due to the roads which are 50% dual carriageway / motorway or empty country lanes, I am rarely sat in traffic.


Yes, I have interrupted the regen on many occasions (the fans are still going full speed when you turn off) but without exception the next time I stop the car it isn’t doing a regen anymore. 

Once again, modern VW diesels do not have to achieve normal working temperature to start DPF regeneration. Once soot level reaches critical measure, DPF starts the regeneration no mater the engine temperature is. It takes some minutes though to get DPF temperature high enough (abot 580 centidegrees) to start the process.

 

I did 390 000 km on my Superb II with no DPF issues and current RS has done 165 000 km. I do usually long trips, but some weeks I only drive to office and back (7 km one trip).

@linni @Tim123 mentions the great economy of a diesel and the cheaper cost of it in Australia.

?

What is the actual economy of the vRS doing short trips?

Best I ever got on a long trip on 18" winter tyres was 6,5 l/100 km (44 ish MPG).

Usually between 38 (extra urban) to 30 (urban) MPG (7,5 - 9,5 l/100 km).

So the OP will might be interested in what can the car get on the OEM wheels and tyres in and around Sydney and its weather conditions.

Even if there is no difference in economy, using avg prices in Sydney at the current time, ( and convering to GBP so we in the UK can have an understanding ) petrol works out at 75p per litre where as diesel works out at 65p per litre. So that's a saving straight away.

I don't mind the higher cost of the RS

Tim :)

 

But what I don't get is that if someone isn't bothered about the rather substantial difference in price between a vRS and Sportline, then why would 10p / litre difference in fuel price matter?

 

I've never understood that when people ponder the economics of running a car. And that's before we even mention the extra insurance and depreciation costings of the vRS

 

Bottom line is, if anyone is considering both vehicles, then the difference in fuel cost shouldn't be a factor in the decision process.

 

And if it's a brand new car the OP is considering, then the DPF worries should be a concern for the 2nd owner when they buy the car.

 

Sportline, vRS, petrol, diesel ?  If it's a new car then my advice would be just buy whatever you want.

The Euro 6d and newer  TDI's with DPF's & SCR can be an issue when people are doing regular short journeys and occasional long journeys.

 

That is different from regular long journeys and occasional short in just how many regens are or may be occurring.

The regens happening regularly with the town / city short journey commuter can use addition fuel so reducing the economy just doing regens.

 

The OP will be the one that knows if they are buying a vehicle as a keeper and will have it longer than the Manufacturers Warranty or even an extended warranty if they are buying one.
