RE: 140TDI DPF with Adblue

[Asahi1985]

If your trips are long enough to get oil to operating temperature and keep an eye on idle revs before shutting down (air-con off). If idles at around 1000rpm, likely doing a regen. With fans running after shutdown, can also be just cooling down. Had that happen once in 2 years since buying mine but it was after driving in close to 40 degree heat.

Regen occurance depends also on quality of diesel that you fill up. BP Ultimate is the only one in Oz being close to european standard, followed by Vortex Diesel. Anything else is crap in my view.

There is no need to trash the engine just to blow cobwebs out, 110kph on motorway does the job. Do 30-40kms trip at least here and there, maybe at least once a month. Diesel engines are not really built for suburban driving, they are long-range engines and need regular exercise.

Thanks heaps for the advise I will note everything you just mentioned. Did a few hours today but got a cracked windscreen on my 3 day old car totally gutted.

If it makes you feel any better. I took out a Kangaroo down South @ 4 weeks old.

Also, the premium Diesel in WA (and I'm pretty sure other states) for both Caltex and BP is the same. They come out of the same refinery and have the same additives.

Hi ope126,
Are you sure it is doing a regen?
I find the idle speed is very dependent on the pressure applied to the brake pedal .
Light pressure will result in an idle speed over just over 1000 rpm, but with a bit more pressure the speed drops to around 800 rpm (assuming you have start-stop de-activated)
Only done about 1600km in my car, and have noticed it has performed a regen only twice; it is very obvious as the radiator fans are going full bore.

As per the this post, solution has been found!
It is just the pressure that I apply to the brakes when stationary.
Obviously I need to apply full pressure, not just a light pressure (which I have done with all my cars in my life).

Thanks for the info though!

Only applying light pressure may also partially engage the clutches in a similar fashion to slipping the clutch on a manual. Also creeping in traffic by lightening off on the brake is a no no if you want clutches to last. Stop it, hold it stopped, remove brake foot completely, let it roll.

bonus: you also might save your gearbox a bit of unnecessary wear

Question about DPF: If you are not aware that your car is on a regen until you turn it off and the fans are howling. Are you better to restart and go for a drive or leave it be?

Here is what appears to be some answers from VW tech support around DPF's I have found on a UK site. Maybe this will help, applies to all dpf engines.

DPF Regeneration Information - Must read for all drivers of DPF equipped cars - MkV (Mk5) Golf, Golf Plus & Jetta - uk-mkivs

Took the car to VW today and was advised that the DPF is fine, no build up what so ever. Must have just been me not being firm enough on the brake pedal as described earlier...

Had the AdBlue topped up whilst getting the 12mth / 15,000km service today (only 5,000kms on the ODO).
The AdBlue info has been reset and now displays 10,000kms range.

Here is some info from the Volkswagen UK site; http://www.volkswagen.co.uk/technology/diesel/adblue

Interesting info regarding the AdBlue Capacity; 13 Litres (approximately)

1.89L Top Up Bottle (with Adaptor) VW Part No. G052910A2

I have tried searching but can't find a clear answer...
Can you "top up" the AdBlue at anytime?
Or do you have to do a complete "refill" when the first warning message appears?

Also, has anyone used an AdBlue bowser at a petrol station yet? Are they high flow nozzles or are they suitable for light vehicle applications?

Suitable for light vehicles, flow rate is no difference to a standard fuel pump. Some require a magnetic adapter applied to the end to allow for liquid flow, this is normally with the cashier. You will tell if there is nothing happening at the pump.

Also as a warning do not do a whoops put adblue in fuel tank this is even worse and more expensive that putting petrol in a diesel
at my work (am a heavy truck driver) several drivers have done this and ruined a motor to the tune of 80k! this includes total engine rebuild and compleate replacement of fuel system from tank all the way to injectors its bad ju-ju vry corrosive

Yes.

You can pay a small amount at the dealers service dept, or you can fill at any fuel shop* that sells it. It's cheap stuff - pump price is around a buck a litre. I would buy from the dealer as it comes from sealed containers.

*I don't use the name "service station" anymore - no 'service' at any of them.....they are just fuel retailers these days.
