RE: 140TDI DPF with Adblue

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?

Car has done 2 regens in no more then 600km is this normal also both regens I am aware of have been when car has turned off?

Think I am getting paranoid.

Yes i think so. Had mine for 6 years Wouldnt have a clue when its done a regen and as long as it keeps going correctly I dont really care

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

Just did another top-up of AdBlue as the range was down to 3,500kms and we are heading off on a 5,000km journey to Melbourne next week. Interesting, the price of AdBlue was now 99c/L at BP (at the pump). It has gone up 16c/L in 2mths...

Just always remember to turn the ignition "on" for 30sec prior to "starting" the car after topping up AdBlue (re-sets the info in cluster).

Ah diesels and cities. Not the best of friends. The DPF issue is one of the least understood parts of diesel ownership in my experience and discussions with people. People are attracted to the claimed fuel figures, so buy a diesel. Then they hardly ever do longer trips.
