Hence there is no chance that us guys in Europe will be able to match the economy figures you Aussies can achieve. However, the difference is not quite enough to cause me to want to emigrate.
This is much worse than the 2011 i30 I have... In my case, the regeneration is fixed to 700 km (435 miles) and it does 1-2 regenerations per tank.How much does the MPG change in your case, Alan? My trip computer usually goes from 5 l/100 km (47 MPG) to 7 l/100 km (31 MPG), which results in ~2% increase in total economy figures (0,1 l/100km). It is not much but is definitely a joy-breaker This equates to 25 kilometers less per tank...
Thank god we do not have those DPFs here in Australia.
There's a pressure sensor before and after the DPF. They compare readings in pressure and are used to define when to regenerate. I don't think it's fixed intervals. As your car is still very new, there's probably not very much soot in the DPF and thus there will be longer between the regenerations in the start.
I faced the dealer with the data I recorded and they did not have any good explanation.I can export the log of regenerations for the whole 61k kilometers, but on general it appears that the interval is fixed to ~700 km (the log is here: http://www.poraba.com/usage_other_view.php?type=25888&carid=11497)

I would be interested to get the same info off my car - if only I knew how.

However, it would not be hard to read the exhaust gas temperature and wait for the temperature to raise above 600 °C. I had a plan to do something like that but had not had time yet.
Why did I do this? I hear you ask. The answer is because the manual says that if the engine warning light comes on to indicate a forced regen is required - run the car at 2000 rpm for about 20 minutes. So I thought that if I kept the revs above 2000 rpm the soot would not build up in the DPF so quickly and the regen. intevals would be much longer.

it so happens for the past month or two I have been keeping the engine revs at 2000 or above on the cruise. The display tells me to change up from 4th to 5th and 5th to 6th at about 1750 rpm - but this drops the engine revs to less than 1500 rpm after you change gear. I have therefore delayed changing up so that the engine is doing around 2000 rpm in the next gear.Why did I do this? I hear you ask.

After reading about the DPF regen I'm glad I've a petrol.Although I had a diesel previously it didn't regen.
