Owning a Diesel in the city

[Greg Roles]

The only similarity I notice between modern Porsches and my TDI are the number of wheels....

Not entirely correct. I think you will find the Europeans have an "optional extra" of a spare wheel where we seem to get a spare wheel (if you can call a space saver a wheel) free.

The technology initially introduced into Porsches and the like eventually trickles down into VW then Skoda/Seat in progressively more affordable (and sometimes reliable) forms.

With emphasis on the "eventually".
As you said, the trickle down tends to happen from the most expensive marques progressively down to the more affordable (cheaper) ones in the order of cost. My point was that the Skodas received some of the recent diesel technology before the corresponding VW models which goes against this.

Have alook at the light switch on both cars

I thought Porsche utilise a lot of the same internal equipment such as window switches, dual climate control, head unit etc? Or at least they were until the last model revision?

I have been a bit concerned about the DPF regeneration in our 1 year old Golf MkVI 77tdi.
The car does a lot of inner city short trips, which is not the ideal I know. The DPF light has come on a few times through the year, and a good run has cleared it.
However when driving it the other day it was going through a regeneration and I found the motor was a bit "jerky" and was very easy to stall (had to really keep the revs up to it to stop it from stalling) - is this normal? And should I be worried about the DPF light coming on so often?

Of course they use similar or the same basic components across the range where they can that's common sense from a business point of view. Whet we are talking about is technology improvements, things like new suspension designs or the latest advances in engine management or manufacturing processes, new gearbox technology or the fancy electronics things like adaptive cruise control, HUD's, in car Internet connectivity. All of these types of things always start in the premium cars in any range at premium prices then as the manufacturing costs of the technology decrease the items spread down though model ranges to the base type vehicles or vehicle ranges.

The forced regen cycle will reduce the drivability of the car as it injects extra fuel during the exhaust phase so that it can end up the the DPF to burn off the soot so all sorts of weird behaviour can result.

I would be a bit worried with any DPF for a mostly city run car.

Wow i used to live at seaview downs , would have taken me to the city 30mins 15 years ago in peak hour , is it really that bad now 1.25 hours .

Yep, every year more and more roadworks.

So more than the number of wheels then!
