All of the manufacturers must be doing something similar to VW.....Im not surprised renault is..
I have a question though... To help reduce emissions on startup a lot of diesel engines have additional heater units fueled by diesel.... Do the
combustion gasses from these heaters play a part in the overall readings?

Good question! I happen to know that our 2001 Y plate Alhambra had a diesel powered heater to help warm the interior of the vehicle before the engine
warmed up. In our case it was disconnected as it didn't work, but having looked at it to see if I could fix it I can advise it had it's
own exhaust pipe so I'm guessing the emissions were not part of the engine test results.
I believe my 57 plate Passat also has a diesel powered heater unit - given VW (and it will be others) record here I'd hazard a guess that
emissions were directed elsewhere for any test.

Agreed, they will all have been doing it otherwise VW would have been caught sooner!
VAG by all accounts have a lead on TDI type engines so they were likely to get hit hard by it, but they will all have been up to no good.

One other thing to add on my part here...
I've driven TDIs for many years and whilst they're not the last word in refinement or power delivery for daily drives they're hard
to beat. Reliable, pokey, light on fuel when driven right and generally I like them.
My favourite it has to be said was a Seat Leon TDI PD150bhp - fast car, good to drive and peaked at close to 70mpg on a drive from Stockport to
Winchester (slipstreaming an HGV). Other than that a pair 138bhp Passat estates have also been more than adequate if not fast transport - huge boot
space too!
SWMBO now has a Touran (Golf based I believe) which seems very good too. Only a 1.9TDI 105bhp, but moves well and swallows a large load too.

I would also add that I had a Volvo V50 1.6 diesel for a while. Shamefully bad car (sad as I still think it's a great looking car from the
outside), but it did perform well economy wise.
One nice trick was changing the Volvo lettering on the boot to read ovloV, which raised a few smiles in the rear view mirror.
Volvo (probably hampered by Ford) chose to make a little storage tray, but located it behind the dashboard fascia panel. Shame as the dash looked OK,
just hampered by a daft storage tray.

A petrol car of similar size will return similar MPG in similar circumstances.
It is in stop start traffic diesel pays off because diesel aren't throttled allowing much better volumetric efficiency. A idling diesel engine
burns very little fuel compared to a petrol engine.
Because of the higher carbon content DERV is about 20 percent more dense than petrol hence some of the savings of running a diesel are due to
measuring fuel consumption in units of volume / distance not mass /distance.
It would do the environment much benefit to adjust the tax regime to reflect the higher carbon content and swing the balance back in favour of petrol
enginesfor cars.

It strikes me that petrol has fallen out of vogue and diesel has been on catch up technology wise - IIRC it's not that long since people got
excited about common rail injection on diesel engines when petrol has been done that way for a long time. Personally I like a diesel engine and the
rattle noise is largely under control now.
