That really shouldn't be the case though, should it?

No it shouldn't but unfortunately it seems to be commonplace.

Which adds to the argument for mis-selling...

It's a still a bit of a stretch to claim that the 40% increase in mpg you saw with the diesel is evidence of diesel mpg being worse than petrol cars around town! As above, the number of diesel powered taxis would also suggest otherwise.

To get back on topic, I do wonder how taxis with DPFs fair?

Taxis are almost always on so are up to temperature and running better. It's not the town driving that causes the terrible fuel consumption so much as the short journeys. If you're spending all day driving then diesel is going to be the much better option even if you never get above 25mph.

Of course it's not misselling, you were shown a range that they happened to sell and bought one, your choice.
Now if most drivers answered honestly how they really use their cars (instead of totting up reasons to buy the car they liked the image/age/price of) most would be on the bus or on a moped.
Most cars usually have all the bells and whistles to cater for a family of five (or more) while the poor thing normally whizzes about with just the driver in the cabin.

When I bought my car from Arnold Clark, they made a point of telling me and re-telling me about the DPF and even made me sign a declaration to say they had advised me of the impact of doing small journeys. I drive on the motorway 20 miles to work and 20 miles back each day - so a diesel is fine for me.

Not at all, caveat emptor applies. Do your research, go in armed with the information you need. There is no excuse at all in this day and age, especially with the wealth of information available on the internet.

if you tap on a full tin and it sounds like a full tin, tap on an empty tin and it sounds like an empty tin

same applies to a DPF tap it and it sounds empty, the change to the MOT has been brought in to stop people gutting the DPF, so do you really think it will stop at just a visual check to see if the dpf shell is in place ?

It may not stop at that, but we're talking about whats going to happen this month, not what might happen in a years time.

Theres a thread about this on pistonheads - couple of government MOT testers over there - they have been told formally that its just a visual check - the DPF shell must be there.

Thats all they're going to check.

Besides, worst comes to worst in the future, have another one refitted. Not the end of anyones world.

Well if we're going for the doom and gloom, worst case scenario, sure the world might end in the meantime and it wont be a problem.

So, buy second hand! Personally I would never buy brand new unless I was very wealthy, but I might make an exception when I retire and get my lump sum.

I would suggest break-even point is around 25k but that's open for debate.

Depends on the car.

I've a 2012 Golf 1.6 TDI and its averaging a brim-to-brim mpg of 65mpg. Best over an entire fill was 69mpg, worst was 61mpg.

Thats over 12,000 miles.

The new TSi engines are getting around 40mpg, and there are that many diesel golfs out there the price difference is minimal therefore the breakeven point will be much lower in my case.

Definitely important to do your own sums though and buy whats best for you, not what the rest of the herd happens to be doing.

Have you never seen them going for a burn-up down Park Lane?

That is mainly to clear out the exhaust in non DPF cabs.

Euro 5 Vito and TX4 have DPF.

All Addison Lee have DPF.

Galaxy system is very reliable. Not really effected by stop start running around.

Did 20k in an AddLee Galaxy around the Olympics.

Dpf light not on once.

But Ford do use data from the AddLee fleet with vehicle development.

Older dpfs can get a new lease of life when cleaned by companies like Ceramex or DpfGenie.

Ash forms when soot is burnt off during regen and that clogs the filter over time.

This needs to be burnt off at temps higher than usual regen and for longer.

Buses and LGV dpfs have been cleaned this way for years.

The build up of ash is why dpfs need to regen at shorter and shorter intervals as they get older.

As soon as i have the money is shall get the Jag done.

In the meantime JLM dpf cleaner added to the tank seems to mean i only have to take the car for a run every 900 miles rather than 300.

Mine was much better before a failed sensor meant a forced regen at dealer.

I think the sensor and forced regen resulted in excess ash reducing capacity before it is full of soot
