Trouble is Donna you don't have a leg to stand on!
Very much buyer beware!
If of course you were told by the salesman that 'this car is perfect for you, shops and back every day' then you might have a case!
I agree the DPF issues are a fiasco but they have been brought on by the need to achieve lower emissions from all combustion engines. DPF is a way of achieving this with diesel cars.
The Catalytic converter started the whole boat rolling with petrol engines.
The DPF only works when really HOT.
An engine only gets HOT when on a long journey.
A trip to the out of town supermarket isn't going to be long enough, yes your temp gauge is in the middle but the engine hasn't got up to its ideal temperature and that means the exhaust where the DPF is. I'm sure you knew that!
We have another problem that afflicts transverse engine cars, like the Evoque and Discovery Sport.
The position of the DPF is not ideal! Land rover are not the only car company that has issues here, BMW amongst others, all have problems.
Quite simply if you want a diesel engined car, with its main benefit, fuel consumption, then the exhaust gases have to be cleaned.
It may be referred to as EU 6 or whatever but it is a worldwide thing, let's not forget Dieselgate in America! Volkswagen and others doing there level best to cheat the emission laws in the USA!
Europes emissions are slightly more lenient by the way, so let's not have any European prejudice please!
This is a worldwide bid to reduce our ever increasing pollution.
There is a simple rule, buy petrol for short journeys and diesel for long journeys.
If you have deep pockets then go for a Hybrid or even total EV (electric Vehicle). iPace is a brilliant car but a little out of most people's budget!
If you like taking your car to a garage once a week, then a Tesla might fit the bill! It is a bit cheaper, but its reliability record is abysmal!
Is there an answer, well actually yes, Hydrogen!
Methane can be used but as it is only about half the thermal efficiency of Hydrogen is comes in a poor second.
Hydrogen produces water when burnt in air. No NOX, no CO2 it is a win win solution, but it is costly to produce.
The easiest way is to pass loads of electricity through water, that can be done at night by nuclear power stations!
Stuck in a traffic jam on the motorway, get out and have a drink from the exhaust! Pure clean water, a bit warm I grant you but clean!
Best
