Just a quick question on Euro 5 vs. Euro 6. I recently moved back to the country after 12 years and am looking for a cheap to buy (4-5k) and run diesel family workhorse for which I posted a thread a couple of weeks ago. Just looking at what is available locally, I'm pretty set on a 1st gen Insignia or a 2nd gen Peugeot 308 diesel (not a car that was recommended I know) but they look pretty good value and the GT line spec ones look quite nice (hatchback probably a bit better looking but I think that the SW has a longer wheelbase, so more space for rear passengers and the boot is bigger than a 5-Series Touring/A6 Avant supposedly)!

Some of both examples that I have been looking at are Euro 5 and others creep into Euro 6. Euro6 diesel is ULEZ compliant, whereas Euro5 is not? Would Euro 6 all require AdBlue? I don't really travel in ULEZ zones, so Euro 5 probably not too much of an issue but Euro 6 might be worth more in the future? Presumably you can still take a Euro 5 diesel into a ULEZ zone but there's just an extra fee per day over the congestion charge? Does Euro 6 add more complexity, so potentially less reliable though? I've never owned a car that requires AdBlue, so how does that work?

ULEZ zones are only going to become more widespread, plus resale values will be higher on something which is Euro 6, as you are selling to a wider audience.

If you truly live somewhere that isn't going to have ULEZ zones in the next 5 years, then Euro 5 diesels are a bargain - especially if you pick one up from auction in SW England.

However if you are in a location that may have ULEZ in the next 5 years, just get a Euro 6. Running a Euro 5 near a ULEZ is a complete pain in the arse.

Euro 5 diesel has a DPF and will most likely be pre 2015, I know there are some exceptions, but most Euro 6 are post 2015. I live in the ULEZ zone and had to sell my old Euro 4 diesel to buy a Petrol. To be honest I have not regretted it for one second, I only do around 5K miles a year and getting back in a petrol has made me hate how rough diesel engines are.

We had to borrow my parents car a few weeks ago as we needed a bigger car and the whole saga ended up costing me £50 in ULEZ charges alone.

Basically if you live anywhere near a ULEZ zone get a Euro 6.

I would get a Euro 6 diesel. Note that not all Euro 6 diesels have an Adblue tank. My 66 plate BMW 335d doesn't have Adblue.

The question will be can you get a Euro 6 diesel for that money? Also as the Euro numbers go up, so does the complexity of the engine.

Euro 6 gives you one more Euro than Euro 5

Exactly what was being said when I bought my last Euro5 car two years ago. And the one before that, 5 years ago.

15 to 20k miles a year across the UK and Europe since and still never been into any form of ULEZ or emissions zone.

Unless emissions zones are on your doorstep or somewhere you frequent, I wouldn’t worry about resale value. Trying to get euro 6 for 4-5k means you’ll probably be buying at the leggier/more depreciated end of the market anyway.
I’d be more inclined to go for a better condition, late euro 5 car than euro 6.
Have you considered the mk2 facelift Skoda superb?
Solid build quality, capable of starship mileages (taxi drivers seem to love them) and the boot and rear passenger space are both huge.

The Euro 6 version of my car tends to break a lot more than the Euro 5 so that was part of my decision.

Many Euro 5 versions of an engine tend to be nicer to drive than the Euro 6 models.

The VW Group 3.0 TDI is a particular case in point. The Euro 5 version is a great engine. The Euro 6 version has throttle lag that's so bad it ruins the car.

Without even double checking I know you're referring to an X351.

They sound like a PITA in euro 6 guise, there's a guy on the jaguar forum who changes his oil every 3k.

Agreed, I have a E5 Audi A6 Allroad with this engine and it's an utter peach of a thing - 45mpg on a run and plenty of grunt.

Another satisfied owner with an older car. Previously I owned a Volvo with the euro 6 2.0 diesel, gave lots of eml issues. I sold up and got the same model with euro 5 , the 5 cylinder Volvo have used for years. A fantastic engine and will probably outlive me!

Like others have said; if you're not going near the ULEZ zone, then the older the diesel, the better.
