I have to question whether a modern Euro-V spec diesel is really the right choice for someone whose main use of the car is 5-10 minute journeys to work?
Not sure if the NCT inspects the DPF closely, in the same way as the UK MOT is meant to (and is starting to be enforced), but I would suggest that if it's possible, you'd be well advised to remove/core the DPF and have the EGR blanked off too.
... and you wouldn't be the first person to question it either. I thought long & hard about it myself.
Here in Ireland, our govt all but wiped out the market for petrol cars. In 2008, they introduced a CO2 based motor tax system that favours low emission cars. Overnight, people switched from buying mainly petrol to mainly diesel cars. E.g. the annual
motor tax for a 2.2JTS is 950 / £750 (manual) or 1200 / £880 (selespeed). As a result, hardly any were sold here when new - and that impacts the used market too. There are very few decent petrol ti 159s available here.
This is why I eventually settled on the 1.9JTDm ti saloon. It never missed a beat in the two years I owned it, so I had no reason to suspect the 2.0 ti sportwagon would be any different. I'd have loved a TBi ti sportwagon , but even in the UK, they are few & far between. When they do come up, they sell very quickly. As a result, somebody like me trying to buy from Ireland is at a disadvantage because a UK based buyer will be able to move quickly to buy it. Also, TBi's are still quite expensive (stg £11 - 14k). When I add in the 3-4k Irish import tax on top of the £stg price, I'd be looking at 20k landed cost for a 5-6 year old Alfa. That's crazy money.
So, while the 2.0JTDm isn't ideal for my mileage, it's a compromise I have to make if I want a decent spec ti at a reasonable price.
I'll see how I get on with the NCT & then look at DPF removal / blanking
