Hi Joan,

The N47 engine, BMW’s mainstay 2.0-litre turbodiesel, did indeed give terrible trouble early in its life, mostly with the timing chain that was supposedly maintenance-free, but turned out to be nothing of the sort. Now, theoretically, the issue has been long since dealt with (any N47 from 2007 onwards should, emphasis on the should, not suffer from this issue), but it’s wise to be at least a little cautious. I’d recommend buying from a main BMW dealer, as the car will then come with the full two-year warranty, which will cover any potential issues. Make sure you keep it serviced with a main BMW dealer in future too, as if there are any problems, you will have some chance of getting them to stand over the engine.

Hi Emma,

I think a hybrid could well suit you, and with your M50-heavy driving (especially in stop-start traffic) it could prove ideal. The IS 300h is indeed a lovely car — beautifully built and good to drive, but you might find that the cabin and boot are on the small side for your family needs. It could be worth looking at the larger GS 300h (same engine, similar real-world economy) or maybe the NX 300h crossover. If you fancy something a bit cheaper, the Prius is always a good choice, as is Kia’s really rather good Niro hybrid.

Hi Samie,

It depends which engine exactly you have in your Fiesta and when it was manufactured. For both the 1.4-litre and 1.6-litre TDCi engines, there was a changeover in schedule that occurred for cars made later in 2010. Before that, the timing belts in the diesel engines were scheduled to be changed every 200,000 kilometres or every 10 years, but after that, for a brief period of manufacture, it changed to 140,000km (still 10 years) and later again back up to 180,000 kilometres.

We always encourage readers to err on the side of caution with timing belts, so would advise you to consider the 140,000km interval as applicable to your car.

Hi Barry,

The problem with electric cars is that, generally, they’re not rated for towing (I think that the new Nissan Leaf is one of the first with a towing rating), so you’re probably going to have to switch back to petrol or diesel for this one. Probably your best bet is to go for something very conventional, such as VW Golf or Ford Focus, and maybe go for the estate version of one of those to give yourself a little extra versatility. A Toyota Auris Hybird would also work well, and would at least keep you going on half-electric power. Plenty of them around in your price range.

Hi Roddy,

Well, it sounds definitely as if petrol is the way to go, and as you’ve mentioned the Ateca, that’s a good one to look at. It’s cheaper, by a little, than most of the competition, has an excellent 1.0-litre 115hp turbo petrol engine (don’t be put off by the small engine — it copes just fine) and isn’t ‘smaller’ at all — it’s the same size as the VW Tiguan, thanks to using the same chassis. The same goes for Skoda’s Karoq. A Peugeot 3008 with the 1.2 PureTech petrol engine would also be a good choice, but the Sportage isn't currently offered as a decent small petrol version, so we’d give that a swerve. The Nissan Qashqai comes with a good 1.2 turbo petrol, but doesn’t feel as good to drive in that form as the diesel. The Opel Mokka X is just too old a design and feels well out of date, but actually if you can cope with the smaller size, the Suzuki Vitara’s a good shout — good to drive, good looking and hugely reliable.

Hi Jan,

The 1.6-litre diesel Mazda3 of that age has a timing belt. It must be changed every 240,000 kilometres or every 10 years, whichever comes first.

The 2.0-litre diesel engine also has a timing belt, which must be changed every 120,000 kilometres regardless of time.

Those intervals are the same for all markets and conditions.

Hi Vis,

There’s plenty of choice at that price level for a 2008-onward diesel, but the mileage you’ll get will vary hugely according to how you drive. For instance, you could get a 1.6 HDi diesel Citroen C5 saloon within your budget, and that’s capable of doing 60mpg or better, but again that comes down to how you actually drive it. In terms of reliability, you’ll never beat a Japanese brand for that, so go for a Honda Civic 2.2 CDTi, a Mazda3 1.6 D, or a Toyota Auris or Corolla 1.4 D-4D.

Hi Seamus,

The same size, yes, but they are very different engines. Actually, both engines also have the same 130hp power output, but without question the Peugeot engine feels livelier to drive than the Renault one. Why? We can’t say, but the effect is definitely there. Economy should be fine though — especially seeing as most of your mileage is around town, you should get a pretty easy 40mpg on average. It’s definitely the best engine option for you. At 7,000km a year you’d be wasting your money buying a diesel.

Expert answer

Hi Chris,

If it has the 1.3-litre CDTi diesel engine, then it has a timing chain.

The 1.7-litre CDTi diesel engine has a timing belt that must be changed at least every 10 years or 100,000 kilometres, whichever comes first. 

If it's the older 1.7-litre 'DI' or 'DTI' diesels, that's 150,000km or 10 years.

Hi Eamon,

Lovely car, the CX-7. Never got the love it deserved. Assuming that it’s the 2.2 diesel model you’re looking at, it should work out at around €3,000 in VRT to bring one in, but that will depend hugely on condition and spec.
