Hi Martin,

Yup, the problem is that 2008 was the switchover year to CO₂-based taxation, and the old Toyota petrol engines were pretty high up the charts in that respect. Actually, are you sure it’s 1.4? Because we only have data for a Corolla Verso with a 1.6-litre engine from that year. That engine had emissions of 177g/km, which would account for the high motor tax cost, but in theory a vehicle bought in 2008 should be eligible to revert to the old engine capacity system, which would bring down the cost a little. It’s certainly worth raising the issue with your local motor tax office to see what’s possible.

Hi Rebecca,

You've not given us the year or engine size, so here's a summary:

Kuga gen 1 (2008-2013): both engines (2.0 TDCi diesel and 2.5-litre petrol) use timing belts that must be changed every 200,000km or 10 years, whichever comes first.

Kuga gen 2 (2013-2020): the 1.5 and 1.6 EcoBoost petrol engines and the 2.0 TDCi diesel engine have timing belts that must be changed every 200,000km or 10 years, whichever comes first. The 2.0-litre EcoBoost petrol engine uses a timing chain. 

Unusually, the schedule for the 1.5 TDCi diesel engine's timing belt replacement depends on the model year. Up to 2018 it's the same as the others above, but after 2018, the interval is reduced to 180,000km.

Hi Joseph,

I'm afraid that's impossible to say as no two engines will be the same. It will depend on a lot of factors, including the design and construction of the engine in the first place, how well looked after the engine was throughout its life in terms of maintenance and how hard it was used.

Hi Francis,

It’s actually pretty brilliant — that 1.6 iDTEC engine is one of the best diesels we’ve ever sat behind. It’s smooth, has plenty of performance and is very economical. Plus, Honda engines were never implicated in any diesel emissions cheating, so your conscience can remain untroubled. The rest of the car is rather lovely too. Honda’s quality is a given and that generation of Civic is both massively roomy and massively versatile with those clever flip-up ‘Magic’ rear seats. It’s also good to drive — not as agile as a Ford Focus, but solid and planted, with nice steering feel and good comfort levels, too. The only demerits are a bit too much road noise and a slightly messy dashboard layout.

Hi Mark,

The government knows the emissions of each vehicle simply because each vehicle is put through a series of official laboratory tests as part of the process of homologation — the legal process whereby a car is pronounced as passed for sale to the public - and that data is made available by the car manufacturers. As for which is cheaper to tax, it’s down to the CO₂ emissions and we’d have to know which make and models you’re looking at before we could give you a precise answer, but in most cases, for a given car, the diesel would have lower CO₂ emissions and hence motor tax.

Hi Gino,

That Ford 1.6 TDCi diesel engine is one of the most common engines around, as it has also been used by Mazda, Volvo, Peugeot, Citroen and MINI. It has one major vulnerable spot and that is that sooty, gummy deposits can build up in areas that are supposed to be kept cool and lubricated by oil. If the deposits build up enough, they can block the oil passage and cause component failure — most commonly of the turbocharger. The best way to prevent that happening is with regular servicing (at least once a year depending on mileage) and making sure that you always use a high-quality grade of synthetic oil for the engine.

The 1.6 petrol engine, the 100hp version, is a much simpler unit and it’s pretty reliable, mostly because it’s a much older design. It won’t be as economical nor as punchy in its performance as the diesel, but if it’s reliability you’re looking for, it might be the better option.

Hi Kevin,

It would have been useful to have more details about the car, such as age and engine, as it varies considerably. I'll deal with the 2013 on model, which is still in production.

All 1.2-litre petrol engines:
 - up to Sep 2014, 180,000km/10 years
- Oct 2014 to Apr 2017, 175,000km/10 years
- from then on, 100,000km/6 years first, then every 200,000km/12 years

1.5-litre BlueHDi diesel: every 180,000km or 10 years

All 1.6-litre diesel engines: 175,000km or 10 years

All 1.6-litre THP petrol engines: timing chain

1.6-litre VTi petrol engine: 150,000km or 10 years

All 2.0-litre diesel engines: every 180,000km or 10 years

Hi Donal,

Well, fuel consumption depends very much on your own driving style and where (and to an extent when) you do most of your driving. That said, in general, we wouldn’t expect that 1.0 TSI engine to be much thirstier overall than the 1.6 diesel. In our tests, both engines are in and around as economical as each other and you should expect to get around 50mpg from either with a light foot. The diesel may be a little better than the petrol option at a sustained high-speed cruise. However, with such low annual mileage, we suspect that the petrol engine will cost less to maintain in the long run. It's probably the best option for you.

Hi Nigel,

We know of an issue with the clutch assembly that causes what sounds like engine noise in the naturally aspirated 1.0-litre Polo engine. In the 1.0 TSI models, apparently a fault with the engine control unit (ECU) can cause whining from the engine as well. Neither of those sound like the problem you have, though.

Hi Tony,

The second-generation Octavia launched in 2004, which means you're most likely looking at two completely different generations of the model. There will be some small number of parts potentially shared across both, but not a lot at all, especially as the engines are also different.
