Hi Gavin,

I'm afraid the registration you gave us came back as a Hyundai on Cartell.ie, so we assume there's a typo there. However, looking at the 2008 Focus:

1.4/1.6 petrol: timing belt

1.6/2.0 TDCi diesel: timing belt, with small timing chain at back of engine joining the camshafts

1.8 TDCi diesel: timing belt, with separate belt or chain for high-pressure pump drive

1.8/2.0 petrol: timing chain

Hopefully that covers your car, but come back to us if not, with more details.

Hi Tomas,

Well, the NOx tax isn’s about the size of the engine, it’s about the NOx emissions, which are not specifically related to the size. It could be worth getting on to the Japanese Ministry of Land, Infrastructure, Transport and Tourism, who may be able to provide you with a specific NOx figure for the car you’re talking about, but otherwise, just be thankful it’s not a diesel — those are subject to a maximum €4,850 extra in NOx tax if you can’t provide an accurate figure.

Hi Shaun,

That engine has a timing belt. It should be changed every 210,000km regardless of time.

Hi Wafaa,

Well, obviously vehicle weight will vary according to engine and equipment, but let’s take the best-case scenario in all cases: petrol engine and a manual gearbox (except in the case of the Toyota, which is only available as a hybrid). The officially quoted kerb weights are: Opel Astra 1.2 Turbo - 1,205kg. Renault Megane 1.3 TCe - 1,231kg. Toyota Corolla 1.8 Hybrid CVT - 1,345kg

Hi Mick,

You should be able to get a figure from the Japanese Ministry of Land, Infrastructure, Transport and Tourism. According to Revenue: "If a NOx figure cannot be provided for a vehicle then a flat charge will apply.” For a petrol-engined car that’s a maximum of €600, so it’s not the worst news in the world (a diesel-engined car would be charged as much as €4,850).

Hi John,

There's a lot less going on in the exhaust aftertreatment of a modern petrol engine than the equivalent diesel so I suspect the diesel needs the warm-up more. It may also be due to the extra strain on the starter and battery due to the high compression of the diesel engine. When the oil is cold, the friction may be higher, causing a higher strain again. 

Either way, it's nothing to worry about.

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 Michael,

That engine uses a timing chain.

Hi Mike,

Unfortunately, Revenue and the VRT process are inexplicably cruel in this regard. You have to pay the money before you appeal, but the good news is that more than 50 per cent of appeals are successful. It would be helpful to find some expert in Japanese vehicles (and I would suggest tracking down a garage that imports them regularly) to give you their opinion on the value, as Revenue is legendarily awful at coming up with reasonable values for unusual cars.

As for the NOx charge, I would ask for a statement in writing from the VRT/NCT office that you brought the car for inspection before January, but were told to come back afterwards. That might (emphasis on the might) get that waived when you make your appeal.

Hi Peter,

Very roughly speaking, its performance is equivalent to an old 1.4 or even 1.6-litre petrol engine with no turbocharger.
