Hi John,

If you're buying an Irish car then you'll be very limited in terms of choice. The vast majority of 2010 Ford Focus on the roads in Ireland are powered by the 1.6-litre TDCi diesel engine, in either 90- or 110hp states of tune). It's not a bad engine with a great performance-to-economy ratio and low road tax. Be aware though, like many engines of this type, it's only really suited to average annual mileage of 20,000km and above - or the majority of its time on a fast-flowing road/motorway. The reason is that its diesel particulate filter (DPF) can clog up and it can be expensive to remedy. There are other components in the engine itself that also gum up if the car is used predominantly for low-speed driving.

Other engines in the 2010 Focus are the 1.8 TDCi diesel and, for low-mileage drivers, the 1.4- and 1.6-litre petrol units. All of these are much rarer. The 1.8 isn't quite as susceptible as the 1.6 diesel to issues, but it's less economical. If you're sure that diesel suits your needs then seek out a 1.6.

Hope that helps

Hi Louise,

You don't necessarily need a 4x4 for that - a mid size estate car would do the job just as well. So, have a look at the following and see what you'd like: Mazda6 2.2d, Ford Mondeo 2.0 TDCi, Skoda Superb 2.0 TDI.

Or, if you really have to have a 4x4, check out the Hyundai Santa Fe, Audi Q5 or Nissan X-Trail.

Hi Stephen,

If it won't turn over at all it sounds like the battery is flat (it takes a lot more charge to turn the engine than to light up the dashboard) or the starting motor has stopped working. As you mentioned slow degradation I'd suspect the battery, and perhaps the alternator isn't working to full efficiency. Best bet is to get a good mechanic or auto electrician to sort it out.

Hi Matt,

We asked Ford for an official adjudication on this, and here is the response:

"Each vehicle/wheel has a specific offset and wheel width regardless of tyre size. The 7.5J x 18 referenced for the Kuga wheel means that that wheel is 7.5 inches in width and the S-MAX referenced is running 7J x 17 meaning the wheels originally fitted were seven inches in width. Therefore, the answer from Ford is no - we would only recommend like for like replacements."

Hi Martina,

That model Ford Focus TDCi has no pump in the tank, so it can't be that. The only thing that we can think is an issue with the fuel filter or its housing, perhaps letting in air. I'm afraid the only thing for it is to bring the car to a good mechanic to assess. Best of luck,

Hi Elizabeth,

Ok, there's a simple answer and a not-so-simple answer. The simple answer is that the Fiesta is more economical. Going by the official figures, you'll get 78mpg on the combined cycle from the Fiesta (and that's for a model without the stop-start system fitted) and 57mpg from the Audi (that's the 125hp engine with a manual gearbox and 16-inch wheels).

Now, the not-so-simple bit. It depends on how and where you drive. If you drive mostly short journeys and mostly in town, then the diesel is not going to give its best, and that 78mpg figure is pure fiction anyway. I'd say in daily driving you'll probably get closer to 55mpg. The Audi, if driven with a bit of care and attention, should easily get 40mpg, even around town. So there's a gap, but it's not so big as you'd think.

The reverse is true if you're doing lots of long journeys at a steady motorway cruise. The Fiesta would come into its own and you''d probably squeeze 60mpg, maybe 65mpg from it. The Audi probably wouldn't get much above 45mpg, maybe a bit less, doing such journeys.

Hi Kevin,

Official guidelines are 125,000 miles (201,000km) or every 10 years. We'd recommend being more cautious than that.

Hi Craig,

Best to get it along to a mechanic pronto, though before you do, check the oil level and top it up if it's low before you drive anywhere. It's likely there's an oil leak within the engine bay, though it could well be leaking oil into the cylinders too if there are larger issues so best to have it checked by a professional.

Hi David,

I'd say you've already picked out the ideal car - that Octavia 1.2 TSI is magic. Plenty of oomph, very economical and should have enough grunt to haul that trailer. One thing though - at 500kg, that trailer is getting on for the maximum braked towing weight of 610kg, so if it's an unbraked one it might be worth trading it for a braked version, just to keep some margin for safety.
