Hi Dody,

It’s a belt and it needs changing every ten years or 200,000km, whichever comes sooner.

Expert answer

Hi Colin,

Well, according to our data the timing belt only needs to be changed at 100,000 miles or 160,000km, or every ten years, so it should be fine for a while.

Hi Irvin,

Well, it kind of depends what you want and what you need. These are two very different cars, so it's a little tricky to compare them directly. The Audi is stylish, comfy, refined and reasonably spacious, and of course comes pre-loaded with buckets of premium appeal. The Fiesta is, by contrast, rather more cheap and cheerful, but it's utterly brilliant to drive and, with that 1.4-litre diesel, should cost little more than buttons to run.

So, as I say, it depends what you need. Want space and premium appeal? Get the Audi. Want cheap running costs and a pin-sharp driving experience? Get the Fiesta.

Let us know which way you go

Hi Shane,

Ok, if you want to trim your tax, then your best hope is to get into a much more compact car. I'd suggest trading down to a five-door hatchback, and seeing as you do such low mileage, I'd suggest going for petrol - you'll find it much less trouble than diesel. 

How about a Skoda Octavia 1.2 TSI petrol turbo? Near to diesel levels of economy but no diesel particulate filter (DPF) to worry about, Band B emissions so you'll pay just €280 to tax it and it's also nice to drive and damn near as spacious as your old Mondeo.

Hi Pat,

You definitely need to change both belts. The recommended change interval is 125,000 miles (just over 200,000 kilometres) or every two years. If yours has never been done then we'd suggest you get it done as soon as possible.

Hi Bernard,

An individual injector is going to cost in and around the €170 mark, depending on where you source it from. After that, it’s down to the garage you bring it to and what kind of labour rates they charge.

Hi John,

Nothing major to worry about although there are a few electrical glitches - the keyless ignition system (if fitted) can give trouble, as can the hands-free locking and unlocking (again, it was an option). There have been isolated reports of the 2.0-litre diesel engine cutting out unexpectedly too. Check the interior trim carefully as well - Mondeos often rack up big mileage and while the mechanical bits are sold, the cabins can suffer from abuse - look for collapsing seats or disintegrating trim.

Hi Dan,

Of all the ones you've mentioned there, I'd actually have a long, hard look at the Volkswagen Jetta. True, it's not the most exciting car of all, but with the 1.6 TDI diesel engine coupled to the DSG automatic gearbox, you should be able to squeeze terrific fuel economy out of it: 55mpg should be easily do-able, perhaps even the sunny side of 60mpg. It's sweeter to drive than you'd think too, really comfy and built like a tank.

What do you think?

Hi Patricia,

Both 1.8- and 2.2-litre TDCi engines in the S-Max have timing belts. The change interval is 200,000 kilometres or every two years.

Expert answer

Hi Louise,

That car has a timing belt, which should be replaced every 125,000 miles (or 200,000 kilometres). We'd recommend changing it sooner than that, however, say every 100,000 miles, so it would be a good idea to have it changed on your car sooner rather than later.

Hope that helps
