Hi Kevin,

The mk1 Ford Focus was offered with two different diesel engines over its lifespan: the direct injection TDDi and common rail TDCi. Both systems use glow plugs with reports suggesting that the more modern common-rail unit has marginally more issues particulairly relating to cold starts. 

We hope this answers your question. If you require any further information feel free to let us know.

Hi Sean,

Nice choice of cars to be thinking about. Before we look at the stats of the cars, the driving experience in the 3 Series vs. the Audi A4 is quite different - and will be the deciding point for many, so please do try to get a test drive in examples of both. That's the case whether you go for the older 3 Series Coupé or the newer saloon.

Personally, I prefer the way a 3 Series of this age drives in comparison to an A4. It's more 'dynamic' and engaging thanks to the rear-wheel drive layout. However, not everyone likes that and I've heard non-enthusiastic drivers call the feeling 'skittish'. There is no doubt that a front-engined, front-wheel drive car like the Audi A4 will find more traction on snow and ice than a rear-wheel drive BMW (assuming neither has winter tyres), but our climate is too mild for that to be a serious car-buying priority.

In terms of running costs, the early versions of the E90 BMW 320d saloon and Audi A4 2.0 TDI 140 are very close and, as you'll be buying a car registered before 2008 with that budget then tax will be the same, as it's based on the engine size. The E46 320Cd coupé is a little heavier on fuel, but not much.

The 320d saloon has the most powerful engine of these three, though there's not much in it really.

Both saloons are generally quite reliable, though we'd recommend getting full service histories and getting mileage checks with Cartell.ie as each car has its own known issues that crop up from time to time - like turbo issues on the BMW and burning oil in the Audi. The E46 coupé is also reliable, though it's built on older architecture so won't be as modern in general.

One final thing to bear in mind. While the S line Audi specification is highly tempting, it comes with firmer suspension, which may not be to everyone's taste. Test drive it before committing. Likewise an M Sport version of the BMW 320d, though you may not find many of those within budget.

Now, whether you should consider petrol instead of diesel is a whole other story. The decision really should come down to your average mileage. The diesel models will definitely be far more economical on a long run or commute, but not in town. Likewise, you can get lower capacity engines in the petrol cars bringing your annual tax bill down.

If you want to discuss the latter point in more detail come back to us and we'll go through options.

Hope this all helps

Hi Susanne,

We really like the Audi A1. Despite its smaller size it'll feel like a big step up in terms of quality etc. from your 2002 BMW 3 Series. A nearly new model will cost you very little in terms of servicing as well and there's a wide range of efficient petrol and diesel engines. Our favourite is the 1.2 TSI petrol, though if you cover a high average mileage (say greater than 15,000km a year) then it's worth looking for the 1.6 TDI diesel version instead.

If you'd like more detailed assistance to find one that suits your budget feel free to get back in touch.

Hi David,

The short version is, I’m afraid, you’re going to struggle. Small cars such as that don’t generally sell well with diesel engines, as the petrol variants are very economical already, and the diesel versions are much more expensive. We’ve found one on Carzone.ie (a 2005 VW Polo TDI),  but that was literally the only one we could find on sale that fits the bill. You might want to consider upgrading to a larger car — there are lots of diesel Golfs etc around in your price range.

Hi Michael,

We've not heard anything about this one to be honest, but that doesn't mean it's not a problem! Since 2008 the vast majority of the Zafiras sold have been diesel so there are not many petrol versions around now.

Hope that helps

Hi Peter,

It looks like nobody working with CompleteCar has driven this combination. The CVT is only offered with a 1.6-litre petrol engine in Ireland and our experience of any CVT gearbox with any petrol engine is not good. It is smooth, as there are no gear changes as such, but engine revs don't often correspond to forward motion, so it often feels that the engine is revving unnecessarily. CVT works well enough with diesel, but not with petrol engines.

Saying all that, you really should try it for yourself before discounting it completely.

Hope that helps.

Hi Teresa,

We spoke to Volkswagen and I'm afraid there's no permanent way to switch this off that it recommends. You'll just have to do it manually each time you start up if it bothers you.

From our perspective, this feature is becoming more and more common and we think it's a great idea. If all cars on the road used it think how much fuel could be saved in town. Likewise - and in contrast to what you've said - noise pollution would be reduced overall thanks to the lack of engine idling noise at traffic lights.

Don't worry about the starting motor wearing out either, as most cars with stop-start have heavier duty starters, along with systems to monitor their condition and prevent it being over used.

Hi Mel,

As that car was registered pre-2008 its tax is based on engine size. For engines sized between 1,901 and 2,000cc the price is currently €660 per year. That change in January of this year following the Budget.

Hi Lukas,

There are many different models of diesel Opel Astra, even for 2007. There were 1.3-, 1.7- and 1.9-litre CDTi engines that year, plus three-door GTC hatch, five-door hatchback and estate. Not to mention different mileages and trim levels.

The latest selection from Carzone.ie suggest a price variation of between €5,000 and €11,000.

Let us know specifics if you'd like us to help some more.

Hi Mick,

The 1.6-litre TDI engine has 105hp, which doesn't sound like much, but it's the engine's torque that matters more in the real world, and this Passat has 250Nm from just 1,500rpm. It's more than enough for the Passat in most circumstances and as all the performance is low down in the rev range you don't really change down to overtake.

Saying all that, if you plan on towing or you drive with a full car regularly you'll appreciate the extra power of the 2.0 TDI engines, but most people will find the 1.6 perfectly acceptable.

Hope that helps.
