Hi Anna,

There are several versions of that car, and there as a model year change in late 2009 so it depends which it is exactly. Here are a few examples, assuming you're not talking about the estate:

- 1.8 TDCi saloon with 100hp and five-speed manual gearbox: 149g/km CO₂ (Band C): €390

- 1.8 TDCi saloon with 125hp and stop-start (called 'Eco') and five-speed manual gearbox: 139g/km CO₂ (Band B2): €280

- 1.8 TDCi saloon with 125hp and five-speed manual gearbox: 154g/km CO₂ (Band C): €390

If you give us the registration number we can give you the exact price of tax.

Hi Tom,

If the stop-start system is not working ever then it's probably worth a trip to your Audi dealer to have it looked at, but bear in mind that there are plenty of conditions in which it will not operate and it may not be immediately obvious why. Here's Audi's official stance on it:

"The system is automatically activated when the ignition is switched on. If the driver doesn't want to use it, it can simply be switched off at the touch of a button.

"This is how it works: brake the car down to a standstill, shift into neutral and release the clutch. The system now switches off the engine and signals this via an indicator lamp. Depress the clutch before continuing the journey - the engine now starts automatically and the indicator lamp goes out again.

The start-stop function only works when...

• the driver's door and the bonnet are closed
• the driver is wearing a seat belt
• the vehicle has been driven at faster than 4km/h before stopping
• the vehicle is not pulling a trailer

In some cases the engine will not be switched off, for instance when...

• the engine temperature is still too low
• the difference between the interior temperature and the temperature selected via the air conditioning system is still too great
• the outside temperature is very high or very low
• the windscreen is being de-iced
• the optional parking aid or the optional park assist is activated
• the battery charge is too low
• the steering wheel is at a sharp angle or is being turned
• reverse gear is engaged
• the road is steep

The engine is started automatically by the system when...

• the vehicle rolls forward
• the windscreen is being de-iced
• there is a large difference between the interior temperature and the temperature selected via the air conditioning system
• the brake pedal has been depressed several times in succession
• the battery charge is too low

Hi Mary,

First off, no you're not crazy. The Clubman is a terrific little car and I actually own one myself. It's more practical than you might think and much more distinctive and different than the standard MINI Hatch. Secondly, on the alloys - blistering could mean that the paint finish is peeling off or that the metal underneath is starting to corrode. It may be that you could simply sand down the bubbles and have the wheels resprayed, or you may need to budget for some replacement wheels.

The only major mechanical issue is a recurrent gearbox problem that can lead to failure and replacement. As long as it shifts gear cleanly, you should be OK. Don't worry if the shift feels heavy, as they are supposed to feel like that. 

Other problems are persistent interior rattles, issues with the stop-start system and a windscreen that seems to be peculiarly prone to cracks and chips. No issues with the timing belt as long as the service history is up to date.

Hi Peter,

You're really comparing two quite different cars here. The Auris is a larger car than the Jazz, which is really more of a rival to the Ford Fiesta. Which means that the Auris is going to be more comfy and refined over a long distance, but if you're sticking mostly around town, go for the Jazz. There are no reports of the Auris' stop-start system causing any issues, but the Auris has been generating reports of problems with squeaky front brakes, slipping handbrakes and noisy gearboxes.

The Jazz, by contrast has generated no repeating fault reports and Hondas are usually incredibly reliable. Yes, parts can be a bit pricey for them (the Toyota would be cheaper to service and repair), but so few things go wrong that you probably won't need to spend much. Go for the Jazz so - it's sweeter to drive, has a cleverer interior and will probably prove more reliable.

Hope that helps

Hi Dawn,

Nissan quoted a combined consumption value of 5.4 litres/100km (52.3mpg) and we'd expect most drivers to get in excess of 40mpg (7.1 litres/100km) so long as all journeys aren't in stop-start traffic.

Hope that helps

Hi John,

Yes, but with one small caveat. The Prius has always been one of Toyota's best, and indeed best-built cars. It's essentially a flagship model, particularly for Toyota's eco-friendly ambitions. There have been a few recalls (for malfunctioning brake lights, airbags, steering and brake issues, as well as the infamous sticky-throttle-pedal one), but generally Prius are solidly reliable and there have thus far been no reports of fading or failing battery performance. We've heard one or two reports of rust breaking out, but they're probably most likely down to unattended panel damage exposing bare metal.

The caveat? It depends how and where you drive as to whether or not it's worth buying a Prius. Yes, you'll get cheap road tax, but to get even vaguely close to Toyota's quoted 65mpg fuel economy figures, you're going to have to drive with the reticence of a trappist monk. Get anywhere in the neighbourhood of enthusiastic driving and you're going to see the fuel economy plummet, ditto for undertaking any long motorway journeys. But, if you spend most of your time in town, where the Prius' electric motor and stop-start systems can best bring their armament to bear, then the economy should pick up, and you'll have one of the most comfortable, reliable and relaxing cars in which to hustle your way through city traffic.

Hi Ollie,

Generally speaking, you should be OK, as that 30-min run each day should be enough to keep a DPF hot enough to clean it out, but that’s if and only if that 30 mins is all run at high-ish speeds, say above 80km/h most of the time and in a lower gear. If you’re spending a lot of time in stop-start traffic, I think a petrol option might still be the better one. Mazda’s 2.0-litre petrol engine can be a bit thirsty, but the 1.4 TSI option in the Passat and A4 is a very frugal engine, and still has peppy performance.

Hi there,

It depends on your driving style, and on where you do most of your driving. If you’re in town all the time, and stuck in stop-start traffic, then it could be worth tracking down a Toyota Prius or a Honda Insight hybrid, bot of which should sip fuel in such circumstances. If you’re up on main roads and motorways all day long, then diesel is still a good idea. A VW Golf 1.6 TDI BlueMotion would be a solid bet for maximum economy then, although if you fancy something a little more stylish, a MINI Cooper D (with the 1.6 diesel engine) will crack 60mpg on a long run.

Hi Daniel,

You've not told us which of the Insignia diesels you're looking at, and whether you're buying new or used, but in general Opel's diesel options in the Insignia are a little on the loud side. However, they all give good performance and economy, and the latest come with stop-start.

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.
