Hi Olive,

It's not easy to assess such issues from afar though it does sound as if the car is going into 'limp home' mode to protect the engine as the engine control unit (ECU) has sensed a problem. With such a new car it's most likely to be a wrong reading from a sensor rather than anything major.

As the car is new, bring it straight back to the dealer and we're sure it'll be sorted quickly.

Let us know how you get on and what the problem was.

Hi Jerry,

It depends. If you roll it up to a Nissan, Peuegot or Opel dealer in the next few weeks, then it could be worth as much as €4,500 off a new car. As a pure scrap value, at a breakers, it depends entirely on the condition of the car and the various parts that can be stripped from it.

Hi Ruairi,

With that kind of mileage you would probably be fractionally better off with a petrol, but the thing is that you're unlikely to find one - petrol sales collapsed in the wake of the 2008 change in the car tax regime, so it's very likely that all you'll find out there are diesels. 

Which is no harm - the 308 was always nicer to drive with the 1.6 diesel than with a petrol (unless you can track down a vanishingly rare 150hp 1.6-litre petrol turbo). You just need to watch for a few key items. Make sure the diesel particulate filter has been kept clean, and make sure you give the car at least one good long drive at motorway speeds every week to keep it that way. Check that the cooling system is working properly and that the (plastic) water pump is in good nick. Check the gearbox too - the five-speed manual can sometimes get jammed in neutral.

Hi Pat,

As luck would have it I have the latest version of the Subaru Forester on test this very week. It's powered by the 148hp 'boxer' diesel engine, which also has 350Nm of torque. Paired with the 'Lineartronic' automatic transmission it's surprisingly responsive. That's a Continuously Variable Transmission (CVT) and it seems to do a great job of keeping the engine at its optimum operating speeds for a variety of situations. We've not fans of these gearboxes when fitted to petrol engines, but they work well allied to diesel and in the Forester it's a good match.

Officially this Forester 2.0D XC Lineartronic does 0-100km/h in 9.6 seconds, but even at motorway speeds it has plenty of go and it happily cruises above 120km/h.

In terms of comfort, the Forester scores well too. The suspension is quite soft and absorbent so bumps are dispatched with ease and it's relatively quiet on the motorway. The upright seating position is comfortable too.

Shame you don't need the back seats, as they're massively spacious.

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.

Expert answer

Hi David,

I would reckon you'd be better off going for the 1.3-litre Opel. If it's pre-08 it'll have cheaper road tax and given your age I would think keeping the engine capacity down as far as possible would be good from an insurance point of view.

Hi John,

To be honest - no. The current Micra is a long way from Nissan's best effort so I think the €4k trade in bonus could be put to much better use elsewhere. Perhaps consider trading up to a Pulsar? Or better yet, wait a year. Nissan has an all-new Micra coming out next year and judging from the Sway concept car it showed last week at the Geneva Motor Show, it could well be a cracker.

Hi Aisling,

Yes they can, but they may not be the most cost-effective. If you're worrying about the diesel particulate filter in the exhaust getting clogged with soot and causing an expensive failure (and that can happen) then don't worry - a quick spin up and back the nearest motorway in a low-ish gear will heat the system up enough to let it burn off the soot and all will be well. Do it once a week for 30 minutes or so and you'll be fine.

The other issue is simple one of cost though. You will spend more money to buy a diesel car than you will a petrol and when you're only doing low mileage it's hard to generate the savings from fuel burn to make up the extra you've spent up front. That's why petrol makes so much sense for lower mileage drivers.

The thing is that the Qashqai can be had with a petrol engine, but it suffers much harsher depreciation when you buy it - so you're in a bit of a catch 22. Petrol is better for your driving profile, but worse for retaining value in this particular model. You may need to expand your search out to some other cars to make your sums add up.

Hi Ed,

OK, we've been on to Renault about this and they say that the charge for Glacier White on the website was an error and has since been corrected, so you shouldn't be charged for it. If an extra charge does show up on the bill, give your dealer hell as it shouldn't be there. If he/she doesn't give you any joy, get on to Renault's head office about it.

Hi Justin,

We checked with the experts at Michelin for this one. According to them, tyres don't really have a use-by date as such, but neither should you just be blasé about them because their overall mileage is low. Tyres can be damaged or worn by a number of factors, not just how many miles you've done. After five years, Michelin suggests you should have your tyres thoroughly inspected once a year, and after ten years replace them no matter what the condition or depth of tread.
