Hi Brendan,

It's a tough situation for you. We hope you have family and friends to keep in touch with and make sure all your needs are met.

Don't worry about your car. If it's not doing any mileage, then there's no worry about the DPF (diesel particulate filter) or other major diesel components clogging up from low-mileage, low-temperature use. Even if you want to start up your car every few days and let it run for 15- to 20 minutes to keep the battery charged up, that won't have a major effect, not so long as, when we are free to drive where we want again, you take it for a good long run at some decent motorway speeds.

Other than that, keep an eye on the tyre pressures and fluid levels, watching out for leaks under the car. Also, don't park under a tree if you can help it, as it could lead to paint corrosion.

Hi John,

There's a lot less going on in the exhaust aftertreatment of a modern petrol engine than the equivalent diesel so I suspect the diesel needs the warm-up more. It may also be due to the extra strain on the starter and battery due to the high compression of the diesel engine. When the oil is cold, the friction may be higher, causing a higher strain again. 

Either way, it's nothing to worry about.

Hi Sue,

Sounds to us that the battery could be in poor condition. Lots of cars develop issues with their stop-start systems. We get so many questions about it that we wrote a feature about it all - Why won't my car's stop-start system work?

Expert answer

Hi Dave,

I'm surprised to hear that from a new truck where the battery will be in good condition, but stop-start systems regularly don't work as people expect. The system measures loads of variables before deciding whether the engine will be stopped, including the temperature of the engine and even the outside temperature. If it's cold weather, it may not work at all. If you're using items that are a big electrical drain, it may not operate.

Hi Philip,

Well, Tesla already sells a Model S long range that will go for a claimed 610km...

Hi Iobhán,

If you’ve bought a new electric car, talk to the dealer from whom you bought it. All of the major electric car brands have their own charging recommendations and can usually offer you a supply and fitting service. If it’s a second hand one, talk to the guys at ESB e-cars as a first port of call — lots of knowledgable people there and they’re very helpful. As a rule of thumb you’ll need to be able to run a charger with a power output of at least 7.4kW or you’ll not be able to fully charge the car overnight, especially if it’s one of the new big-battery models.

Hi Sandra,

It shouldn't cause any damage, but it could indicate a weakness in your battery or electrical system, so it's best to have it looked at when you can.

Hi Tahir,

The first thing we'd check is the condition of the battery. It sounds like the system is turning off the engine as normal, but then sensing that it needs to go back on right away. That's unusual, to be honest, as most systems just won't turn the engine off if an issue is detected. I'd advise you bring the car to a good mechanic or auto-electrician to have it looked over.

Our feature, Why won't my car's stop-start system work?, is worth a read as well.

Hi Anne,

Is that a 100km round trip every day? Or 100km each way? Either way, you could potentially get away with a fully-electric car, assuming that you can charge at home and charge again at work. Either way, though, you’ll have to spend big and go for one of the latest electric cars with a  50kWh or 62kWh  battery, such as the Hyundai Kona Electric or the new Renault Zoe. What could well be an easier (and much cheaper) option would be to go for a hybrid. There’s only one hybrid-engined car in the Polo-size class at the moment, and that’s the Toyota Yaris. The current version is pretty good, but there is an  all-new one coming next year, so you might be best off waiting for that to appear. By then, the new Honda Jazz, also a hybrid, should be available. Or, you could keep it a lot simpler and go for a new Polo with the excellent 1.0-litre turbo petrol engine. It'll be tough to beat your diesel Polo for outright economy, though.

Hi Sharon,

OK, let’s deal with these questions one-by-one. There are a number of apps available that can give you the locations, availability and in-or-out-of-service condition of charging points. The ESB provides that through its e-Cars app, and there’s a very good independent one called Zapp Map, which also covers the whole of the UK if you’re planning any longer journeys.

All current electric cars (pretty much all brands will have at least one on sale by the end of next year, but for the moment the big players are Audi, BMW, Hyundai, Jaguar, Kia, Mercedes, Nissan, Renault, Tesla and Volkswagen) can be charged at home overnight on cheap rate electricity. The crucial question there is not the car, but your electricity provider and the tariff plan that you’re on.

Finally, battery capacity has been hugely improved in the past few years and, although that does come with a cost penalty, the average useable range of an electric car has gone up dramatically. Generally speaking you should expect to get at least 250-300km from most mainstream models now, with as much as 450km available from some of the more expensive cars.
