Hi Philip,

In very simple terms, the jack must be able to take at least half the car's weight. Actually, to be safe, you'd have to say a little more than half, just in case there is any variance between passenger and driver side. Every car has its own weight distribution and centre of gravity, but for the purposes of this, imagine a car with its weight perfectly distributed. Position the jack in the middle of the side of the car and jack it up. When viewed from the front or back, the centre of gravity moves to the side of the car not being jacked up, so as the car goes up, the jack is actually under less strain than when it started.

With all of these things, we would recommend building in a safety factor, of course, and use a fixed stand to hold the car up before you go underneath it.

Hi Afeez,

I’m assuming that’s a 1.6 HDI diesel model? If so you need to watch for excessive black smoke from the exhaust, which could indicate a blown turbo. Check too to see if the diesel particulate filter is working properly — if it’s a low-mileage car (and that is quite low miles) then it may not have been driven regularly enough to keep the filter clean, and they’re expensive to fix and clean. If it has air conditioning then that needs specific servicing so check that has been done and, if you notice that the car pulls to the left at higher speed, then it might need new front tyres. Other than that check that all switches and buttons are working properly, and that the car has a full and complete service history.

Hi Philip,

I spoke to someone from Kia about this, as it's news to me, too, but apparently, since last year, all suppliers of new tyres must charge this per-tyre recycling fee. That applies to the car dealers as much as it does the tyre depots. This fee is collected by the dealers, sent to the distributors and then paid to Repak. There's zero profit in it and no choice in the matter.

Hi Allan,

Orthopaedic seat covers can help, right enough, but it can be a bit of a process of trial and error, and I’d say the best bet in that instance is to get some advice from your doctor, or your back specialist if you have one. As for cars with the best ride quality, the Yaris is pretty good in that respect (although the heavier hybrid version is perhaps less good), but the best bet is, whatever car you’re going to buy, make sure you go for the smallest possible wheel option, with the largest possible tyre sidewall profile. It’s the secret to a comfy ride.

Hi Anne Marie,

Stop-start systems on cars will stop working for a variety of reasons, some of them outside your control, but if you think your SEAT still has a problem after looking through this list of possibilities, best bet is to get the car along to your nearest SEAT dealer to check it out:

- Ambient temperature too cold
- Ambient temperature too hot (unlikely in Ireland!)
- Battery in poor condition
- Driver's seat belt usually must be on
- Driver's door and bonnet usually must be closed
- Engine temperature is too low
- Climate control settings may force the engine to stay on

Hope that's of some help. This question by an Audi owner has proven very popular and is mostly applicable to your car too.

Hi Sean,

I agree to a certain extent with this, but not completely. Rear-wheel-drive cars with their engines up front (as with your Mercedes) really struggle with traction in icy conditions, but front-wheel-drive cars are no better when it comes to braking and turning in the same conditions so if such a law was to be brought it, it really should apply to all cars, as winter tyres provide much more grip whether you're accelerating, braking or turning.

However, despite the crazy week we've had here in Ireland with snow and ice, long term weather stats clearly show that we don't get enough cold weather in most parts of Ireland (i.e. the temperature below seven degrees C) to warrant forcing everyone to change to winter tyres. Above seven degrees C, winter tyres are not as good as all-weather/summer tyres and they wear much quicker.

The Irish motorist already feels hard done by in terms of taxation and running costs so I don't think any government would bring this in here, but to be honest, I don't think they should, either. It really should be up to the individual. And that's coming from someone that has expereinced how brilliant winter tyres can be. Other opinions area available...

Hi Jane,

I would say that if you're driving as you describe then sDrive is fine, as not only is it entirely capable it's also much better from a point of view of running costs. For normal on-road driving it's perfectly good enough, and if you're worried about winter conditions then consider fitting some winter or all-season tyres.

Hi Paul,

If the car has a full service history and is in good condition, then in general we’d say there’s nothing much to worry about. At 125,000km it’s well within the lifetime of all its major components, and if the history is solid then so should be the car. Just make sure that it has had a timing belt replacement, or at least an inspection of the timing belt.

Hi Cyril,

The A4’s a nice car, very comfortable and refined, but it’s not as roomy as the Passat. Don’t go for the 120hp, as it’s just underpowered. As for reliability and problems, it’s a solid car, but you need to keep an eye on the diesel particulate filter (DPF), water leaks from the air conditioning unit, glove box lids that don’t fit properly and worn seatbelt sockets. Check for signs of uneven tyre wear, and noisy suspension is probably the anti-roll bar drop links. No other major problems to report.

Hi William,

There doesn't seem to be a history of consistent problems with the F10 5 Series rear suspension. The only recurrent problems that we have noted are leaking damper issues. A broken spring can just be 'one of those things' and given the state of many Irish roads, perhaps it's not too much of a surprise.
