Hi Peter,

Diesel cars are now outselling petrol cars by 3 to 1 and of the petrol models that are selling, they are mainly small runabouts. The fact is that the majority of people are being drawn to the lowest possible road tax and in some cases, oddly, this means that they are actually spending more on the car then they really should have. There seems little sense to spend €2,000 - €3,000 more on a diesel car if you are saving €50 a year in road tax and your mileage is low, but that is the way it seems to be happening right now.

The problem with this is that buyers are missing out on on some really good petrol cars. Fiat and Volkswagen in particular have some smart new petrol engines. Take for example the Jetta, which you  mentioned: the new one is out now, but in the older model there was a 105hp 1.2-litre TSI petrol engine and most people baulked at this because they thought it would be too weedy for the car. The same is true of the 1.4-litre TSI, while both are more than capable of adequate performance. 

In terms of fuel economy, sure enough the diesel will usually trump the petrol, but this will only really start to make monetary sense when you do a lot of mileage. It you intend on high mileage, then you are probably better off sticking with the diesel car - Volkswagens are generally quite good at mega mileage, as are Skodas.

We've been getting quite a few queries about DPFs (diesel particulate filters) here in CompleteCar.ie but Mazda appears to be the only brand showing up faults. The Passat though has not been without its troubles and, to be honest, I am not sure if I would be buying a used one with a lot of kilometres on the clock if big mileage is likely.

You mentioned the Jetta, well this one we found would be a top buy. It has just 14,000 miles on the clock, the right 2.0-litre diesel engine and is within your budget. This would be a good buy.

Hi Philip

We spoke to Toyota Ireland and they had this to say about your issue. "There's very little info to go on but the clue seems to be in the fuel used. It could possibly be a knock sensor reacting to octane rating or fuel quality causing the light to come on."

It might be an idea to stick to the best fuel possible and check with your local Toyota service agent. Come back to us if you need more help.

Hi Gerry,

As the Peugeot 508 is brand new there is no way to gauge how reliable it will be. Its predecessor, the 407 saloon, suffered from relatively minor niggles all its life, but first impressions suggest the 508 is of higher quality. The Passat CC, though sold in smaller numbers than the four-door saloon version, has an exemplary reliability record.

In terms of fuel economy and emissions, the 2.0-litre HDi versions of the Peugeot 508 saloon with a manual gearbox emit 125g/km (Band B) and use 4.8 litres/100km (58.9mpg) on the combined cycle. The 1.6-litre HDi models are more efficient, though slower obviously.

In comparison, the VW Passat CC 2.0 TDI (with a manual gearbox again) uses 4.7 litres/100km (60.1mpg) and emits the same 125g/km, so there's virtually nothing to choose between them.

Hope that helps.

Hi Ciaran,

Thank you for your query. The Kia pro_cee'd is a good car, but thankfully the only thing negative about it is the silly name. We really rate the car and it would make a great second-hand buy. It has been a while since we drove a pro_cee'd so we called Kia Ireland to get a reminder on the engines. We were told that very few 1.4-litre petrol models were sold in 2008 and practically none in 2009 after the road tax laws based on emissions were introduced.

The first thing to note then is that the petrol models are scarce, but quite a bit cheaper than the diesels. A petrol model will cost you €9,945 while a diesel from the same year could cost you €12,950 - more than €2,000 more. You certainly won't save €2,000 in fuel and road tax in a hurry, so it depends on how long you intend to keep your car. If you change your car quite often and residual values are a concern then you probably need to get the diesel, but if you will be keeping the car for a long time then you should get the petrol, especially given the relatively low mileage that you do.

In terms of what to look out for, there is nothing. There have been no recalls that we know of and the car has few real faults apart from the fact that visbility isn't great out of the small rear window, but then you can expect that with any coupé-like hatchback.

Anyway, I hope this helps and doesn't actually make it more confusing! If there is anything else don't hesitate to come back to us.

Hi Ally,

That really isn't an easy choice, but what we would say from the start is that you have chosen well. These are three fantastic cars and to be honest, any of them will tick the most basic of boxes for you in that they will be reliable, will be comfortable and look good and offer decent value for money. Mazda offer by far the best value when it comes to the scrappage scheme, so if you are watching your budget then this might be the way to go. You can check out the full details of the Mazda3 scrappage offers here. But the most you will pay is €19,495 for a fully specced Mazda3 under scrappage and that is superb value. 

Mazda3

Ford Focus (left) & Volkswagen Golf (right)

The two cars you see above are the new Ford Focus (left) and the Volkswagen Golf (right) and choosing between these two would be a bit like asking a parent to choose one of their kids. They both have their individual traits and as such it is hard to pick between them. The new Focus is very good, but I have the hatchback this week and had the saloon last week and actually preferred the saloon. The hatchback has poor visibility out the rear and you do have to pay a lot to get some of the fancy extras that are advertised. Having said that, you will get things like alloy wheels and air conditioning in the models you have chosen. The Golf is superb. We are running a long-term Volkswagen Golf Bluemotion and the fuel economy is great. I prefer the seating position in the Golf. I find that I can get more comfortable in the Golf and the fuel economy is outstanding. It isn't as exciting as the Ford inside, but you know that it will hold its value really well.

Really Ally, all of these cars will suit your needs perfectly. If I was tight on bugdet I would probably buy the Mazda3. If you are very concerned about residual value you have to buy the Golf, while the Focus is the newest car and probably feels the most upmarket.

My favourite of these would be the Golf, but whichever one you pick you will have done well. Again I would say that you need to move pretty fast, because if you want a specific new car it can take a few weeks and there aren't many weeks left in the scrappage scheme.

Hi Linda,

It certainly does sound like an injector issue - assuming the coil and plugs are fine. We'd suggest that the injectors are tested before hastily replacing them. Any decent garage will do that for you - it doesn't have to be a main dealer. From the information you've given us about the car, we don't believe you can re-program the injectors. It may be possible to refurbish them, but in most cases it's probably better just to replace it.

If that's what is needed, the cost of the part itself is well over €100, but no garage should charge you more than an hour of labour for replacing it, as it's a relatively easy job.

Hope that helps and you get sorted.

Hi Paul,

Firstly Renault tell us that "All aftersales operations must be performed under very clean conditions and that work should ony be carried out by quailified person/s."
 
The Fuel filter is located behind the wheel arch liner on the driver's side.
 
1/To gain access, remove the driver's front wheel.
 
2/remove the wheel arch liner.
 
Depending on the vehicle,
 
DRAIN THE WATER IN THE FUEL FILTER - Drain the water in the fuel filter periodically

1/For filters without a water presence sensor: open the drain plug, let the water flow out, close the plug.

2/ For filters with a water presence sensor: disconnect the water presence sensor offset connector, unclip the water presense sensor connector, loosen the water presence sensor by one turn, let the water flow out,tighten the water presence sensor.

I hope this helps. If in doubt, seek the help of a trained service technician.

Hi Declan,

The Passat is a lot of car for a 1.6-litre engine to pull along, so depending on how and where you are driving it then your fuel economy might not be super. Is the car brand new? In the running-in phase economy can be a bit down on post run-in performance but perhaps have a look at your driving style and eliminate that as a possible problem first.

It is possible on the Passat to look at the instantaneous consumption so keep an eye on that and make a note of it and the average values. 

I've been through enough fuel economy challenges at this stage to know that it can be often down to our own driving (and I include myself) in this. Nobody really needs to 'drive' a tonne-and-a-half car down a hill and being a little more delicate with your right foot can make a massive difference (110- vs. 130km/h on a motorway for example). 

Aside from all that, keep a note of the car's performance over 2-3 days then make a conscious effort to change your driving for the next few and if there is no massive difference then perhaps see about getting the car checked over. 

Come back to us with actual figures, mileage of the car and how it is used and we'll try to give you more assistance.

Hi John,

It was developed in-house by the Hyundai-Kia Group for fitment in a wide range of future vehicles. It is a six-speed unit. The driver can choose from two operating modes - fully automatic or ‘Sport’.  For city driving, fully automatic mode is ideal, while ‘Sport’ mode allows for clutch-less manual gear changes for greater driver involvement - either using the centre console selector lever or the new steering wheel-mounted ‘paddles’ (standard on all automatic models). 

The paddles  enable the driver to change gear without taking his/her hands off the steering wheel.  Pulling the right-hand paddle towards the driver changes ‘up’, while pulling the left-hand paddle changes ‘down’.

Although the six-speed transmission is a regular ‘torque converter’ automatic, it incorporates a unique ‘flat’ torque converter, with three planetary gear sets and four pinion differentials - ensuring, according to Hyundai, ultra-fast, smooth and precise gearshifts throughout the engine speed range - and it weighs just 78kg - 20 kg more than the manual gearbox.

Its layout makes this transmission the most compact six-speed unit currently available anywhere in the world according to Hyundai.  It is 54 mm shorter and weighs 12kg less than a regular five-speed unit and boosts fuel economy by up to 12 per cent.  Like the i40’s six-speed manual, the automatic is a ‘filled for life’ maintenance-free unit. 

Automatic transmission-equipped i40s will feature cruise control and Hyundai’s ‘Active Eco System‘ economy indicator to assist with fuel-efficient driving.

Hope that's enough information?

Hi Caroline,

Paddy here. Given your budget, I would say that you need something that is going to be easy to live with, cheap to run and reliable. 

The Suzuki Swift is a really easy car to own. It is reliable, spacious, cheap to run (tax, fuel, insurance) and good value too. This one I have picked out because it has really low miles (10,000km) and is about half way up your budget: Suzuki Swift

Another decent buy would be a Ford Focus 1.4 - which is a really good larger family hatchback with a big boot. This one we found has just 34,000km on the clock, comes from a good dealership and the price is good: Ford Focus

At the upper end of your budget would be a Volkswagen Golf. They are really good investments because they hold their value well. This one again has really low mileage: Volkswagen Golf

I hope some of these are of interest. I think the Swift would be a super choice for you guys though. 

Come back to us if you need more advice though.
