Hi Jim,

Sorry for the delay in getting back to you, but I was checking this out and there certainly seems to be something of a difficulty with the diesel particulate filter in the Mazda6 although in general Mazda cars are really very good. There is ancedotal evidence of problems with the DPF and we have had questions on the site from owners relating to this, who were seeking to remove it altogether. With any used car it is pretty impossible to predict if the issue will occur so perhaps it might be worth considering another model, which is a shame, because the Mazda6 is a really good car otherwise.

Here is some more info, from a Mazda6 forum.

Hello Ailis,

Well for a start you have forgotten about the new Mazda5, which could be right up your street and it comes in €2,000 less than the Ford C-Max . It is a really impressive car and has a 1.6-litre diesel engine, which is frugal and puts it into Motor Tax Band B. It isn't quite as engaging as the C-Max to drive but it is well equipped and feels like a very high quality product. Here it is:

€24,995 will get you the entry-point into the Mazda5 and we think it is a really good car and would seem to suit your needs. 

While it doesn't have sliding doors, you simply must try the Peugeot 5008 because it is so good. Click on the link to read our full review. That would make a great buy.

With regards to the Ford Grand C-Max you need €26,995 to get into the 1.6-litre Activ model. 

Out of all of these, Ailis, I think you should really consider the Mazda5.

Hope that helps!

Hi Ed,

We contacted Mazda on your behalf and they advised us that you should contact a Mazda dealer to have this looked at. It might be something simple, but it really needs to be diagnosed in person rather then through a description.

Sorry to not be of more help this time.

Hi Ronan,

We asked Ciaran Lowe, a former service manager for Nissan Ireland, to answer this one. He told us. "I can understand your reasoning for removing the Diesel Particulate Filter (DPF) because of the excessive cost of replacement. However, the DPF on diesel vehicles plays an important roll in reducing vehicle emissions. In fact these filters can reduce diesel soot emissions by up to 80 percent, so by removing the DPF it is interfering with the emissions on your vehicle. By re-mapping the ECU it is only tricking the engine management  system to see emissions within spec regarding the DPF system. However even with the ECM re-mapped the vehicle will still fail any future emissions tests. The fact your light is on indicates the system has identified out of range emissions."

I'm afraid the best solution all-round is to seek a used DPF filter.

We've talked to a few people in the industry and short of messing with the actual lights in the dashboard there is no way around this. We can't recommend this route, but it could be done by any auto electrician.

Hiya Alan,

In a word, no we wouldn't recommend a used one. While the RX-8 is a great car and was super when it came out new, it has been a total disaster in terms of reliability. It drinks oil and fuel and there is a list of problems with it. There is a fair amount of evidence that the engines on these cars aren't lasting much more than 80,000- to 100,000 kilometres and there have been problems with starting the engines too. 

We would love to recommend the RX-8 as a second-hand buy but there is a strong chance you would be heart broken and given the fact that you have had grief before then I reckon you don't want that to happen again.

Hi Sean,

It really depends on your budget and how many seats you need, but you can't go too far wrong with something like a Ford C-Max, Mazda5 or Peugeot 5008. These are probably the best around at the moment. If you need more room, then a Ford S-Max or Galaxy is your best bet. But come back to us if you need a more detailed response and can give us an idea of your budget. 

I hope this helps.

Hi Mairead,

I guess it depends on how bad your Ibiza is. You will generally get a better deal as a cash buyer, but it will also probably cost you money to get rid of your Ibiza if you bring it to a scrap yard. Sadly you don't qualify for scrappage. but there are lots of good offers around, especially from the likes of Renault, who will give you a great scrappage price on a car eight years old or over. You could have any Renault Mégane within your budget. We recently drove the GT Line version of the Mégane and it looks great with tons of equipment including a built in TomTom navigation system. 

The Mazda3 diesel is €19,995 and you get air conditioning, Bluetooth, cruise control and alloy wheels as standard and it is a cracker of a car. I think given your budget that this would be an excellent choice. It has low emissions too, so annual road tax is just €104. 

Feel free to come back to us if any of these suggestions don't work.

Hi Hany,

I guess this depends on you budget really and whether you can get the full scrappage allowance from Renault on your Fluence. If your car is ten years or older then obviously this car becomes very cheap and therefore very appealing.

If you are asking which is the best car of the two then I would say that the Mazda3 is a better car. It feels a little better built, has a better diesel engine and will almost certainly be worth more in three or four years time. 

However at the moment, the Fluence is so much cheaper that it really is hard to ignore it, so all things being equal, at the moment the Fluence is probably a better buy. I hope this helps!

Hi Tim,

I am presuming this is 56,000km and that the car is in good condition. You are likely to get offered around €16,000 - €17,000 for this car as a trade-in. But you might get a little more depending on what you are trading in against.

You can buy an example with about half as many miles as yours for about €19,000 as you see here. Generally the dealer will offer a little less because they have to service and prep the car before they sell it. 

Keep our estimate in mind as somewhere to start really. And also, don't to get fixated on what is being offered for your car, but rather the cost to change. And remember to shop around! 

I hope this helps,

Hi Mick,

If you talk to the trade at the moment, they will say that there is something of a shortage of good used cars around. Generally as people buy in the early parts of the year then you will get a lot of second-hand cars floating around so there is a case for waiting. On the other hand, your 2006 Vectra is regarded as another year older. If you can get the right deal why not do it now? 

The only thing to worry about is a shortage of diesel Mazda6 models from that year. You didn't specify if you wanted petrol or diesel, but there are twice as many petrol examples available. Having said that, I really like this diesel model here, but it is a little on the pricey side. You would pay significantly less for a petrol model with lower mileage, such as this one. 

What I would say is that you will get more attention in the dealerships now, or at least you should do. It can be frustrating going into the dealers in January when they are busy, so bear that in mind.
