Mazda 6 Diesel Problems

If you’re happy with the Mazda 6 wagon – and it sounds like you are - then there’s a good case for sticking with the Mazda brand. And if that’s the case, the next thing to consider is which model and body style. Given your requirement for a car that is easier to get in and out of, I reckon a mid-sized SUV might make the most sense since it’s footprint will be similar to the Mazda 6 you have now, but it sits you higher and more upright. On that basis, the Mazda CX-5 seems the natural choice.

If you go for the petrol-engined Touring model, you’ll get all-wheel-drive for extra grip and safety as well as keyless entry and start where you can open the vehicle and start the engine without even taking the key from your pocket. Very convenient. If you can afford a little more, the GT model gets you the powered front seats you need and these even have a memory function that will automatically adjust them to either your or your husband’s preferred settings as a one-button job. Again, very convenient. The GT model also get a powered tailgate which was also on your must-have list. About the only thing missing is the full-sized spare wheel, and all Mazda CX-5s use a space-saver spare. But be honest, are you going to change a flat tyre yourself, or call roadside assistance? And when was the last time you experienced a flat tyre anyway?

It is rated to tow 750 kg if the trailer doesn’t have any brakes, or 1600 kg if it does have brakes. The Passat diesel will also tow 750 kg with an unbraked trailer, but 1500 kg when the trailer has brakes. There are no major concerns with either of them.

We understand Mazda released a revised engine oil dipstick with a higher full mark. It also released revised software for the dpf operation that changed the way the self-cleaning function took place. If you haven’t got those updates I would be approaching Mazda to get your car updated.

I couldn't say with any confidence that the problem has been sorted and I would be reluctant to recommend the car to you given that you travel short distances. I have asked Mazda to comment and will get back to you once that response has been received.

There have been reports of problems with the CX-5 and some other Mazda models of fuel contaminating the engine oil through the DPF filter. Mazda claim to have a fix for that problem. I would check with your Mazda dealer so see if your car is one of those affected.

If the engine is damaged as you state the best option is probably to buy a sound used engine from a wrecker. Rebuilding the engine could cost $5000, a good used engine should be bought for less than $2000.
