The fact that all these features have gone AWOL all at once suggests the display unit itself might be the problem. That, or perhaps a fuse that controls the circuit the display draws its power from. If it was one function on its own, then you’d suspect a sensor for that system might be the problem, but when they all disappear at once, the digital readout unit would be the place to start checking.

However, don’t forget that your car has a five-year factory warranty, and this is most definitely a problem that – on the surface – appears as though it would be covered by the Mitsubishi warranty. Even if you bought the vehicle second-hand, provided the car has been serviced correctly, the warranty should still apply regardless of how many times the car changes hands.

You could try for a computer reset by disconnecting the battery overnight, but make this Mitsubishi’s problem, not yours.

These two vehicles share a lot of traits both in terms of their engineering and their target market. Both are aimed at the high-end of the mid-sized off-road station-wagon market and both do a pretty good job of offering lots of off-road ability along with the sort of luxury and convenience that many families want. In the case of design and engineering they are both based on utilities (the Mitsubishi Triton and Toyota HiLux respectively) and share the drivelines and front structure with those utes. To make them work as passenger rather than load-carrying vehicles, both the Pajero Sport and Fortuner do away with the utilities’ leaf-sprung rear axle and replace it a coil-sprung unit for greatly enhanced comfort.

Both vehicles have had their niggling reliability problems, mainly to do with DPF and some EGR problems, but overall, they’re both now old enough for the majority of the bugs to have been ironed out. Perhaps the biggest packaging difference is that the Pajero Sport is a good deal narrower across the cabin than the Toyota, and that matters for families with bigger kids. Both vehicles were facelifted late last year with new tech and mechanical and performance improvements. Both also have seven seats as standard.

The Mitsubishi is about $4000 cheaper based on RRP than the Toyota, but the final price can vary from dealer to dealer and what state you live in. The best advice is to try each one on for size and maybe even throw in contenders like the Ford Everest as a direct comparison.

This is a really common concern, Raj, especially among people like you who are considering their first diesel-powered vehicle. Modern diesels are very efficient and powerful (compared with old-school diesel engines) but those benefits come with some compromises including higher maintenance costs and potential glitches such as the DPF problems you’ve noted.

DPF problems are usually the result of the filter becoming clogged with the soot from the diesel’s exhaust. There’s not much you can do about a diesel engine producing soot (apart from making sure it’s tuned properly to minimise the soot) so the filter is designed to regenerate when it starts to get full. That process requires heat and that’s where the problems start. A vehicle that is only driven around the suburbs often won’t create enough heat in the exhaust system to allow this regeneration to take place. At that point, the filter becomes clogged and requires either manually cleaning or, in some cases, replacing. Neither is a cheap process.

So, what you need to do is to take the vehicle for a drive at highway speeds to allow things to get hot enough for DPF regeneration to take place. This drive needs to be at least about 20 minutes and it needs to happen at least once a month. So the answer to your question is not really how many kilometres you need to drive, but what sort of kilometres. Even if your four-times-a-week trip to work is, indeed, 50km, if it’s all done in stop-start, low-speed traffic, then it won’t be enough.

The bottom line is that a turbo-diesel isn’t really the right vehicle for a lot of urban-based people. The catch there, is that a lot of vehicles that were once available with a choice of petrol or diesel power are now diesel-only propositions. That includes the Pajero Sport, of course.
