A friend of mine has just bought the car stated in the title from a small trader. It's only done 51k in 6 years and is in apparently good condition although the outer edges of both front tyres were worn more than normal.

I know nothing about Mazdas or diesels for that matter, but I did swot up yesterday and read that they had DPF issues. I mentioned this to him before we went to view the car; in other words, you may have a large bill if a diesel engine lunches itself.

He bought the car this morning. Is there anything I can tell him to tweak/fix/get checked to avoid anybpotential issues? This really is for a friend, not me. He hasn't got a huge disposable income so I want to help him avoid garage bills as much as possible.

Thanks in advance.

Leading question, but what is his driving profile like?

Is he, regular long trip with high speed sections.

Short trips, town driving mostly.

The first is ideal for a DPF equipped diesel allowing opportunity to regen (i.e. burn the soot out of it).

The second will clog it up and kill it.

A Mazda dealer could force a regen or he takes it for a 100 mile cruise at 70 for similar effect. (doing a long trip regularly would allow a short trip cummute pattern in between)

30 mile commute 5 days a week on A roads, so 50-60mph at best. He said he does about 250 miles a week all in. Maybe once a month there may be a long motorway journey (100 miles plus).

I did mention clearing out the DPF with a good run. It's a chain rather then belt unit isn't it?

It's like a catalytic converter, on the exhaust system near the engine.

I think he'd be fine with that sort of driving. He'll probably never even know it's there. I had a diesel for about 3 years and the DPF just quietly got on with it. I was doing short motorway journeys twice a day though (about 22 miles), so that was likely enough for it to regen as it went.

If it ever wants to do a regen and the roads aren't conducive to it, there'll be a notification light on the dash and it'll increase the revs automatically if the engine is idling. You're not supposed to interrupt it once it starts I was told. I never saw it get that far though.

I used to do about 400 miles a week in my 2009 Mazda 6 diesel and only had one problem in all that time which was a leaking injector which caused a blockage and oil starvation. Fortunately I stopped as soon as the oil warning light came on and so didn't cause any further damage.
I've recently changed it as I'm now only doing about 80 miles a week and have gone back to petrol.
