    I was talking to the mechanic who does my roadworthies yesterday and he told me many of the new diesels with DPF are having the same problem.
    He said that Mazda 3 diesels particularly make lots of oil and have an "X" above the full mark that should not be exceeded. LOL
    As an aside he is somewhat of a Subaru expert and told me that the new Subaru engines with timing chains are using prodigious amounts of oil so much so that 2 customers had run out before the next service was due and been given new engines by Subaru, and the new engines were using heaps of oil.

    My 2007 Pathfinder 2.5 diesel with DPF was doing the same thing, oil level just kept going up. I was happy to change it for a non-DPF D4!

    Interior parcel tray inop

    Hello,
    Wondering if anyone else has had an issue with the boot tray/seat folding down? Can hear motor working but no movement.

    Has been a couple of failures on the UK D5 site of the folding tray / seat assembly.

    so looks like it’s not a isolated incident.

    *DPF (or DPD) technology is not something new, its just been poorly implemented in the light vehicle industry to quickly meet high emission standards.
    *DEF (diesel exhaust fluid) .... or adblue technology is the next step after DPF (see above) technology and vehicles dont use both.
    *One big thing an engine needs to overcome to meet better emissions is internal friction (of the engine parts). To reduce internal friction manufacturers do two main things. Use a thinner oil and increase the clearances of internal parts. The down side of this is a greater consumption of oil and the likely hood of greater fuel bypass leading to oil dilution.
    *Oil dilution from fuel bypass and oil consumption has always been part of a internal combustion engine.
    *Typically older designs of engines are suffering more of the oil consumption and oil dilution issue.
    *The two obvious ones that come to mind are the V8 diesel as used in the Land Cruisers and the V6 diesel as used in the Discovery (5). Both are realistically (due to modern emission standards) past their design life.

    15,000 kms & my 3.0 tdv6 has just come up with the Oil Service message for the second time in it's life.
    The oil was changed & a software patch loaded last time.
    It has also just reached 2,400km to the AdBlue being empty for the second time.

    As you can see from the low AdBlue usage - I don't do short trips & do a lot of 80 km/h+ driving.

    It's going to be interesting ...

    Mine has been in twice for an additional oil change, at 3 months (4,500km) and 6 months (10,000km). The first oil change was a week before the N222 campaign came out, this was applied earlier this month with the second oil change under warranty.

    I've done about 1,500km since the service and the service indicator has gone down by a similar amount. There's hope, it looks like the early service warning is fixed. As for the additional oil changes, people that had had their oil tested report a lot of wear metals the first time, settling down after subsequent oil changes. So I think it's actually good for the car to have its oil changed early.

    If it cannot even make 10,000 km between FREE changes - then that is a major issue & nuisance, let alone the potential longevity issues to the engines.

    I'm pretty certain that the exhaust system of the D5 uses a DPF as well as a SCR, the latter using adBlue/DEF. I'll see if I can dig out a diagram from the workshop manual.
