    2004 V70R high miler resto - advice welcome!

    This isn't my first Volvo, but it's the first one that needs major work done.
    I bought this high mileage example last week with the idea of refresh it, keep it and use it. It's done 383.000km (roughly 230.000mi) and has been maintained in the same Volvo service until 350.000km. I'm the third owner and bought it from a Volvo enthusiast who also owned a 240turbo, V70r, etc... These are the photos that were sent to me before going to see the car:

    On the phone seller told me 4x4 isn't working and it isn't the haldex (angle gear it is), airbag and engine check lights had been on for a couple of years, 4c isn't working because of new regular front shocks and it's recently developed a major oil leak through the crankshaft seal, timing side (pcv??).

    Next steps are fixing the oil leak and angle gear and perform a stage 0, buy 4 Monroes and paint it. I'm also thinking of buying a second hand engine just in case, what do you think? I'm open to suggestions and advice!

    With that many miles on it I'd be looking at rebuilding the engine, at that mileage it's going to have a fair bit of crud in the engine (especially if you're looking for the power). Strip it down and replace all the seals and a cylinder head refurbishment.

    If the engine is out you may as well look at refurbishing the turbo too.

    And a new PCV system to finish it off.

    +1 to the above - get a spare engine &/or a full rebuild. Don't forget to shim the liners.
    It must have had a replacement Turbo by now but even if it has the budget for a new one - as the KKK's can be prone to premature failure. Although some.have been known to last over 160k with no major issues. It a lottery!

    Good luck with the restoration.

    Cheers, Morgan

    Hi there,

    I recently put a deposit down on a higher mileage ‘06 wil 312k miles on the clock so will be keen to see you progress and equally I will be passing on my story. Mine comes with extensive history and has been converted to lpg at 106k. Turbo was replaced at 280k along with charge pipe. I will be picking it up next week and expecting the worst but work for it’ll be a long term rebuild like yours.

    Good luck

    Quick update #1

    Bought a VIDA DICE and searched for problems. Erased the airbag problem (didn't come on again) and ETM (fingers crossed) and some others that seemed related to a faulty battery. Car still feels lazy and seems to accelerate more with partial throttle load than WOT.

    Ended up with this:

    Beam adjustment signal... no idea what that is
    Hydraulic pressure faulty valve... no idea, but I knew AWD isn't working
    Fuel pressure... ordered a new sensor, hoping it isn't the PEM
    Rear heated oxygen... ordered a new one
    Shock absorbers... ignore, it's on T5 fronts

    quick update #2

    Bought a chinese compression tester... dunno if calibrated but at least you can compare values between cylinders. Did the test with cold engine; with hot engine values are 1bar higher. I don't know how much I can trust the tester, but cyl2 is 1 bar lower than the others both hot and cold and the others should be between 11-13 bar, amirite?
    Anyway, I think this values put me in rebuild land and I'm not willing to do that anytime soon. So, for the time being I bought a well maintained shimmed engine from Shemtek.

    Photos of the values, cylinder 2 is the last one:

    thanks for the info on DEM0007, definitely worth a try if it's the least expensive part of the AWD system!

    I think it's the PEM, any ideas on how to check it?

    Can you check what duty cycle the fuel pump is running at? Signal too high would be fuel pressure high possibly so there may be something causing that like the ecu compensating for something that has been remedied.

    Maybe worth pulling the battery to reset the ecu adaptions?

    In VIDA, when reading live values, "fuel pressure nominal" is lower than fuel pressure". To me that means ECM isn't requesting higher values. I understand "nominal" is the request value...

    Nominal would mean the lowest acceptable value, but if it's a live value then I'm not sure what Vida means, sorry.

    What is the pump duty cycle at when idling?
