CEL, rough running, 'reduce speed or shift up.' 125,000 miles V70-XC70 2008


Wife reported that her '08 V70 started running rough, CEL was on and the display read "reduce speed or shift up." It's obvious when idling in park and of course while driving. Searching online I've found several similar reports of misfire, coil, spark plug or injector in a specific cylinder.

None of the scanners I've tried communicate with the car, even a Volvo / Saab specific iCarsoft unit, so off to the local independent shop it went this morning.

The plugs and coils were replaced two years ago so we'll see what they find. Spending too much time under the hood or our cars so this one I farmed out. Once repaired we'll be looking for a replacement.

    Fixed. Dead fuel injector on cylinder 1 and corresponding fouled spark plug.

      Glad you were able to resolve it!

      The Life Partner's 2015 XC60T6 had the same symptoms this morning.
      Pulled plugs, none looked very good (the car burns oil like it's its job), including some missing insulator on #3. But #2 was black and wet.

      I reinstalled the old plugs I had saved and swapped the #1 and #2 coils hoping the problem would migrate with it. Alas it did not.

      Remove all plugs, check compression on #2. Nada. Plenty on #1, nothing in the #2 hole...

    I think that VIDA-DICE is essential from P2 onward with these cars, otherwise your diagnostics are hobbled. I have a Chinese clone DICE unit and there is a WIN 10 compatible repack of the VIDA available now too, so set-up is pretty straightforward. Given that I already had the laptop, this is a very cost-efficient set-up for reading proprietary codes, resetting SRS lights, etc. Around here nobody reads codes for free at parts stores, so my set-up paid for itself after 2 check engine light scans!

      Hi Herb,

      Thanks for the information on this VIDA-Dice mess! I never heard of this stuff but I live in the recent past of Dark Ages! Like behind more than ten years! Something connected to FWDs. (:-)

      The A of the VIDA is for Aftersales.
      SALES? YEAH! Sure, just to read a warning from my car or for it to communicate to my mechanic? $$$ales!

      Dice … Diagnostic Communication Equipment, this must the working half you buy and have in the trunk!
      Is the “I” for interface?
      I don’t see the I used in the nomenclature. Guess it’s a given?

      I googled those abbreviations and got a whole history of changes and a mention of XP and Microsoft Windows versions. All that turned to junk or is now going as defunct as the desktops and towers!
      They have smart phones out doing them now and who knows what’s up with the folding tablets!

      Looks like you have to repair the OBD or the DICE system by updating it first, in order to even use it.
      That explains why he not getting a reading from other black boxes!
      I see references to a 2015A downloading with a whole bunch before that making things difficult.
      In fact, if you rub around on the keyboard enough a “Genie screen” might pop up with even more revisions!
      I also see the scanners come with scammers! Real fun there!

      Was this car made back when Ford “shared” an interest in Volvo?
      Sure smells like it!
      I hear GEELY wants to sell out of their portion of Volvo, as China wants to dominate their countries electric car sales with basic proven power train designs and then export in quantities!
      Things are in a stir everywhere, between the European and China strengths.

      Microsoft made revisions with every version of anything they made and the public helped them, for a polite thank you! Seldom any paycheck!
      Does Volvo even do that for past customers, of their latest cars, that have terrible maintenance cost reviews?
      I bet VIDA-DICE had a lot to do with that, if it’s still being used?

      I see the car has 125,000 miles and have read on here that it appears that the latest cars are toast at 200,000.
      I haven’t heard that about the mid 2000 years!
      Maybe these are the last of Volvos good blood lines!

      Thanks again for the great update!

      Phil

    Hi,

    I’m a 240 man, nothing newer than 1993, but that sounds like a bad rpm signal.

    The ECU computer must think the engine is doing to much RPM and wants a higher gear.

    Trick is, it might be a transmission code just as easily from the transmission?

    Weird is, you are in Park or driving? It doesn’t know park or speed of the car in this case.
    Misinformation is getting to be a buzz word today! (-:)

    The Running Roughly part, leans me to think it’s corrupt signal from the Crank Position sensor, of which, could throw various symptoms into the computer program for it default into something convenient, but like most codes can be generic.
    There must be other more specific codes!

    Bad timing pluses rattles the brains in the “emissions” department that trips Check Engine Light and that message is not saying anything related to mixture problem.
    CEL is primary made for emission purposes but it doesn’t mean it cannot be used for more.
    The message doesn’t address rough running, so it’s like secondary, with engine speed, but the light came on?
    Yep, hopefully more codes are available!

    The next interesting part is you cannot get a reader to work, that is not normal!
    I’m thinking this car was here before with the two year ago ignition components issue!
    The root source points me back to the CPS, since on 240’s, they can be an issue and we just replace them!

    I’ll be watching this space!

    Phil
