faulty v70 engine control module

    I have a 2000 v70 with 60k miles with faulty engine control module.
    The problems began when we noticed the interior fans on the car
    running full tilt when we returned to it on a hot day. Then the cruise
    control function became intermittent,and then we got the sysyem
    message "system service required". The dealer plugged it in to his
    computer and informed me that it was reporting an internal moule
    fault, but that he had reset it and thought we should see how it goes
    as a new module is about £1000.
    The cruise has continued to be intermittent but at cruising speeds of
    about 60-70 mph the car is quite juddery and last week we got a new
    message " performance reduced" with the engine feeling quite sick and
    sluggish. I've got it booked in with the dealer and feel I know what
    he is going to say.
    Does anyone else have experience of this? I know the car is warranted
    for three years but surely you could reasonably expect an electronic
    device without any moving parts to last more than four years? I guess
    the point I'm trying to make is about quality, after all this car cost
    in excess of £30k new and is useless without a new module, I'm looking
    for strong arguments or evidence that I can put to the dealer in order
    to force Volvo to accept some level of responsibility. Surely Volvo
    would not suggest that four years is good enouh for this quality of
    car and if so, if I keep the car for another 60k miles can I expect to
    have to buy another module?
    Any comments(good or bad), suggestions or strategies that have worked
    in forcing a major car companies hand will be gratefully accepted and
    carefully considered.
    Thanks in advance

    A friend recently had the ECU on his 4 year old BMW give trouble, and
    the replacement was quoted at about £1500. After much searching he
    found one in a scrap yard for £100.

    Might be worth you ringing around.

    This isnt really viable- with the current CanBus Volvo's the ECU's are
    specific to each car- once they have been programmed they wont work with

    I would be back at my dealer, or another one for that matter speaking with
    the manager in no uncertain terms that you expect at least 50% goodwill
    payment, preferably free replacement by Volvo on a part which is designed to
    last the life of the car !!!

  5. Get an opinion from another dealer.

    The interior fan comes on for 5 minutes at full tilt after the car has
    been off for 30 minutes if the A/C has been used to dry the evaporator
    and help stop that "A/C smell."

    Your other problems sound to me like the dreaded and common Electronic
    Throttle Module failure, not anything to do with the Engine Control

  8. 1) That does not sound like the main ECU, perhaps the cruise control?
    Perhaps this site might help, perhaps not, you can e-mail for an opinion:

    2) In the bad old litigious USA Volvo gives this level of protection:
    The Volvo New Car Warranty provides comprehensive coverage for four years
    or 50,000 miles, whichever occurs first. Additional warranties cover
    corrosion, seat belts, the supplemental restraint system, emission systems,
    genuine Volvo replacement parts and genuine Volvo accessories. Please
    refer to the warranty information booklet provided in the vehicle glove box
    for details. Should you encounter any problem with your Volvo, simply
    contact the nearest Volvo retailer for assistance.

    I believe that the USA standard for emission related parts, like the ECU,
    unlike the abs controller (sorry) is 10 yrs/100,000 miles...

    Why should the people who brought the world GW Bush get a additional year of
    coverage, and 80k KM of coverage might be another argument. Best you will
    get from the dealer is a better price on the part and YOU pay for
    labor....if Volvo gets involved you might get the part free, but I will be
    very surprised if you get free labor.

    Best of luck!

    Well, thanks very much to all who replied.
    I feel a bit stupid but at least I know why this car doesn't smell of
    wet cement like my 850.
    The car went into the dealer yesterday and it was the throttle module
    that had failed(spot on Mike), so they changed it.I have been on a 200
    mile round trip today and the engine was very smooth with cruise working
    They are looking for £515 in total for the job but the service manager
    is going to contact Volvo to see if they are prepared to contribute. He
    wasn't very hopeful as it is such a common fault they actually keep the
    module in stock. Which brings me back to my original post, it does not
    seem right to me that a car of this "quality" should have this kind of
    expensive fault after what I consider to be a relatively short life.
    Lets face it you might have second thoughts about buying one if you knew
    you would be faced with 500 plus quid bill to replace none moving parts
    after 60k miles.
    Thanks once again to all, and if I don't get a satisfactory response
    from Volvo perhaps everyone should be made aware of what they consider
    to be good enough.

    If it is acknowledged as a common fault I'd say that strengthens your
    case for a contribution. Manufacturers do commonly pay out for known
    issues, even out of warranty. Land Rover replaced the dashboard lots
    of Discoverys (including my own), often well after warranty expired as
    it was known to be a common fault (and also glaringly obvious, so
    perhaps generating more corporate embarrassment).

    Good luck (I'm looking forward to mine failing now!)...

  11. I agree 100% with what Tim says here. In the USA, for example, VW is buying
    loads of folks new coils due to faulty ones installed in the factory--the VW
    dealer kept those parts in stock!

    GM recalled every Saturn (a BS us only line I believe) SUV because the rear
    suspension breaks, yes the control are breaks!

    In the USA after the dealer there is the 'zone' which is part of the dealer
    network run by the builder. If the dealer denies your claim ask for the
    name of the zone rep.

    Good luck, Andy!

    $1000 for a module on a 4 year old car--its Robin Hood with a 21C twist--
    rob from the people and gives to the rich!

    I have to report that Volvo have agreed to contribute 50% towards the
    cost of the module, thus reducing my bill from £515 to £270. Perhaps not
    as much as I would have liked, but better than nothing. It just goes to
    show, it's always worth asking.
    Thanks to everyone
    Best Wishes

    The Coil pack problem is well documented here in the UK- they've been
    failing pretty much since VAG started using them on the 4, 6 and
    occasionally 8 cylinder engines. Its cost them millions. It doesnt seem like
    the new ones are totally reliable either- these have been failing too!

    The 4cylinder 20v turbo applications and V6 2.4 seem most affected.
