Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

Volvo S40 - Alternator change - ECU reprogramme?

    Hi all,

    Had the Red warning along with the battery indication "power system service urgent" about two years ago. I replaced the alternator myself and it ran fine up until a few days ago.

    I have got the same indications appearing, however if I turn off the ignition and restart a minutes later I might not get the indication at all.

    My question is, if anyone knows if the 2005 Volvo s40 1.8 requires some kind of a software update when replacing a 120amp alternator with a 150amp.

    Thanks.

    Does this alternator have a clutch pulley? If so, it could be your problem

    Wont get a chance to remove alternator until Monday. I'll check that also.
    I'm just surprised that I've gone through two alternators in the space of 2 years.

    Cheers.

    Took the alternator off today, seems the b+ cable (alternator to battery cable) is fairly frayed and brittle.

    Am looking online to see if I can source one.

    If anyone knows any good sites for Volvo parts can you post a link.

    Thanks.

    Good spot with the cable - hopefully that's all that's wrong. A good auto electrical house should be able to make a cable up for you?
