Newbie XC70 Owner With Electrical Issues

Post by ezbme » Tue Mar 28, 2017 9:02 am

Howdy all,

I am happy to find this incredible source of info for those who obviously have the Volvo "bug". My first Volvo was owned way back in the late 80's, a 1970 142. I loved that car, wish I still had it. Many years have passed and the Volvo has changed immensely since then, but I still have the "bug"!

My wife and I recently picked up a 2004 AWD XC70 Turbo. It is a great running, solid car that is a blast to drive. When we got it there were no warnings on the dash, but that quickly changed, literally within a few days of taking ownership...

We now have a few items that concern me. One, the interior fan continues to run even after removing the key. I ended up pulling the 30a fuse to shut it off as it was killing the battery. No idea why this is happening.

We have a brake failure, stop safely alert. Also the brake light is on along with the ABS light.
I have read others comments on this but with myself being new to the computerized systems, I am lost on all the acronyms and jargon that everyone is using. I am going to buy a code reader shortly as it seems I need to have one but really I have no idea what to buy and how much it will help to have one, much less how to hook it up and use it. I am quick to pick things up but I do need some help, in layman's terminology, just till I get the hang of things.

Also, I now have another error, check engine light is on.

The cruise control stopped working as did the heated seats. The odometer seems to be turning very slowly, or not at all. The speedo works fine tho.

This all is very frustrating but with the price and condition of the car, and the fact we really do like it, we want to get it back to working order.

Any help is appreciated, I look forward to digging in and fixing and checking things off of the list.

The later model Volvos actually have a fan run-on feature but it should go off in a few minutes, not hours.

The ABS issue will probably generate a bunch of other codes, and disable your cruise control, so don't panic - you may only have a single issue from all those 'failures'

Research the code readers before buying - for about $150 you can buy one that will reset SRS and ABS lights which will pay for itself first time - Its about $100 to get this done at the dealer.

Figured I should add a few photos... She is a high mileage girl, about 227k, but really in good shape. Dealer was looking for offers, window sticker was $6,500. LOL, I offered $1,300 and they took it as their lot was jammed with used cars...

Closed the deal at 20% of the price anchor - I might have some products you could sell for me...

Sweet price, however I'd be careful with bringing it back to working order thing. At these miles, several things can happen, better save the money for urgent repairs. Bringing this car to a main dealer will cause the buying deal turn sour and not necessarily fix the issues.

The 2004 had the unfortunate water ingress issue over the CEM but I would check this in the last place. You can google up about these acronyms - such as 'volvo cem' and look for forums. It's not a cheap fix, xmodex does it for about $400. Just I won't rush into replacing things.

For the brake thing, I'd start with the reluctor rings, they may get rusted and crack at some place. The ABS control module may fail but can be split open and resoldered.

The cluster thing can be related to the CEM or to an alternator issue.

I'd leave the cruise control and heated seats at the end.
