#58 of 64 2004 V70 Headlight Issue
Jul 20, 2011 (12:14 pm)
Hi everyone! I have had my v70 for nearly a year and recently I've been experiencing some headlight failure on the driver's side. I have the uber expensive Bi-Xenon bulb kits so this is posing a bit of a problem for me. The bulb and wiring are fine on the non-working headlight (I have a private mechanic who works on the car) but he has informed me that the ballast is shot. I understand that getting a ballast from the dealer is going to be exceedingly expensive (somewhere in the neighborhood of $600) and a used one isn't very reliable. This predicament brings me to my ultimate question: would it be more cost effective to just switch the headlights to Halogens? If so, is the procedure simple and what components would be involved? Are there extra parts needed to make the switch successful? I have been researching this, but it has been to no avail. I am trying to avoid paying $200 for ONE Xexon box. Thoughts?
Thanks so much!

I had the same exact thing happen Thursday, 7/21, I'm told it's my SIMs card. It's going to cost between $1500-1800 for replacement. I've been told that this happens in hot weather. It started last week and I had the computer rebooted, but given that it didn't last and we're having a heat wave I decided to get it replaced.

So this has been a saga with me. The first time I had this issue, I took it to the Volvo dealership near work. They took everything appart and cleaned and reset all the electrical connections into the CEM (Central Electronic Module). Labour for this cost about $800. It seemed to rectify the problem and it worked for about 12 months. This past June (the 9th), the exact same issue reappeared. I took it to the Volvo dealership closer to my home, and they identified it as the DIM (driver information module). They cleaned and reset the DIM and it seem fixed (for $400). This past Thursday (July 21st) it happened again....so after $1200 in work its still acting up. I talked it over with the head of service, we ran further diagnostics, and we have replaced the CEM ($1360). I am crossing my fingers that this soap opera is done.

Simply order an HID kit from China with Aliexpress. I have done many conversions using these kits. They are cheap and have given me no troubles. You should be able to select a kit with bulbs that match the OEM bulbs and use the ballasts that come with the kit. Possibly order the ballasts alone.

I hope your problem is fixed. If not, I understand that whilst replacing the CEM, the dealer must also rewire the the cabling to CEM and install a new shield that cover the cabling. This is located under the wiper motor, so you need to take out the scuttle panel to check if the modification has been done.
This was a recall / modification bullitin issues by Volvo
Hope that help.

I have a 2003 v70 wagon (loaded, with winter package)-almost 100K miles - For no apparent reason, the fuel/temp gauges move back and forth, all dash lights disappear, the digital clock speeds ahead, the "no seatbelt" chime starts, the doors start to unlock and lock repeatedly, interior turn signal lights fail to come on, but the signals still work on the exterior (thank goodness!) - cig lighter dead as a door nail (fuse is good) - starter issues occasionally - will give a little click and nothing happens - I have to take the key out several times and restart and then she will come around. Is there hope for another 50K miles with this vehicle (our second and LAST Volvo product due to the lack of integrity of the service staff)? Or should I make her a DNR? Thanks for any suggestions or feedback. Pam
