HELP! Battery died now car will not start...dealer stumped S70 1999

Battery drained by open trunk over three days. At starting, dash lights on but engine makes only a ticking sound. Dead battery. Closed trunk and connected battery charger/starter. Lights brighter, engine turns over, catches and dies. Immobiliser does not recognize key.

Leave car, lock/unlock with remote. This does NOT clear problem so call dealer who suggests what I had just done, then says battery not charged enough to maintain required voltage so must leave car on charger for three hours then repeat. Follow instructions; no joy.

Have car hauled to dealer. They cannot start so push into bay (on Wednesday noon). I wait. Problem? "Do you have your other keys/fob with you. Computer detects immobiliser problem and either you have a bad computer or a bad key chip. Need other keys to confirm." Drop off all keys/fobs 0630 Thursday. They call office to confirm failure of computer. They need to order: computer module, two software sets, three new keys. They need to charge for: five hours diagnostics, one hour labour. Parts will be in on Friday (I'll be out of town) and I can therefore pick it up on Monday.

Arrive home Saturday night to phone message from dealer. "Volvo will not send the parts without further diagnostics to confirm exact problem and reason for failure. They will be contacting us on Monday to offer tech support. Your car cannot be ready before Tuesday at the earliest."

Has anyone already suffered through this particular pain and offer me the correct solution to pass on to the dealer. This car is no longer under warranty and hence the labour cost is becoming worrisome.

    Resolved. Yes I DO have a Volvo battery.

    Volvo Tech Support agreed with the dealer what the problem was (security computer module failure) but required additional diagnostics to determine the reason for the failure. I did not pay extra for the additional research, but Volvo came up empty and could not determine the cause.

    Duration: from noon Wednesday to end of business Monday.

    Determination: Security computer module failure.

    Reason: unknown

    Repair: 1 module, 2 software sets, 3 new keys, 5 hours labour diagnostics 1 hour labour repair, total cost with taxes was 1145.00 Cdn

    Follow-up: Since the repair the car operates as expected. Found the radio had experienced security shut down. Reentered radio security code and it now operates but was surprised that the dealer would not have taken care of this while they had it. Because of the discharge/recharge of the battery I did a check of fluid level and discovered that it was necessary to add nearly 3 cups of distilled water. Given the problem that the car was towed to the dealer to correct, I was again surprised that this had not been reviewed by the dealer.

    My expectations are too high.

    Do you have a Volvo Battery? If so this may be the problem. The Volvo battery is known to last about three years and then goes out. I had mine replace under warranty at three years, the warranty battery lasted about two and half years.

    Apparently the parts that they're trying to order need to be released from Volvos tech support hot line and they must feel that they need more diagnostic info from the tech trying to get the parts for your car. Unfortunately, there's nothing that you or anyone here can do to help speed up the process.
    Todays newer Volvos can have some strange electrical problems and fixing them is not always easy or fun for anyone. All I can say is "be patient".
