Just got the car back from the dealer in St Louis. Total repair cost to me, including both the throttle control unit and the MAF, $124.00. Turns out that the aftermarket service contract folks decided to cover it, except for the $50 deductible and some clamps, and other small parts. Haven't added it up yet, but just scanning the bill, the parts would have been about eight hundred bucks (however, they give you a box of candy to eat on your way home--cost is hidden in the "miscellaneous shop overhead" item). If I can manage to have another 4-5 hundred in covered repairs before the service contract runs out, it'll have paid for itself.
BTW, the dealer pitched my IPD throughpass gas cap, claiming it was one source of codes (possible, tho it's been on the car for three years now); I checked the IPD site and they now have a warning not to use that cap on '99 and later cars( just below a long story about how well it worked on a V70). Now to see how much of the $400 tow bill (120 miles at $3/mile, plus $40 hook fee) I can get reimbursed by my insurance company. Meantime, I'm gonna be nice to my old truck--never know when it's going to be needed because the S70 is down with Dutch elm disease or Belgian waffle syndrome or some damned thing.

All the replies are appreciated. There are no volvo shops, indy or otherwise, within 125 miles--just shipped it off to Brentwood Volvo on a flatbed; I don't even want to contemplate what the tow bill is going to be, much less the cost of repair. I'll also find out just how much the aftermarket extended service agreement they sold me is worth.

Take the car to a Volvo dealer as they have to replace the ETM and reload software into the new unit. If you try replacing it yourself or have it done elsewhere, the car won't run until new dealer only software is DLd into it.

I feel your pain. You are part of an ever-expanding group that no one wants to be associated with. Check out my post from about a week ago. The exact same thing happened with my 2000 V70/XC. I hate to break it to you, but depending on where in the country you live, you are looking at a $900 to $1100 repair that can ONLY be done at the dealer. The reason is that they not only replace the defective throttle control module, but they also download new software into your car's brain and no indy has it.

You can also check out my and other posts about this on www.volvoxc.com under the 1997-2000 forum. It is truly unbelievable. I urge you to call Volvo of North America and log a complaint, the more people that do, the more likely they are to step up to the plate and do the right thing.

Their number is 800-458-1552

Still hoppin' mad
