Hey guys, I hadn’t really planned on rejoining the P80 group unless it was an R, but a buddy of mine clued me to this “lovely” project S70 base model with 111k. Guess I need to start a build thread once my son and I start working on it!

I know my VIDA/DiCE won’t work since it’s a ‘98, so what are those of you who own this MY using for a code reader? I have an old BSR PPC 3 Diagnostic Code Reader that read/cleared the initial CEL, but interestingly couldn’t reset the SRI. Might have just been a glitch, but I’m heading out of town and won’t have time to check it for a couple of weeks. Thanks!

(Yes, I will update my sig with the new addition. Just haven’t the time to run through all the details yet. Also still working on a name — “POS 70” sort of fits for the moment! )

the 850 OBD app is probably the most powerful tool you can get that is easy to acquire and set up. Would recommend. Vol-FCR and VST are probably more powerful but one is difficult to set up and the other is impossible to find. Other than that any decent OBD code reader is as good as any other.

Thanks, Jared! Will probably start peppering you and Scottish over the next few weeks now that I’m back home and will have a chance to dig into this one a bit.

It’s leaking ps fluid pretty regularly so I’m sure the seals (at a minimum) are blown — found an empty container of Penzoil ps fluid and stop leak under the seat; I doubt a full flush & replace with ATF will be enough even with new seals, but once it has sufficient ATF it steers normally so maybe it’s just the reservoir and/or pump. If I need to swap out the rack, will a V70’s work? There’s a ‘99 in the local jy I might be able to pull.

88domer, the P80s are the best!
That 99 will be good, just the 98 engine uses a distributor and the 99 and up is a Coil On Plug, other minor differences but.. Snag it!
For clearing and reading OBD2 codes, regular $20 reader from Walmart can see most modules (not many show you individual modules, just "Read Codes/Erase Codes")
Maybe one of the modules the $20 Walmart reader can see is the SRS, won't know until you try it..
You have a sedan!! Nice!
Welcome to the P80 club!

Thanks, Volvo Convert. Glad to be back in a P80, just really hadn’t planned on it being via the lowest end of the spectrum. Probably just as well though, as my kids will be driving it mostly — not sure I’d trust my almost-18yo son with an R!!

Jared, I thought about the rack on FCP, but that’s just a little over Benjamin shy of what I paid for this gem, so trying to stay as cheap as possible. As much as I would like to bring worthy Bricks back to stage 0, this one’s always going to be on the opposite end of the spectrum of yours, Scottish, ZZZZZZZ, Shamak, et al. But once we take care of the (hopefully) relatively minor issues it will remain a great college car - hideous to look at, yet solid mechanically.

Sorry, I should have been clearer. I didn’t have an SRS code, and my BSR ppc3 scanner can read/clear the codes it has/had. It’s the service reminder indicator (SRI) that I can’t clear. I wasn’t aware of the uniqueness of the ‘98 in that regard. Will probably do what others have joked about as the solution — electrical tape over the offending light!

EDIT: I forgot to mention that I already tried to reset the SRI by holding the trip odometer reset and turning the ignition to pos II until it stops flashing. No luck.)

the real life differences you'll experience dealing with a MY97-98 x70 vs a OBDII 850 are negligible

The ‘98 Service light can only be reset with a Volvo tool. I was lucky enough to find the AST5408 tool on eBay six yrs ago for $25.
