steve, you were correct. the hose clamp on my fancy reverse intercooler system had come off the intake to the turbo. reattaching the hose solved the running issues. so, the ets light and limp mode were caused by a dying battery, and the surging and crappy running were an induction problem. turns out...

rubbing probably isn’t the right term, neil. more like something spinning. it was engine-rpm related. happened when i depressed the pedal to push the acceleration while driving the car forward. i reved it is park, drive, and neutral without moving to the same effect. as i got to just over 3,000 it s...

well, i got the bus going (about which i ‘ll post in the samba), so time to turn back to the v70 xc. in the interim the battery died. considering the feedback from joshua at xemodex and neil here, i thought, hey, maybe that’s it! replaced the battery. no ets light. started moving forward. no limp mo...

thanks, steve. shifting my focus to getting the bus going so i have at least one running vehicle. joshua at xemodex thinks it’s the ecm cause of the no-response to the key symptom. it has occurred to me that it might have stalled in drive, which i think would explain that. i really don’t remember, b...

thanks, neil.

unless the accelerator pedal position sensor is in the throttle body, right?

more info. got my code reader resurrected long enough to pull codes again. prior 3 codes still there. clarify one of those: 604D, not 6040, so some tex-message info code 3 new codes: 917f 9520 958f all having to do with the accelerator pedal position sensor. went through exemodec's diagnostic tree, ...

icarsoft reader is dying, won’t check volvo codes. but, my notes say 9040, something about ets light, which, yeah, i already know that, i’m checking the codes cause the ets light is on!

thanks for your input, neil. yes, erased the codes, and yes, they returned. the ets light leaves, but comes back. limp mode was worse this last time than previously. all buss contacts look clean and bright. the maf was a bosch from fcp. didn't fix the issue at hand that last time, though can't remem...

meant carfax. damn spell check.
