RPM/Shift flares

Post by Nathan79 » Fri Aug 09, 2019 8:27 am

Daily Driver 07 Xc70, 175k symptoms: Driving (keeping rpms under 2500) shifts wonderful, zero issues.
However when getting RPM'S get between 2500/3000 there is a RPM flare, & if Throttle maintains its position the RPM flare will repeat until throttle position is changed... Somewhere in the neighborhood of 300-1000 RPMs flare
When driving (from a stop or already cruising doesn't matter) and throttle is "pressed with conviction" and RPMS get to 3000-3500 before shifting...sounds rowdy and I'm off to the races.
No codes ever... Been driving it this way for about 10k miles...Not getting worse OR better.
Also worth mentioning...ABS module is out, no brake power boost, odometer not functioning (but will momentarily show that its working upon startup sometimes)

Things I've done so far(after symptoms started): tranny fluid flush & b4 servo piston swap. *Charging system tested good... However I'm not sure if it was tested under 3000 rpm load.

Thanks for any help
Nathan

Try taking a look at the throttle boy. Maybe give it a cleaning.

I've read on a website with reviews that the throttle body on these late 2007-2009 S60 may have problems (not the same as early 01-02)
Not saying is sure. Maybe ask Xemodex guys, see if they are aware of such issues.
If you go that way, maybe try getting a used one from the junk yard - not sure about programming/compatibility
