2003 s60 2.5t traction control warning flashes
 

Hi everyone i have a volvo s60 2.5t and the traction control warning flashes and engine loses power when cornering right, goes back to normal when straight no problem when cornering left,slight noise from front left wheel bearing.any idas could this be connected. .

You could do with with getting the codes read. Sounds as though it could be a near side abs sensor fault. Check the abs ring on the half shaft as well. These rust and crack over time throwing the sensor. TBH though, my experience with these isn't connected with cornering.

Do you have DSTC button at the bottom of the center console ?
When you drive in a straight line, is the steering wheel perfectly centered ?

Otherwise may want to verify the axle center bolt is tight and there's no cracks (even tiny) anywhere on the front axles reluctor rings

My 2006 d5 does this when turning left, think I’ve got both the steering wheel clock spring and possibly a sensor or reluctor ring crack as a few times today the brake pedal was kicking back with ABS pulses when slow manoeuvring
