The handbrake adjuster is under the centre console behind the lever. If its coming too high, check that the levers at the rear brake calipers are free and moving back to their stop position - they are prone to seizing up on older or little used cars. They can usually be freed off with a bit of lube and working the lever back and forwards. If that dosn't work, unfortunately you'll need new calipers. Do not adjust the handbrake cable unless the caliper levers are at their stops as this seriously reduces handbrake efficiency!
SOURCE: VOLVO S40 VVT VALVE
Very easy to swap the vvt valve,but that will not guarantee to rectify the problem,more than likely it will be the vvt pulley/timing unit,this will involve the timing belt coming off.
The vvt valve is located under the upper timing cover,remove the cover and you will see the valve situated on top of the head,undo the connector and remove the 4 bolts and the valve will come off,alittle bit of oil will come out on removal.
remove gasket and ensure the area is clean.
Re-fitting is opposite procedure,ensure a new gasket is fitted.
Hope this helps
