Had intermittent indicator issues too. Removed the switch and disassembled it and cleaned the contacts -- now it works perfectly!
Try this first save yourself some $$$. It's easy to do, after the switch is out, carefully remove the screw that holds the circuit board in place. Watch for the moving parts that will want to pop out. Turn the board over and you'll probably find lots of wear where the contacts move along the board. Clean this. Re-install.
Contrary to the VADIS instructions I found my switch had a plastic flange which prevented putting in back in perfectly straight. If you have trouble with this like I did, shave the flange off with a stanley knife. It's Volvo over-engineering.
