i think it could be a contrbuiting factor in the problems i've been having with my boost being pretty irratic,i've had this problem since i've owned the car and whilst systamatically trying all other avenues of trouble shooting i.e, ecu check replacing det sensor,leak tests , turbo rebuild,etc,whilst checking wiring under bonnet i've noticed when my boost only goes to .5 bar, if i wiggle the alarm wires that i get my boost back....
