ugh

Yeah, some chavs from the college up the road from me have decided it'd be fun to rip the entire rear wiper arm from the back of my car. All that's left is a hook and the motor, it still moves, but I'm not sure how "attached" the bit left is to said motor - any idea what parts I'm going to...

Got in the car this morning, did a TBA, started driving and noticed the guage won't go higher than 2-5psi. Assumed limp mode but car is boosting strong. Guage goes into vacuum fine. Check hose, looks ok. Dodgy guage? Anyway of testing it? Cheers Dom
