Hi. The vw alarms are not bypassable.

must be on right timing in all pulleys and gears on mark then remove it

Hi. Check the oil level, and if it is too high (overfull) then please take the car into a dealership. RegardsNeil

this is a turn in caliper, meaning that as you try to compress the piston, you also need to rotate it clockwise. you can buy tool for this at nearly any parts store, and is fairly inexpensive.
