I noticed my brake booster vacuum pump has been clicking on and off alot, especially when first started. Is this normal? The brake pedal is a little grabby and stiff, maybe there is a leak? How would I go about testing for this? I did a VAGCOM test and there are no error codes and the pump works on demand so I doubt it is a pump issue. Is there a pressure sensor that can go bad etc??
