Description:

SYMPTOMS OF FAULT: Central locking not unlocking doors, boot not popping open, lumber supports in seats not operating, soft close boot not working. You can hear vacuum pump motor working but nothing is happening. THE FAULT: A graphite impeller within the vacuum pump fails. A broken impeller will cause a lack of air pressure/ vacuum to be provided meaning actions of the PSE pump will be inhibited. It can also lead to a jammed motor which will lead to the pump blowing the 20A fuse and shutting off.
