Fault

A graphite impeller within the vacuum pump fails causing vehicle faults.

Sometimes water ingress can cause problems with these pumps, often however the impeller on the spindle of the motor can break or shatter over time. 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.

Common associated fault codes:
B1436-012, B1436-014, B1436-015, B1436-016, B1436-017, B1437, B1438-011, B1438-012, B1440, B1442-012, B1442-015, B1442-016, B1442-017, B1442-018.

Solution

Install our replacement impeller and restore your vacuum pump

Dealers will try to sell you a complete new PSE pump at great expense (£900+), but our solution simply replaces the component part that has failed; the motor impeller. This repair with our replacement graphite impeller wheel and new fins will get your pump back to full working order at a fraction of the cost. Our parts are made of an improved Graphite material. Replace just the component that fails, avoid the cost of a whole new PSE pump assembly that would just fail again. Install of our new component is straight forward please check out our instructions and video.
