Volkswagen Polo Power Steering Fault

Another common diagnostic job in the workshop at at the moment. The very
popular 2014 VW Polo R-line, in for a power steering fault.
Symptoms are – power steering light on and no operation from the power steering.
Fault codes present were 00816 – Power Steering Sensor (G250) after some
further tests on the power steering pump we confirmed that all  of the relevant power feeds and earth conections
were present. Also the CAN-BUS communication data was checked with the oscilloscope, to confirm that the
engine control unit and the power steering pump were communicating.
 
Once all of this was confirmed the pump its self was condemned. New one
fitted and the problem was sorted! Another successful VW diagnosed and repaired in Ulverston
