Year of Manufacture *: 2008 ( Optional ) Engine Code or CC: 2179cc
I have a customer with the above, display shows "transmission fault traction reduced", checked and found fault code P1889 Oil pressure pump performance in rear axle module.
I have checked power supplies / ground to module and checked for continuity in oil pump which appears to be open circuit - has anyone had any experience of this system (which I believe is similar to the Audi one).
Should i have a path through the motor which would indicate a normal permanent magnet motor ?
Checked the workshop manual but it just explains the system and how to remove components, no test data
