This LandRover discovery was recovered to us for diagnostics due to low power under 3000 rpm. We quickly got to work and found the following fault codes p140a and p132b the p140a related to the egr valve the most cost effective solution for the tdv6 is to disable the egr valve in the vehicles software, once disabled the egr does not function and no further egr faults will occur. The next fault is p132b this relates to the turbo actuator, the tdv6 engine has an electronic turbo actuator the is prone to failure over time the solution is to attempt to free the stuck turbo actuator and confirming the actuator is moving correctly.
