Hi everyone. Hoping someone can maybe suggest a fix for my problem. I have a 51 plate A4 2.5 V6 Tdi which has recently started to lose power. It started off only losing power very occasionally and usually in 6th gear. The problem has now got much worse in that it does not seem to have any power at all now (occasionally the power comes back in short blasts). I have had it in at my local Audi garage who could not find any problems with it. I have had it looked at by an Audi specialist who has given me the fault codes but is not keen to take on the job as they're not sure what's wrong with it. The car also will not rev over 3000rpm. The following are the faults which came up: <ul type="square"> [*]00575 - Intake Manifold Pressure - 11-10 Control Limit not Reached - Intermittent [*]18062 - P1654 - 16 - 10 - Signal Outside Specifications - Intermittent [*]00519 - Intake Manifold Pressure Sensor (G71) - 31-10 - Open or Short to Ground - Intermittent [*]01039 - Coolant Temperature Sensor (G2) - 30-10 - Open or short to Plus - Intermittent [/list] Has anyone heard of this or something similar before. Any help would be greatly appreciated as it's no fun to drive now that it has about the same power as my Mondeo TD!
