08 2.5 Repeated failing of Exhaust pressure sensor - Andrew Moorey (Tune-Up)
I am investigating a problem with fleet of around 160 of these vehicles from 06 to 08 reg typical mileage between 120-200k. The exhaust gas pressure sensors are repeatedly failing due to ingress of condensation. VW are no help but it is a known, common, problem. I have to try and get around this problem and wonder if anyone else may have found a solution ie vapour traps in the sensor pipes?

How do you knoiw it's a condensation problem? Is the condensation getting into the exhaust side of the snsor, or the atmospheric side?

If it's condensation on the exhaust side of the sensor, can the sensor be isolated from the exhaust gas by a thin diphragm? Such that the pressure fluctutaions can still be sensed, but, no moisture can pass?
