Hi,
Over the past week or so, I've had a C150 (No communication to DME) PSM fault appear a few times. The dash says PSM failure, and it's OK after a restart.
It only appears after about 1 hour or so. Then today, I had a 3 hour drive back home and it happened after about 1 hour, but then was fine again after restarting. Then later on, I went over a seam (usual bang!) and the whole dash lit up, all things failed, spoiler, PSM, oil temp, water temp and all the dials just going up and down.
Again, it cleared after a restart, and didn't come back.
I had the rear carpets out last weekend, and it was a bit wet under there, I think from the rear wiper grommet getting loose. That's been cleaned, gummy pfleg'd and put back and no more condensation which is good - the condensation only seemed recent so hopefully it was caught quickly. But would it be plausible that the rear carpets behind the seats are still damp, and when warming up causing the humidity to break some of the circuits in the ECU / DME back there?
I'll get it all out and leave it to dry but wondered if that seems like the right cause? Or there could be something else?
