Oil pressure Wandering
MY2006 C2S 52K miles. My car has been pretty reliable except for the odd CEL. Durametric indicates misfire on 4-5-6 at cold start occasionally. My engine is pretty quiet (no unusual clicks clacks or noises. After the car emerged from the garage following a few month stay due to traveling. I noticed the oil pressure doing something weird. With the engine warm, oil capacity full, sitting still at idle, The oil pressure will randomly wander from about 2 Bar to 2.2 then down to 1.8 etc randomly, then back to 1.5? It never falls below 1.5 (normal idle for this car is 1.5 when fully warm) but just seems to move around, randomly, leisurely. A Durametric test of the cluster shows no anomalies. No other codes. Anyone have any ideas? Similar experience?

I had the same issue on my 4s and was quite worried until I found many other posts of bad sending units etc where the needle tends to "wander". Mine was running between 1.5 bar and 4.5 bar and anything in between. Replaced the unit and back to stable pressure readings.
