Oil level sensor failure message
Temperatures have ranged between -5 and -10 degrees over the past week here. My 156 20V sportwagon has been holding her own not too baddly in the snow and cold. (Brera virtually unusable!). However, had to charge the battery for the first time ever in the 156 yesterday morning, which was fine - car started up again as normal. Went out yesterday evening and display read OIL LEVEL SENSOR FAILURE - GO TO DEALER etc and showed the dashed oil level indicator as 'empty'. I immediately checked the oil, which seemed ok (maybe a little low) car went for timing belt and service at 69k 3 weeks ago, so oil is fresh and should be at the right level. Any idea whats happening - is this an electronic failure, frozen sensor or 'real' oil level problem? Have done a couple of quick forum searches but can't see anything similar.
