E280 saloon 1998 reg.( auto - advantgarde) 126 K mileage. "Oil sensor malfunction" Above warning appears infrequently (about four times in the last 6 months) Each time I check the oil level which is always at maximum. Is it an expensive job to remedy ? Can I forget it, as long as I check oil level regularly? Merc. agents will not discuss the problem they just say book it in for investigation. £80 per hour !!
