ive actually had the same message come up, where there is an oil symbol and it says hi and beeps. this was bout like 3 weeks back when the weather in jersey was like round 76 degrees and my engine was runnin at 80c. it was actually the irst time i have seen this message since i got the car(jan, when the oil was just changed) its only been 2k miles since and has 58k miles on it, its a 1999 c280. its quite odd b/c it did that/beeped like 3 times that day, and then 30 mins later it never happened. never happened since that day, i figure its a ghost.
sorry i couldnt figure out the problem, it think the temp might be high, thats the only thing i could think of.
