Hi I have a Ducato based motor home, it is a 2022 2.2 Multijet 140, Collected it from the motorhome dealer and on the way home after 40 miles, max oil level warning came on. It does not have a dip stick so I was unable to check the level, when we got home drained the oil and filled back up with correct amount , maybe 0,5 litre to much oil. The oil warning has not reset, I have taken it for a short drive to warm it up and re-check but message has not reset. Has any one had this problem and know how to reset the message?
I would expect this is be quite a common fault with pretty much any new vehicle brought today . Now before i start i should explain that my vehicle does not have this stuff , and i won't have that does one given to me , but then i am of an age , where i can get away with saying this . I do however , drive modern trucks every day , and i'm talking about heavy trucks , up to and including 40 tonners . In the early days , when this type of vehicles first appeared , drivers would fill the oil as normal , and this warning would be prolific . This was enough to off road the vehicle , whats know as a VOR (Vehicle Off Road) in the trade . Speaking to a mechanic to try to find an answer as to why , i was told never to fill any more than half way between the lower and higher marks . This did actually cure the problem , and it's a rare occurrence to have this warning today . But personally , i find this answer ridiculous .
Now this was quite a few years ago , but in those days we did still have a dip stick , so it was fairly easy to avoid . Nowadays you literally have to tilt the cab to do a manual check , and so is more important than ever . I can't tell you how to clear the fault on dash , as those affected vehicles would be taken off line , to the workshop . When they came back , they would have what i call a clear panel (no faults) . A local mechanic told me , that modern electronics will actually clear a fault by itself after a set number of cycles , but whether this includes the oil i really can't say . Another note i make , is when you checked the level , i trust you did let the vehicle stand . In my experience only one check is possible a day , and that's when the engine is cold . Once the engine is turned over , oil pressure increases and an oil check often fails . Try checking again in the morning . Failing that my advice would be to return the vehicle to a Fiat main dealer . Sorry i know this will be expensive , but get them to sort it out . I have been told that manufacturers have realised they are missing a trick . Once they sell a vehicle , they don't make anymore money on it , and this is certainly the case with mine . Over the last 3 years , i have spent somewhere between 5 , and 7 grand bringing my vehicle up to scratch , not one penny has gone to a dealer . This is why modern vehicles are difficult to work on , they don't want owners fiddling . Now i don't know if that's true or not , but i have noticed some rather unusual things are breaking . So on that note , maybe you can perhaps begin to understand , why i hold the view i do . They are just more trouble than their worth .
So , just as a foot note , only this last week , i had a warning to check the oil on an 18 tonner . As usual no level showed on the dash check , just check the oil . I've learnt to gingerly put a litre in the sump and recheck . This revealed the level was okay , yet I still had no level check . The result is i still have no idea how much oil is in the sump , just that the level is okay .
Not really an answer , i'm fully aware . But maybe with a little extra knowledge from someone who has been through something very similar , it will give you an idea of how best to advance . I can't really offer any direct advice of how i would progress , as this basically would go against all my knowledge of engines , and with a motor as new as you have , this must be something you , and only you can decide yourself .
