I am just doing the B service on my Hymer MLI 580, I am astonished that they manage t get away with the way it is designed, and put together. Mercedes are as bad as Hymer. Just the little things like to get the fuel filter means the air filter must be taken apart in the engine compartment as ther is no room to remove it complete through the (letterbox) that Hymer allow as access, even the two halves are a squeeze, under that is the cover on the engine to come out to gain access to the fuel filter which is a complete arms length from the front. but doable oil filter is OK but the nightmare of trying to fill the engine oil through the rubber tube they supply. it is 4 inches too short and you cannot get a jug to the inlet as the front panel and scuttle stop you getting it in there, OK so pull the tube as it is rubber then it kinks at the bottom so the oil doesn't go in or down the tube, 12 litres needed in the engine. Underneath I need to drain remove the sump of the gearbox to change the filter and oil for the auto gearbox. Difficult to get the oil out as it leaves 5 litres in there after the sump plug is out and the stand tube removed. Then you drop the pan with another 5 litres still in it, the problem is there are two cross-members that are closer together than the length of the actual sump pan with the oil still in it. I wore a load of the oil after it splashed out over me.
It seems MB modified the shape of the pan by another inch at rear end just too much to go through the gap they allow.
The fluid change has been brought back from unlimited mileage to the B service and now is part of the A service, however at 32000 miles it is like new and clear green but not at all dirty, At the Dealers they want £450 to change the fluid in the gearbox only, hence I did it for £150 instead.
All these silly design faults make it a little clearer why the MB dealers staff run for the door when they see a Hymer and probably the other MH makes coming in for service. The new gasket and needed for the pan and the one I have is wrong along with the filter they supplied, I need to go back on Monday to get the correct ones. I wonder how much they actually do for their service plan or just stamp the service book.
I know I probably will never buy another motorhome, but if I did it would not be an 'A' class model. Everything that is done in the engine compartment is a real pain so god help you if major work needs doing on any type of 'A' class model.
I will rant again on Monday after I find what else there is to catch me out when I try and finish it.
