I have recently discovered an oil leak on the auto gearbox in my n54 335i. I am led to believe it is from the mechatronic sleeve. I will replace the bottom sump and gasket whilst performing this work. However, does anyone know somewhere in the uk these parts can be bought apart from bmw??
Any help would be greatly appreciated. And I will hopefulky put up a diy for the mechatronic sleeve change when I get time to do it
