240D heater core leaking
 

I started taking the car apart to get to the heater core eather I am missing somthing or some engineer was a real idiot when they designed this car and how they put in the heater core.It apears you have to tearr apart the whole heater controls and a bunch of wiring to get to the core.This one steams up the windows when you turn on the defroster.I was thinking a can of supersealer before tearing any more apart.

Try the leakseal and hope it works. To remove the heater core you must remove the center consol, the dash and the heater box. Which then must be seperated to get to the heater core.
