QuestionWe are unable to find the cause of a water leak under the car; leak is seen on the ground just below the area between the windshield and the back of the front tires slightly to the right of center. Water contains antifreeze. No hoses are defective.
AnswerWhich E320 do you have?
E 320 Sedan
E 320 Cabriolet
E 320 Wagon
E 320 Coupe
What you describe is a leak in the false bulkhead trough area = further diagnosis needed.
Possible:
* Heater hoses. I hope it is a hose...
* Heater core.
Trace the heater feed hoses to the false bulkhead trough area, disassemble as needed for access.
If you DIY, I suggest you get the factory service manual on CD for $19.99 from MBUSA.
