10 minutes preventive maintenance on an E63 / 64 6 series
Discussion
Hi all ,
I left my car for 3 days at the airport last week when we had torrential rain. When I opened the door and flipped the seat forward I was greeted by an inch of water in the rear drivers side foot well, with no sign of how it got there. First thought was blocked drains under the pollen filters. I believe the water level rose over the intake height of the filters and into the heating ducts. Lowest exit points of the ventilation system are the vents under the front seats.
It has been a couple of years since I changed the pollen filters and cleaned all the leaves and muck from under the filters, so the procedure is:
Pop the bonnet, there are two pollen filters, one located on each side inboard of the bonnet hinges.
You will need a 13mm socket to rotate the single plastic nut through 90 degrees, then push the retaining wire off the pollen filter case. Note: the driver’s side has a couple of wires, so go gently. Lift the pollen cases out of the way. Below is what I was confronted with (this is the passenger side, the driver’s side was worse). Drain was close to being completely blocked (buried under the leaves and mud on the right hand side). The hole on the left is the entry point for the ventilation system.
There is a small plastic fillet which sits on top of the drain (already removed in the pictures, which just pops out easily), to reveal the top of the drain funnel.
Clean out the leaves and flush out the crud, then gave it a wipe down. Replace plastic fillet and replace pollen filter covers.
Job took 10 minutes from start to finish. This is now an activity I will do annually.
Cheers
