Preventative Water Intrusion, Autumn,F01/F06/F10/F11/F12/F13
Discussion
Just a wee warning for everyone of the above, but make sure you check the area around the bonnet struts for leaf debris and also the now infamous "yellow grommit that has holes in" (which is where the LHD steering column goes on the bulkhead and is blocked with a yellow grommit for RHD cars)
You will find that the nearside bonnet drain area connects with the bulkhead yellow grommit drain, and debris collects there. It is worth removing the four T25 bolts of the lower small bulkhead sound dampening panel as many F10/F11 owners have found a plenty of collected dirt here (or in some cases unfortunately found the fact that the yellow grommit has holes in the top or the seal on the grommit has failed following damp rear carpets (the front will initially show no signs of intrusion because of the thickness).
But as per above this particular bulkhead cut out and drain method is seen across all of the above F series cars (and the Wraith, Ghost and Dawn).
