What happened to your D3/D4 today?
After a minor car park incident I partially popped off part of the LH front wheel arch surround. As it would not pop back on I determined to learn how to remove it.
The only trick is having to remove the headlight to access a small retaining screw you need to undo from the inside. The rest is obvious plugs and screws inside the wheel arch. A tiny screwdriver needed to get the one in front of tyre without taking tyre off (or start off with wheels turned). I used a driver in a 1/4” socket. Then it will pop off easily bit by bit and lift out as there’s a T piece that locates in the very front lowest point.
Glad I did this as I found the entire circumference of the inside guard full of 12 years of leaves and the plastic surround packed with muddy beach sand in the lower corners. This is all part of the drains under the bonnet that siphon leaves into them.
Found also one of the bumper bar cover screws had rattled out and was sitting loose inside the guard. Gave everything a nip up.
Pulled off the RH side which was even more full of said leaves and sand. Takes less than 5 minutes with practice.
P.S. a cheese knife with a forked end makes a wonderful trim tool for removing the plastic lock plugs in the wheel arch.
Definitely a worthwhile maintenance activity to program one day you are on the front lawn washing your car as handy to have a hose on hand. Rears to do next.
