With the MOT due at the end of the week and about two months worth of dirt and salt accumulated I've spent this morning with all four wheels off pressure washing underneath and all the nooks and crannies and i noticed that just behind the shock absorbers on the front there a really nasty little recess that seems to sit behind the main body member, I've never noticed it before but i must have cleaned about a mug full of crud out of it.
Anyone else ever noticed this and has it ever caused problems on Mk2 panda's?

I've seen that too and was wondering the same.
As long as it gets washed when you wash the car it should be OK I think.
I am planning to use some Dynax S50 in the spring/summer.

Take care what you point a pressure washer at as great damage can be done as the water can be forced into places where it should not go.
