    Here's a daft question for the panel :doh:

    On my S124, the engine undertray was damaged over the Christmas period and removed. It has never had a gearbox undertray in my ownership (or if so it was removed by someone and never refitted).

    Since then, I've sourced both undertrays and I'm having them fitted next week.

    Given that the exposed bits will have been covered in muck and salt, should I get the underside cleaned before I get the undertrays fitted and, if so, how? Or am I just being stupid and should just get them fitted?

    A careful steam clean or jet wash up on a ramp might be a good idea but not essential. The undertrays on the diesel models formed part of a sound capsule and the front section contributes to underbody aerodynamics. If its any consolation most rusting doesn't take place a very cold temperatures [ its a thermodynamic mediated reaction] so if you remove the bulk of any corrosive residues now you should be fine
