Inside the boot is a plastic cap embeded in the boot liner. Remove the cap to reveal a screw. Undo the screw and the whole rear light cluster will come away in a sideways and not rearward direction to reveal all of the bulbs. Hope this helps.

1) The Electrical panel on the side has a black bar that is the mounting bracket. It is only clipped in place on the plastic outer casing. the black metal bar is attached with 2 shoulder screws. these probably just worked themself loose nad dropped out. Go to your dealer parts counter and ask them for the 2 screws. Remount the black bracket and then re clip the case to the bar.

This is the correct solution..........replace the solenoid valve N239 as the electrical connection is affected by dampness. What happens is that the EGR valve is jammed open by the solenoid and this allows oxygen starved air into the cylinders (exhaust gas) and combustion is poor.
Quick fix is to disconnect the vac hose to the EGR actuator and block the end with a self tapping screw or pencil. This will work for sure....
