MOT tomorrow so spent some quality time under the Elgrand.
Bodged the fog light back on, cableties ahoy! and cleaned out the corrosion so that it works
replaced a rear 501 sidelight that had gone out with a very cheap and dodgy led one
replaced both serpentine belts on the front of the engine, changed the oil and filter and the air filter (blueprint filters and mannol 5w30, no idea if this is frowned upon or not)
refitted the undertray thats been off for a few months for... reasons.
welded up various exhaust holes, replaced a gasket at one of the rear cats, broke a bolt, drilled it out, fun.
replaced the crappy dash graphic thing with a decent one, all crisp and new looking now!
Best thing: discovered the rear heater system - there's a whole heater system back there guys!
worst thing: discovered emulsion in the coolant and under the oil filler cap
looks like it's head gasket time.
