Finally sorted my rear washer as it stopped working a while back, got the rear boot trim off and it was dry as a bone! Followed the pipe to the passengers side trim just above the boot light and found the joint had popped out. Refitted, taped, dried the damp interior out and cleaned out the fairly horrid substance growing in there.
Also sorted the coolant temp sensor going off in the cold mornings, just cleaned the sensor prongs in the coolant reservoir and it's been mint since! Cleaned and hoovered my interior, back to black'd all my plastics and slapped a new air freshener in. Productive day!
