That was indeed a lot of debris. Nice to get that removed!Cleaning and fettling my new acquisition 2007 2.0l Z4, suspected front scuttle drains were slow to drain so took the wipers and scuttle off to reveal years of debris build up, took the opportunity to check the rear of the wiper motor for grease contamination on the electrical contact plate whilst I had it all out.
I hope you didn’t keep the floor jack out there for too long. Left my tools out once in rain, didn’t properly dry and spent entire Saturday removing the rust lol.
