As suspected, they hadn't tightened the sump plug enough. There's a nice puddle of oil in front of the dealer where they parked my car before I collected it last week

. I've been assured they swapped the crush washer for a new one when they fixed it
I had a terrible buying experience with Toyota Gatwick but they changed hands so thought I'd give them another chance.. impossible to get through to service dept without calling repeatedly for an hour. I've never had them call me back a I always have to call again and finally they left me with a dangerous car for what must be the most basic error in car maintenance.
Hilariously was offered max £200 off my
next service
with them. I agree the service should be free but after some arguing settled for £200 refund now rather than go through protracted complaints procedure.
Any dealers with a good reputation in the south east I could use in future? Independent is tempting but in case I don't keep the car long term I want the resale value of Toyota service stamps and it has to go to them after 3 years for warranty anyway.
Now its back I've got some focals to install, a sound generator to unplug and to find somewhere to paint the wheels dark bronze
