This just started yesterday. I've seen a few other threads about lurching in 1st gear with the F1 gearbox and they all say it's operator error. However I've been driving this car for 5 years and this happened for the first time yesterday. It's definitely a mechanical fault. Starting from a stop, the car will lurch like it's having a hard time engaging. If I gently let the F1 ease into gear then it will go without any problems. The other gears all seem fine. Also...with the car sat in the garage and turned off, when I select between N and 1st, the normal click of the actuator is now accompanied by a mechanical whirring or slight "grinding" sound that never used to be there. The car hasn't been in for it's annual yet this year, so I'm hoping this is just related to fluids or something. A few weeks ago the clutch was measured at 79% remaining. F1 issues make me nervous ($$$). Any ideas on what might be going on?
