Here's a new one...Start Button Fault
Spent the day at COTA turning several tanks of fuel into brake dust and tire shavings.
At the end of the day, after last session was complete, stopped on pit lane to pack up my stuff. Car would not restart. Message on display was
Start Button Fault - Call McLaren Service Center
Windows were down and ebrake was on. Car was VERY hot, having just come off of track on a high 80-degree day. Center console was also very hot, with the sun directly on it.
Tried lots of ways to reset it. Walk away/sleep/reawaken...OBD scan tool Reset All Codes...disconnect/reconnect battery...no dice. Thought I was going to have to leave the car on pit lane overnight with the windows down.
Texts to service personnel at both Houston and Philly (Thanks for the weekend support, guys!) revealed "never seen that one before".
Eventually was able to get the windows up by repeatedly pushing the Start button while holding the window switch up. Didn't work on the ebrake, though.
Finally was able to power-up by sitting in car with both doors closed, and then locking/unlocking. That reset something and the car started. Drove it to garage, turned off and tried to restart. Fault reappeared. Was able to repeat the lock/unlock sequence to start again, but clearly something is amiss.
Anybody ever seen this one before?
