2008 S550 ESP INOPERABLE

I went through a car wash, and the ESP Inoperable popped on, did not reset with turning car off/on.

I have read through the posts, but have a few more questions.

Tire pressure is at 30lbs, could this be causing it? It normally is around 35 to 36 after driving, but it is low (I dont drive the car that often). I need to put air in it, clearly. Both front are evenly low (30lbs each).

Could a sensor have been knocked loose on the wheel in the car wash..doubt it but a though...

Any insight would be great, i really prefer not to have to take it for a replacement unless it is necessary.

Thanks for everything as always.

Regards,

...my mechanic (who is the shop foreman at the local dealership) said it very likely could be a speed sensor, and they dont look very expensive to replace
