Opinions needed asap on ass

I have my car in for service. I have coded the ass to be off when starting the car as it's real annoying, rough and activates when not supposed to (like when I'm doing low speed maneuvers such as parking the car in my garage).



So question is should I let them take a look at it, the most likely answer being a software update. I would assume then I will lose all my coding.



So for something I'm unlikely to use should I even bother?
