The only way I could see this as reasonable for a dealer is if they are working on a current model (not applicable in this case) or just happen to have another equivalent JK on the lot at the time.
Agreed.
Let’s do the math here:
Remove MY sensor - labor
Remove TEST sensor - labor
Install TEST sensor - labor
Remove TEST sensor - labor
Reinstall MY sensor (or a new one) - labor
Reinstall TEST sensor - labor
As compared to remove MY sensor and replace with a NEW sensor.
Their approach isn’t without merit to diagnose the problem, it’s just labor intensive and can they literally just remove a sensor from another vehicle, try it in a vehicle that could damage said sensor, then return it to the donor vehicle?
I wouldn’t allow them to use my vehicle as a troubleshooting tool for someone else’s issue.
They should be able to remove the sensor in question and test it.
The kicker here is that I challenged the service manager on this and he said “Since it only takes a few minutes to pull and swap a sensor, this is a very reasonable approach.”
I then asked him “If it only takes a few minutes, why do you charge a full hour to replace one?”
