[urq] Center diff lock

[Maurits Jonkergouw]

Lately my center diff lock is getting engaged on agressive accelerations, mainly above 80 mph. The diff indicator light goes on briefly and you can feel and hear this very loud thumping noise from the back end, very scary. 

This happened many times now and I'm afraid I ruined something. 

It's like there is too much vacuum and this actuates the switch or something.

It's the 'later' style diff lock system with one rotary switch and two lights.

Any thouhts?
