Took my X7 for the Spanish equivalent of the MOT yesterday. Passed ok with no advisories. However, as I drove off the rolling road after the brake test (passed fine) I noticed that the brake servo doesn't appear to be working any more after the severe braking test. Very hard brake pedal now. I didn't say anything, got my pass certificate and left the test centre. The question is, how the heck can a brake test wreck the servo? As far as I'm aware there's nothing electrical in the system to blow a fuse, just a mechanical vacuum pump driving the servo. Ideas anyone?
Isn't it fun owning an X7? Never know what's going to pack in next!
