MOT Brake test. What happens?

[QuattroFever]

Hi all, not good news

Had my MOT done a couple of weeks back and he done a handbrake brake test on the rollers.

What damage might this have caused?

Center Diff. Rear Diff. Or both??

I am getting skipping and scrubbing through corners when on full lock at slow speed. and grinding when going fast round a long sweeping corner. Kinda like the diff. lock is on but not as bad and I'm getting quite a bit of road noise.

Mine skips and scuffs through low speed, full lock corners too - i thought that was normal for a quattro

Could be. I never noticed it before though?

Could just be paranoia. The fact that he's done it is making me pick at things I wouldn't normally have noticed???

I don't know how easy they are to damage.
