Parking Brake/Auto Hold - issue on B7?

[Paulq]

I have a 61 plate 2.0 TDi BM SE and the auto hold has started to play up a bit. The Parking Brake also feels like it will not hold properly on inclines. I had read that these were a issue on the B6 but what about the B7?

Are they fixable or a time bomb?

Thanks.
