ABS pump fault - 01276

The fault appeared after the car had been stood a month over Christmas, the battery had been removed (for charging). I am thinking abs sensor (should I say hoping) has dirt/rust on it.

Car is a 51 2001 Octavia VRs

Wounded if any one out there has had this fault and can tell me what to look for. I have found the info below and will be trying out some of the solutions suggested.
