Do you know anything about DSC faults on the BMW 3 Series?

I wonder if you have had any requests for help about the DSC warnings displayed on BMW dashboards? I have a 55-plate 3 Series and have only ever used the DSC once, in the bad snow at the beginning of this year for a couple of hours. Out of the blue a couple of months ago, the DSC warning light came on and stayed on, so I took the car to an independent BMW specialist. They ran a test and gave me a piece of paper with the following fault code printed on it: '5E20 Hydraulic unit: pressure sensor, internal'.

They advised me this was a common fault which had been around for years. They had had three cars that week with the same problem. They advised me to go to a BMW dealership where they knew BMW rectified the fault for free on cars younger than '05 and, where appropriate, either replaced the unit or had a kit which could mend the fault without having to replace everything. Do you know anything about this?
