Rover 620 - Honda 2.0ils - ABS problem

I have the Honda version currently with ABS problems. The codes have been read and 1-8 was returned, something to do with 'accumulator gas leaking'.

I believe the best option would be to change the whole unit, which appears to be an 'ALB' with the following stamped on it - D27 9234 F12.

Any info on changing it would be useful:

- Are there any special precautions to take?
- Does the system have to be bled - guess yes - how?
- Anything else anyone can think of.

All contributions will be gratefully received.
