Help! S80 ABS Pump motor control - £1200 to £1500?!

[Arnold Layne]

Had my "ABS/DSTC Service Required" fault codes read today. (It's a 2008 S80 D5 Auto).

The fault is:
BCM-C00201C ABS Pump Motor Control - General Electrical Failures - Curcuit voltage out of range.

Independent Volvo specialist tells me that they have to replace the entire ABS Unit, at the following cost:
New ABS Unit (from Volvo) around (at least) £1000 + VAT
Approx 2 hours labour £110 + VAT
Software Approx £45 + VAT

I don't remember if the entire ABS Unit needs replacing or the Entire ABS Pump Unit, but I think it was the former. Forgive my forgetfulness, I was in shock.

Independent claims he might be able to source a used one through a breakers yard at less cost, but that would only offer 3 months warranty, and of course the risk that it could pack up at any time.

Apparently for this car the entire unit must be replaced, unlike V50's and S40's he tells me.

Help please, am I being fleeced? Any help at all gratefully appreciated.
