For anyone interested,
I was told by my volvo main dealer that the ICM was faulty and needed replacing at a cost of........£850>>>>>aaagh
Bought one from a salvage yard,fitted it and it works perfectly,no coding ,no software download,
Personally think that main dealers mislead people on purpose.
PS unit from salvage yard was £100
Hope this helps anyone
ICM unit can affect certain dash functions,in my case the dashboard itself suffered intermittent power loss,no speedo etc.
not suer how volvo justify £850 for a part that must cost them nowhere near this,and is easy to fit.
