breaders

Hello all,

I have a warning light and beeping, upon reading the codes I got the following error message,

c3472 a7/3y11 left rear axel solenoid valve (release)

History of work on the vehicle recently are:
failed alternator - replaced with bosch original
Replaced both batteries- previous owner drove it and charged it for too long unfortunately.
replaced fille nozzle, so i could have disturbed the two electrical cables going to the right rear hub.

Anyway, new batteries and cleared the low voltage error messages,
But still have this rear solenoid error.
rear the rt sensors with an MB2 code reader, seems to be working ok.

So, the question. where can i find the solenoid valve?

has any one come across this before and any ideas if i can repair the valve if it is sticky.
