Service Engine Soon Light = $1330 repair? HELP!

[96ce]

I have a 2001 X5 4.4 that has been a pleasure to own and essentially trouble free. Recently the SES light came on so I took the car to our local BMW dealer. The codes were P1160 and P2190. On Friday the dealer advised me that "the PCV system needs to be replaced as hoses and systems became soft and collapse when engine is running. Appears to be be due to engine not being used enough to remove condensation in the engine oil system". The estimate to repair is $1,330!!. I am shocked. My X5 has 24,000 miles which I know is low for a 2001, but I never heard of such an issue. Can anyone shed some light on this topic? Is the estimate appropriate? I would greatly appreciate any insights / advice, and also would appreciate a recommendation of an independent BMW shop in the central NJ area ( I am in Princeton). Thanks folks.
