Coolant life
What is the expected change interval for coolant on 2009 e320 bluetec?
I heard that the extend life is due in part by an anti-oxidant puck in the reservoir. What are the part numbers for the coolant and puck?

The fluid is dark blue. So the whole reservoir and coolant need replacing after 15 years or a coolant leak? By another 7 years the prices should come down.
Thanks at all respondents

My year 2008 manual does not actually say anything about reservoir replacement:
"US Service 8 at every 150,000 miles or 15 years
Replace coolant"
(Footnote says: "Service 8 at 150,000 miles or 10 years")
Anyone here who knows if service 8 includes reservoir replacement?
PS. The OEM reservoir price is $52.25 at online store, so it's not so bad if it had to be replaced every 10 or 15 years!
