Yes the CSC is a very common fault on the 370. Just got mine back yesterday after it failed on me after 24000 miles. In the US some are trying to get a major court case ( or something along those lines) going against Nissan for the crap they send out as a CSC. Apparently the Oem CSC is a piece of crap with major flaws .
Just read about the Oil gallery gasket on the pre 2012 370s ... Please for the love of god don't let that be my next problem í ½í¸í ½í¸
