ive got complete service records and receipts but they are all in japanese from BMW japan.one of them says "head gaskets"in handwritten english at the top of the receipt.i cant imagine them doing head gaskets without doing intake gaskets which i want to rule out as a probable cause of rough idle when cold.anyway if anyone can interperit ill scan and attach the receipts to this thread.thanks

If the dealer did it, There should be a record/Receipt for every gasket that was in the way of getting to the Heads.

Yes i am japanese. Send me a copy and i will translate it for you.

ill post the receipts tomorrow,and yes there does seem to be a looooong list of parts on the receipt that appears to be head gaskets.
