This is for a 2003 540i, ~100K miles. They haven't opened up the car yet to see if the flywheel can be resurfaced or not but this is what they quoted me for the parts cost of the flywheel. Looking online with the same part number: 21-20-1-223-581 I'm seeing prices of USD 1300 for OEM. Is this the same part that BMW uses? Are they ripping me off? Can I say something to them about the cost (never done this before).
