By crap e63 on
2007 Mercedes-Benz E-Class E63 AMG 4dr Sedan (6.2L 8cyl 7A)
Car now has 10,000 miles. Has been at the shop 5 times. 3 check engine lights. I get same brake problem that everyone else has a problem with. Engine knocks and was told this is my problem due to California does not sell 93 octane gas. Rough starting in the morning. I have contact the dealer manager he tells me don't bother until the car has 12,000 miles. Mercedes direct says you have to get these issues resolved with the dealer. Has spent a total of 28 days at the dealer. Buy a M5.
