OIL LEAK GETTING WORSE. THE MECHANIC MENTIONED THAT IT WAS COMING FROM THE VALVE COVER GASKET, HAD THEM REPLACE IT 2000- STILL LEAKING OIL, BUT NOW FROM THE REAR INTAKE GASKET. i AM EXTREMELY DISAPPOINTED IN mbz
had this happen last year, oil leak got progressively worse, major repair since the engine has to be taken apart to get to it, cost me $3,500 to repair the leaking seal on this thing... the oil pressure switch and the oil level sender have also leaked, $300 each.

My check engine light turned on and my car went into limp mode, or what I thought was limp mode. This was cylinders 7-12 shutting down. I figured it to be transmission issues. I took it to the shop and the diagnosis was the oil cooler is failing and it had a leak also. It's a 28 hour job and will cost $4,000-4,500 to fix it. I don't know if the car (S600) is worth it to repair though.
Oil cooler leak. Heads removed. $500 fix 3 years ago. Now 74000 miles on car and appears to have recurred. Mercedes refused to make good on repair on last leak at 52000 miles, but did pick up 10% of the bill. My $4500 cost was after the 10% discount.
