What are some 2004 mercedes clk320 problems?

Mercedes-Benz vehicles are typically known for not only their luxury, but also their reliability. While the 2004CLK320 isn't without its problems, they typically occur at a lower frequency than one would expect. Top reported issues are oil leaks, a broken stepper motor causing clicking noises, and crankshaft position sensor failure. Depending on the cause and location of oil leaks, this may be Your simplest or most difficult fix. Another common issue to watch out for -- the CLK320 requires the use of premium unleaded gasoline, because of the engine's superior compression ratio.

Be sure You don't fall into this trap.
