![]() ![]() First fitted to the CLS350 CGI, it produces 292 PS (215 kW 288 bhp) and 365 N⋅m (269 lb⋅ft) of torque while lowering fuel consumption. A direct injected variant debuted in 2006 under the name Stratified-Charged Gasoline Injection (CGI). Also tumble flaps are used to improve output at low engine speeds. New electronic coolant flow control has replaced the mechanical thermostat for improved engine warm-up and optimum control of engine temperature. The twin spark plug system was replaced by a regular single spark plug per cylinder. Featured on both the intake and exhaust camshafts, each can be varied through a range of 40 degrees. A dual-length Variable Length Intake Manifold is fitted to optimize engine flexibility.Ĭontinuous VVT was adopted for the first time. This essentially eliminates first and second order moments. Like the M112, a balance shaft is installed in the engine block between the cylinder banks to deal with vibrations in the 90 degree V6 design. All have forged steel connecting rods, one-piece cast crankshaft, iron-coated aluminum pistons and a magnesium intake manifold. The aluminum DOHC cylinder heads have 4 valves per cylinder.

So far, I have not had need to use the extended warranty. I discovered a small crack in one of the rear wheels which was replaced with one I purchased used online. I serviced front and rear brakes (purchased OEM parts online) - a relatively straightforward job. I performed routine maintenance and inspections since the CEL issues I had shortly after I purchased the car. Update April 2016: Overall I have been pleased with this car. Expensive (over $2K), but warranty covered all but $150. Still running strong although I did use the extended warranty last year. Overall a positive experience.Īn update: Car now has 72,000 miles on it. In the five years I drove it, the only major repairs were what I described previously. The rear end damage was extensive enough for the insurance company to declare it totaled. Update 10/6/19: In the spring of this year the car was hit while parked in a lot. ![]() Recently purchased an extended warranty - just in case. Since then, the car has run nicely - although I do get high speed vibration on certain stretches of highway (probably due the the low profile tires). A month later a coolant pipe began leaking at the rear of the cylinder head (I replaced this myself). ![]() The 1.8L engine had a cam sensor design flaw which leaked oil into the harness (cam sensor seals were replaced under a MB recall by previous owner, but not the oil saturated harness). Within a month the CEL came on and required a new engine harness and two O2 sensors to repair. I purchased this 2004 C230 Sedan Sport one year ago with about 56K miles on it. ![]()
