C230 kompressor engine oil7/27/2023 ![]() ![]() ![]() ![]() While rival BMW M developed the SMG-II automated manual for the BMW M3, the C32 and SLK32 have a 5-speed automatic transmission's "Speedshift" system which now has quicker response (up to 35 percent) to accelerator and shift selector movements. Compared to the standard M112 engine, the AMG version also has a new crankshaft, new con rods and pistons, an oil pump with a 70-percent increased capacity, lightweight camshafts, and stiffer valve springs for a redline of 6200 rpm, an increase of 200 rpm. The supercharger was developed in conjunction with IHI and features Teflon-coated rotors producing overall boost of 14.5 psi (1 bar). The engine is a special version of the 3.2 L (3199 cc) M112 E32, fitted with a helical twin-screw supercharger and water-to-air intercooler. Powertrain consists of AMG SPEEDSHIFT black series 5-speed automatic transmission mated to an AMG 3.2 liter V6 Kompressor engine with an output of 260 kW/349 hp and 332 lb⋅ft (450 N⋅m) 4,400 rpm. However, the supercharged inline-four engine was considered to be coarse and noisy at the high end. The C 230 SportCoupé was powered by a 2.3-litre supercharged, four-cylinder motor. In 2003, Mercedes-Benz added the C 180 Kompressor, followed by the C 200 compressor in 2003-2007 (187 hp), and finally the C 160 Kompressor in 2005. Initial engine options comprised the C 180 (139 PS), C220 (143 PS), C 200 Kompressor, and C 230 Kompressor. The newer 1.8-litre was less powerful but smoother and more efficient than the older 2.3-litre engine 141 kW (192 PS) compared to 142 kW (193 PS). The C 230 Kompressor variant sported 142 kW (190 hp). All of them used the same 1.8-litre engine, with different designations according to horsepower levels, including a version powered by natural gas. In 2002 for the 2003 model year, a new family of supercharged four cylinder engines, dubbed M271, debuted for the entire C-Class range. No issues since last update - still running strong.A Mercedes-Benz S 55 AMG (W220), the only iteration of the S-Class offered with KompressorĪpplications 230 1.8L I4 Kompressor Update October 2016: Just turned 68K miles. 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.
