The US model, labeled C 230 Kompressor, became available for the 2002 model year with the M111.981 engine, a 1.8 -liter supercharged inline-four making 143 kW (192 hp) at 5500 rpm and 280 N⋅m (210 lb⋅ft) at 2500–4800 rpm. Mercedes-Benz debuted a coupe variant in October 2000 (launching in 2001), labelled the C-Class SportCoupé and given the internal designation CL203 (see below). There was a version of this car that was made in Korea. Six-speed manual gearboxes were now standard for the entire range, except the C 320. The diesels now featured common rail direct fuel injection and variable geometry turbochargers. Most of the engines were carried over from the W202, but the C 320 was exclusive, offering 160 kW (218 PS). The sedan debuted with a range of inline-four and V6 petrol engines and inline-four and -five diesels. The second generation C-Class was unveiled on March 21, 2000, going on sale starting in September 2000. Testing began in 1997, with development concluding in 2000. Design patents were filed on 20 April 1998 and 4 March 1999. Cheers.Design work on the W203 C-Class began in mid-1994, with the final design being approved in December 1995 by the executive board. Runs great and code is gone! I hope this helps people in the future. I cleared the codes and went for a long test drive. I do not understand WHY the clogged ports effects the idle. I put everything back together and started the car up. Once the ports were all clear, I pulled the spark plugs, cleaned them, and cranked over the motor with the plugs out to make sure I did not hydrolock the motor. DO NOT let this WURTH cleaner get into the exhaust pipe as it will ruin the convertor. and kept going till I could spray the solvent into each exhaust port and watch it flow out of the hole in the head. Sprayed it into the holes, let soak for hours sprayed in compressed air and did it again. It has passage ways inside the head that goes to all 4 cylinders. I removed the Exhaust manifold and tried to blow compressed air into the metal pipe that bolts to the head under the exhaust manifold. I removed it and the metal pipe going to it was clogged THE ports in the head were also clogged. It's on the right side of the motor above the Exhaust manifold. I asked around, friends and different mechanics regarding this, but nobody really knows how to deal with it, but instead I'm getting a "if it runs alright, why would you care, just drive it like that" but that's far from a solution, which I'm after.Īny help on that matter will be appreciated.įIXED FIXED FIXED!!!! YEAH!!!! NEW UPADTE!! Problem FIXED!! The thing that I thought was a EGR valve was actually the Secondary Air Injection valve. I wasn't able to find any information on the internet regarding the whole air injection system, and all of the components, what I could find are simply little bits and peaces here and there, but nothing specific that could give me a better understanding of the whole situation. I'm wondering if this could somehow be related to a bad/clogged EGR valve too? Should I try removing it and cleaning it first before digging deeper into the system, or it has nothing to do with it? I searched the around for this problem, but all I could find was information regarding a problem with the secondary air pump, which is not the cause in my case, because as far as I'm aware, the pre-facelift w204 models with the M271 don't need that pump, but instead, the supercharger itself is doing the work, therefore, there is no secondary air injection pump. So far I checked and changed all of the air pressure hoses from the EGR valve, to the air intake solenoid located under the engine cover, I visually inspected the rest of the hoses around the engine but I didn't see any noticeable cracks on them, at lest from what I can see without removing the air box assembly and/or the supercharger unit(kompressor) So I'm having this issue with makes my check engine to light up every now and then outputting this error code P0491 which to my understanding is related to the secondary air injection system on bank 1(whatever it means, I guess cylinder 1)
