Re: Mercedes CLK 200 1.8 cc 2003 Archived Message Posted by Andrew Ruellan on October 10, 2007, 6:56 am, in reply to "Re: Mercedes CLK 200 1.8 cc 2003" This car has the newer M271 engine. These have a problem with valve guides that causes misfires.(carbon fouling of exhaust valve stems)This was fixed from engine number 677947. Your engine number is 129523!. You need to do a compression test. They also suffer from split breather pipes under the air-box. (hard to see!) Re-flash of the control unit (then SCN coding) is also an option to cure uneven running on these. I have sent one of these back to the dealer for "goodwill warranty" recently . They are fitting exchange heads. What is the mileage? More to follow when I have time Message Thread: Mercedes CLK 200 1.8 cc 2003 - Dominic Casey October 9, 2007, 5:20 pm Re: Mercedes CLK 200 1.8 cc 2003 - Peter Lomas October 9, 2007, 7:49 pm Re: Mercedes CLK 200 1.8 cc 2003 - Paul Whatmough October 9, 2007, 9:37 pm Re: Mercedes CLK 200 1.8 cc 2003 - Nige Cowie October 9, 2007, 11:19 pm Re: Mercedes CLK 200 1.8 cc 2003 - Kevin Apps October 9, 2007, 11:22 pm Re: Mercedes CLK 200 1.8 cc 2003 - Kevin Apps October 9, 2007, 11:25 pm Re: Mercedes CLK 200 1.8 cc 2003 - Peter Lomas October 9, 2007, 11:58 pm Re: Mercedes CLK 200 1.8 cc 2003 - Andrew Ruellan October 10, 2007, 6:56 am Re: Mercedes CLK 200 1.8 cc 2003 - Joe McGeoghan October 10, 2007, 7:35 am Re: Mercedes CLK 200 1.8 cc 2003 - Michael Whitworth October 10, 2007, 7:43 am Re: Mercedes CLK 200 1.8 cc 2003 - Tony Ludford October 10, 2007, 8:37 am Re: Mercedes CLK 200 1.8 cc 2003 - Dominic Casey October 10, 2007, 10:00 am Re: Mercedes CLK 200 1.8 cc 2003 - Kevin Apps October 10, 2007, 8:03 pm Re: Mercedes CLK 200 1.8 cc 2003 - Nigel Bennett October 10, 2007, 11:02 pm Re: Mercedes CLK 200 1.8 cc 2003 - Kevin Apps October 10, 2007, 7:52 pm Re: Mercedes CLK 200 1.8 cc 2003 - Andrew Ruellan October 10, 2007, 9:18 pm Re: Mercedes CLK 200 1.8 cc 2003 - Tony Sefton October 10, 2007, 10:07 pm Re: Mercedes CLK 200 1.8 cc 2003 - Kevin Apps October 10, 2007, 10:49 pm re:merc clk200 2007 service light - alan thompson July 24, 2008, 8:23 am Re: re:merc clk200 2007 service light - Bryan Smith July 24, 2008, 12:55 pm Re: re:merc clk200 2007 service light - UKAT1604 July 28, 2008, 9:55 am
