Hi new member but long time user for the great advice people give on the here for Mercedes having owned a few .Anyway my problem and hopefully someone can help me is my Van has a misfire when it is cold for about a minute it has been like this since i have owned it about a year it has full Mercedes service history and has done 140,000 .Its just been in for a dual mass clutch and fly wheel plus a new water pump.So far the garage have tested the compression,glow plugs,glow plug relay,injector values whist running ,no fault codes show up on the star machine i am wondering whether anyone else on here has experienced the same .I took it to another garage who specialize in sprinters and vitos they said that all the 651 cdi engines do it but surly this can not be the case any advise would be much appreciated thanks
