Hi everyone, think I'm going to need some help over the coming months, just starting a project labour of love with a 300c diesel. Relatively good condition. But I think it has been taxi'd it's a 2007 with 200,000 on the clock. Mot history shows one big fail, brakes suspension steering related. Wheel bearings all replaced. No mention of emissions at all. Looks like it's been looked after, no advisories. Question, which other model of car uses the Mercedes-Benz OM642 engine? I've heard essentially it's a sprinter engine with a big turbo whacked on. Please excuse any mis information or ignorance I've displayed. I could buy one all singing and dancing but that's not my way, I like to put the time and effort in myself. I have big plans for the car so any help would be appreciated. Thanks in advance Stevie
