Mercedes Benz ML270 CDI

Hi Spino, to get the injector, it is important to have "a little patience"; Retrieve the injectors in their order, start the engine and put it to heat, clean if you can the injector area in the cylinder head to remove carbon (if it has there), see "WD 40" or other fine oil, when the engine is already hot, (lained flange) give some accelerates and for the engine. With the hot engine already, the ravus and with a key, toured the injector (even side and other, see oil) let the oil penetrate and then turn the injector again, without hitting or forcing, if it already turns a little, see trying to leverage and turn until you take it out (it has already worked for me twice this method) sometimes it is necessary to let it rest the oil one day and repeat the day breaking it .. patience and luck !!!

(Some light "blows" in the singing of the key, even side and other, will make the carbon layer on the injector wall, to penetrate the oil ...) but with "touch" ... not to get nervous, ok? If necessary, remove the coil to be able to put a "star" key, that will give more grip and avoid deteriorating the nut plane
