I have an 06 mercedes e class 320 cdi sport it has done 123000 miles and been serviced . In jan it broke down and would not start , just before this it started smoking very badly whitey grey smoke five mins after it had been idling. It was diagnosed as an injector stuck open creating an air lock... One other injector is getting close to being out of limits but is not out of limits ... The car has a puff of the same colour smoke for a second as soon as it fires , then nothing when it drives although on the first acceleration of any drive it struggles like an old car in the wrong gear ... No smoking at any point when it drives And then when it idles after 5 mins smokes extremely bad whitey grey then clears a few mins after you pull away again ... The Mercedes star computer shows no faults and it's already cost me over 1000.00 and the fault is still there... It did at one point show intermittent egr. Alve but I dont think it's there now ... Could it be the injector that's close to limits ? Don't seem to be getting any where and spending a fortune... Please help !!! Regards glyn
