my first post here goes
purchased a ml270 2001 122k
noticed even just on idle slight soot from exhaust and when accelerating away puf of black smoke but then clears untill you go on boost again
full history but was due a service so i carried out oil,oil filter,air filter changed the maf as old one looked like it had seen better days removed egr gave it a clean as was gunked with crap
put it all back together and its..... the same lol still soot on boost and idle made no differnce
now on driving it with the windows open i heard what sounds like a huge boost leak so bonnet open to look again i can see the injector closest to the bulk head seems wet around it was not pouring just seems like it might have a small leak somewhere and ive had a nose around the intercooler pipes but could find no leaks but im sure i can hear one as driven many high performance turbo'd cars and hated boost leaks
anyone got any suggestions about where to look for the boost leak and about this weaping injector or maybe know why its sooting the smell from the exhaust is definatly unburnt fuel as its foul
any advise would be apriciated
