Hi
I had a problem with my W205 220cdi 2 injectors were leaking and there was a build up of carbon which was bad, I replaced the rocker cover cleaned all injectors and the shafts. Put 4 new merc seals and bolts and was fine for a month or two. one injector started leaking again so I took it out cleaned it up. Brought another seal and stretch bolt from merc dealer fitted the injector and was fine for a month or so and started leaking again. Can anyone assist me with an answer ?

Thanks in advance Paul

My advise to you is to stop waisting your money. This a serious problem: the injector is leaking. Let your local dealer check it and let them fix it once for all. If the same problem came back again the dealer must fix it for free.

replace the injector!

think if i replace the injector it will leak again as the injector is working fine but its like the seal fails and starts leaking wondering if its the thread in the stretch bolts

its not leaking fuel the seal fails and carbon leaks
