Hi, as a newbie to mercs I would like some help in identifying an engine part. It is a silver box with cooling fins on it. It sits on the top near the bulkhead and kind of in between the red plastic 'v' of the cover. It is making a quite loud ticking noise. any help would be appreciated...
 
Post a pic, as you know the saying
 
I think that’s the engine control module housing.
 
Hi Wolfie1, I cant post it as it says file too large
 
Mmmmm ticking box - MB timed bomb for when warranty ends
 
thanks guys, It cant be that making the ticking type noise then - wont be any moving parts in it. Looks like a trip to the dealer stealers :(
 
Injectors tick - well external ones do.
Changes with engine speed - easily identified.
 
only seems to happen after engine has warmed up
