2007 E350 Spark Plugs
Getting ready to change the plugs.
My question is do you really need the 17mm offset wrench "special tool" to get the wires off the plugs or will a set of regular plug wire pliers do the job?
EDIT:
Never mind. Seems the 3.5 uses coil on plug and the tool was for the older 3.2 engine.

I need to do the plugs on my '08 E350 (M272.985 CGI engine), but easy it isn't!
I have big hands, and access to some of the Torx screws to get the coils off is almost impossible. Added to which, there is a metal pipe on the right (seen from the driver's seat) side of the engine obscuring access to the plugs.
It's a *****...

I can SEE the little barstewards, but actually getting a Torx bit on the ratchet driver into the screws is very tight.
The CGI V6 does not have the plug cap and coil all in one; each coil has a lead to its individual plug. If I try to use plug wire pliers to get the caps off, what's the risk of damaging the leads? Does anyone know what the MB special tool for getting the plug cap off the plug looks like?
(Thinks: I should have stuck to something with an M113 - there's LOTS of expertise on those...)

I didn't know we got CGI on the 272 as early as 08, are you US market? I just checked out a 276 CGI motor and damn is that space tight. ECM in the way on the drivers side, air box and other ancillaries on the passenger side. I couldn't get a good pic of that rats nest. May the force be with you!

No, it's a standard UK car. Yes, it's as tight as a very tight thing...
I'll have a good feel around at the back of the engine (as far as I can reach) and see if I can locate the oil leak by feel. I think it's going to be an engine out job to fix it, though.

E350's engine bay is one of the most accessible engine bays I have had the pleasure to work on. There is nothing facing the cabin behind the engine (sans the transmission). Plenty of room on the front and sides (thanks big brother e500) to comfortably fit your hands AND your tools. Super DIY friendly to work on overall.

"There is nothing facing the cabin behind the engine (sans the transmission)".
The transmission is not in the way; the bulkhead is. Does yours have individual coils with plug leads to each cylinder, or the 'all-in-one' coil tower that pushes straight down on to the plug? I presume it's the latter; if so, it's not a CGI.
Believe you me, on the CGI it is very tight at the back between the engine and bulkhead. In front of the engine there is plenty of space; at the sides, not much; at the back, very little.

I didn't post the photo.
My car is a 272.985. The heads - and plug recesses - are not the same as a non-CGI 272. Thinking about it, if the CGI 272 has a similar head set-up to a 276, the easiest way to change the plugs might well be to take off the inlet manifolds...

Guys, one thing that seems to be causing confusion is that we aren't familiar with seeing a direct injected 272 as we did not have those in the US market. His setup is significantly different from what we have.

Do you think you can post a photo or two of your engine bay with the air intake removed? Would be curious to see exactly how it looks.

Will do. FCPEuro's pic above looks very much like my coil setup, so I suspect that the heads on the 272 CGI and the 276 are very similar, though the ancillaries may be a bit different.
