Watched this video of a tech pulling the engine to replace a turbo...pretty interesting.

It is a long, but fairly common procedure as engine mounts which are a common failure require the same procedure.

Very cool nevertheless. Every time I see the v12 drop out without a snag it brings a smile

The motor mount replacement requires the engine drop?

WHPH28

I'm glad I have a warranty too!

if you have kids' hands you might be able to do it on the s600. i have seen such magic pulled off lol..

the v12 amg motor requires engine out both for the s and sl class motor mounts

is it only for v12 biturbo?
or does it also apply to v6/v8 biturbo?

to be honest- have not seen the v8 biturbo out of a car yet nor have been a witness of any engine mounts go bad on those. so i dont know.

On my 2008 S65 I was charge 6.5 hours (at the local dealership) to replace motor and transmission mounts with no charge for coolant etc that would be related to removing the engine. So, somebody has figured out how to replace mounts with removing the engine. I do think the WIS shows around 25 hours labor though (could be wrong). Total charge including parts was $1,303.25.

Very interesting video. I replaced the engine mounts on my V12TT last year. I didn't move the engine - just supported it and dropped the subframe. I also replaced all the ABC pipes at the same time.

That allowed me to keep all the oil, water, air, fuel, HVAC, ABC and electrical interfaces connected, which saves a great deal of work (and risk). No need to even remove the cold air intakes.

Its still a difficult job, as access to the left upper forward engine mount bolt is blocked by the AC compressor. A high quality E-torx ratchet wrench may help.

Changing the engine mounts was actually a "while I'm at it" activity, as I rebuilt both turbos. The right hand side one was leaking oil and smoking, so I removed and rebuilt both. The turbo rebuild kits, ABC pipes and motor mounts totalled about £400.
