Make that 2.65 and you've got a deal. In other words, the same as mine.
And is your car a N A vehicle for here or a European addition?

Sorry if I was out of line.
Simply wish I knew more and could afford your hot rod. Fine machinery to say the least.
Many do not understand how much better your car is than the later E-63s.
Especially where you live at your altitudes. There is nothing like a
turbocharged or supercharged engine in the mountains.
Look at what that Econo engine in that Lincoln did during that run above the Eisenhower tunnel.

You are right is 2.65 and is NA, in EU some are 2.47 and other are 2.65 (both with ring gear diameter 210mm and 45 teeth on the ring gear and 17 on the pinion gear) there is also 2.87 with same diameter and gear teeth numbers. I am not sure if taller final gear will hold up to the torque.
Your tires have 4.8% error resulting in speed increase, why you are running them, on stock tires I am 65MPH/1900RPM and you do 65/2000 or more precisely 66.6/2000???

Taller tires for less revs

27 inches in diameter and turn 769 revs per mile.
I went to these 215 X 65 -16s to try and gear it higher so
it would not be revving as much at higher speeds on the highway.
I had these tires left over from the Jetta TDI, so when
the noisy Michelins wore out, I put them on.
The Continentals are lighter in weight and much quieter also.
And being lighter and a little bit narrower plus being LRR,
I think my highway fuel economy is better.
So 2.65 X 0.83 X 769 equals 1691.4 revs per mile or at 60 mph.
So 70 mph should be 1973 rpms. My tack reads 2000 at 69-70 mph
according to my GPS. I figured approx. a 4 % decrease in revs
because of the these taller tires.
They rub slightly in the front with full lock turns, but the taller tires
are only rubbing the fender liners, and not causing any harm.
As you may know, the speedometer gets it readings from the right front wheel.
With the taller tires, the speedometer reads only 66 mph at 69-70 true speed.
The odometer is short by exactly four (4) percent whereas
it was dead accurate with the 225 X 55 -16 Michelins.
Wish I had the European 2.47 gears. As you know, we have the
and if fifth gear with that rear end ratio (overall 2.0501) were
not enough, fourth or direct drive (overall 2.47) would be!
Exhaust with no mufflers is a little loud at 80 mph (2255 rpms)
so I either cruise above or below that point.

Update on progress - Nearly there!!
The 'thread doctor' has been and completed the rethread/resleeve and overseen the installation and torquing of the new injector clamp stretch bolts. BTW no new clamps were needed just stretch bolts and injector seal washers. The garage have advised after speaking to the 'thread doctor' that the pipe that attaches to the first injector had a kink in it after it blew out, so although they have bent it back they recommend replacing it as it is a weak point and creates a potential pressure point as the pipe is slightly crimped.
Shouldn't be too long now till I am back on the road now and with the total bill coming in at +/- £550 for every thing the warranty company are more than 'happy' to reimburse me.
Will let you know when I actually have the car back and have had a drive.
Thanks again for all the help so far.

Excellent. Good Show
Recall that I had said that there was no way that the clamp could have broken.
If you were to see one off the car, you would see how stout they really are.
Did you have the 'thread doctor' clean up and replace the
copper washers on cylinders number three and four also?
Isn't it worth the slight extra cost to be sure that all cylinders have new
copper washers and that all new stretch bolts have been installed
correctly by someone that does know what they are doing?
By doing so, you will be sure that those two cylinders will
most likely not cause you any problems in the future.
That is why, when my number three let go and we had already done numbers
one and two about 40k miles ago, that I had the mechanic working
on mine also renew numbers four, five and six.
Ask the 'thread doctor' what he thinks causes this problem to occur.
I am sure he must have some opinion as to why this happens.
I can't find anyone here who knows, mainly because there are
not that many CDI vehicles here that are having this problem.
Here in N A, all MBZ diesels are V6s beginning with MY 2007 except for the
five cylinder vans which are basically your engine with one extra cylinder.
Most people here do not realize the many advantages of
driving a diesel like those of you over yonder.
Thanks for the update.

Costs Unveiled
Thought I might post the actual estimate that I finally received for all the works done. Just waiting for the Injector pipe to be delivered from Germany and be fitted. Hope to have my car back by the weekend

Will have a chat with the Thread Doctor and get his view on why this happen. Look out for an update after I have spoken to him.
Thanks for all you help and advice

Good Show Finally
Steven,
Good to hear. Nothing like a good running CDI.
What did the Thread Doctor say causes those problems with our CDIs?
What RPMs are you turning at 60 MPH when you're in your top gear (seventh)?
Trying to determine what rear end gears your CDI 220 has?

With regards RPM's at 60mph I am clocking about 1800 and just below 2000 when doing 80mph.

My Thoughts
Spoke to the 'Thread Doctor' today and he basically told me that from his perspective there had been a lot of taking the injectors in and out that led to the thread failure. Not sure about that part of the cars history
so going to try and do some investigation. He also pointed out to the wrong bolts being used!
That is why I thought it would be better for you to go ahead and have the 'Tread Doctor'
do cylinders three and four while he was there, even if that small extra amount
of labor would not be included in the warranty work.
Before the last time I had a problem, I paid only $15 USD at the dealer for parts
including tax for four stretch bolts and the proper copper washers to fix mine.
Labor for cleaning up the problem with cylinder number three and removing and
replacing the copper washers at the bottom of cylinders four, five and six was
only $120.
(A private mechanic, so no tax. It took him three hours and he came to my location.)
Better for you to pay a slight amount additional for it now out-of-pocket and know
that you would not have any troubles later than to have to go through later
what you've gone through now, isn't it?

Slightly below 2000 rpms at 80 mph, you were now in seventh gear for sure.
(2.65 X 0.73 or 1.9345 overall). Nice!
With my five speed, and slightly taller tires, I am running 2255 rpms at a true 80 mph.
Your sixth speed is the same ratio as my top gear (fifth speed).
Your seventh gear is a ten (10) percent overdrive over the
top gear of the older five speed transmissions.
