LOL, nice idea, but most of my MB Customers are waaaaay too tight fisted to put fuel in a Supercharged Petrol Engine ........................
I'd say 85% of the Cars I work on up here are CDI 's
I don't really think it's that tall an order, I'm sure someone in a 32 will likely drive up near me or some guys have probably got a spare, it's just a matter of finding the correct person, who is trusting enough to know that I'm not going to sod up his Car / spare unit !!
Like I said, if someone is coming past mine it doesn't even need removing from the Car, and takes longer to boot the SDS up than actually copy the Coding.
There is another possible option, but involves taking my Car 120 miles round trip to our Main Dealer, then plugging in a V8 TCU, and getting the Dealer to Version Code it for a few beer tokens
For some reason, (saying this I've only had to do one), but I could only do this on my own SDS by copying first, then plug in spare Module and transfer the Coding ................
It gave me a nervous moment, as I had binned the faulty TCU, but luckily the bin men hadn't emptied it !!
They aren't like most modules where you can just code different options lines from a list until they are correct, I believe if a TCU is so FUBAR it won't read, or if you want to do a non standard coding like I do, then you have to get the Coding from MB Server and flash it to the new Module ....................
Fact is that may not work in this case, because MB Dealer's software is so "idiot proof" it may not allow it as my VIN will likely only allow the 3.27 V6 Diff plus V6 Trans Ratios Coding !!
Lately I have been unable to contact that other guy who said he can custom code these EGS 52's, but right now I'm just looking at all my available options, and as I have a few spare EGS-52 TCU's it makes sense to have one ready coded for 3.07 Diff
When I get some spare time I'll have a fiddle on one of my own Cars and see if there is something I missed before, way back years ago when I did my own W220 TCU
