Great news about the engine. You'll be cruising around before you know it!
If you don't already have one you really should get a MB Star/SDS/Xentry/DAS diagnostic tool (some other tools can do some things, but none can do all that this tool will do). As part of the software package there will be the MB parts catalog which makes looking up parts more successfully (MB makes part changes in production lines and the VIN is the dividing point not the model year) and WIS which is the MB service and repair manual.I have determined the 2 connectors by the driver's side dash should be going to the central gateway module. This forum has yet to fail me when I search an issue. Apparently I'm a liar and I did not take every electronic module from inside the 2010 because after looking through all of my loose parts twice I don't have this one. I'm going to look again, and get a little more organized in the process. I'm hoping I do have it because I also thought I had the drivers lower dash panel from the 2010 and I can't find that now either.
Just ordered a central module on ebay though, at 15.99 shipped I won't be upset if I misplaced it and actually do already have it. Hopefully it works and shuts that center console lock up in the process, and tells the car its not really moving so I can put the roof down. From what I have read it's like a hub of can bus communications among different systems so I'm guessing it's responsible for most of my electrical issues. It also explains why I have been unable to pull any codes from the car. Which is good news but for a different reason, it means my current diagnostic setup likely is working just fine, it just can't talk to the car without this module installed. I actually can hear that center console thing change sound when I try to pull codes the first time, so something is happening. I'll be leaving all of that alone until the module comes. It's been a good session of troubleshooting the car this afternoon and exactly how I wanted to spend my labor day. Now to wait for the mail to come.
So in the first new parts order I picked up a fuse box cover that goes under the hood on the driver's side. Guess what I found under the hood today hiding by the engine? A perfectly good fuse box cover. Need to be cautious with that. I hate returning things almost as much as I hate buying parts I dont really need. At least my fuses are covered up properly now. I'll put the new one on when it arrives, one less thing to clean. Stickers are flaking off the old one.
Biggest development of the day is a positive: Couldn't get the car to actually crank the engine until today. While I was looking over all three of the fuse boxes in the car I was sure to have a look at the ones labeled something along the lines of "engine start enable" on the diagram which apply to three fuses. Turns out I was missing a 15 amp fuse under the hood. I grabbed one and put it in, then wanted to bump the starter to see if that was all that was wrong. I wish I had recorded this moment to video. The moment I hit the key, the engine immediately started!! I didn't even hear a full revolution of the starter it was like I had just driven this car to lunch earlier and the engine was still warm. It scared me half to death and I immediately turned it back off, there is no radiator in the thing and I did not expect it to want to even turn over let alone fire up! So that's a big check off the list today. Engine is capable of starting. I may have ran it 3 full seconds while I took mental realization of what was happening and told myself to cut the key, but it sounded fine.
Since you have a much newer version of Xentry/DAS, the software you have may not necessarily include the whole suite of applications. In the past, everything was always loaded on the hard drive. The parts catalog is called EPC (Electronic Parts Catalog) and the service repair is called WIS (Workshop Information System). On my much older of Xentry/DAS I can access WIS from DAS but accessing EPC is more of a stand alone component. EPC is much improved over the typical online MB dealer parts catalog. It will show you an original part number and all the superceded versions. That is helpful in your seach for used parts. Or that you know the first couple early versions of a part had some issues so only look for the newer versions of the part. Also, MB is very good about knowing how every vehicle is built and the options it had. If you wanted to replace the left door speakers the parts catalong which version of speakers your car was bulit. Same as to a headlight assebly. The parts catalong will know which headlight your car was built (there are a couple of different versions).Thanks folks! I am familiar with LKQ, the 2010 parts car is in one of their yards. Still a useful tip though, as it reminded me it wouldn't hurt to call them and see if they can assist me in locating what I need. They have a lot of locations and they don't always put their best cars in the "u pull it" lots. I will do that this afternoon.
I am pretty certain I have xentry 6.20 working with a vas5054 adapter, but I will not be able to confirm it is fully operational until the new gateway module arrives. I also have another of those adapters coming, as I thought mine may be bad before I discovered the missing gateway module.
I'm being impatient and those modules are going for so cheap used I bought another one at 30 shipped with priority shipping. It's like a race to my mailbox, one is coming from florida the other california. This is also to help make sure I end up with a good and compatible part. One of the modules I bought came from a 2006 so I'm hoping it works out one way or another. I appreciate you taking the time to explain how the program works though, Mchild. It's going to be even better than I had hoped. I've yet to see it for myself, it errors out after trying to establish initial communication because I was trying to make it talk to a partial car. How does one access the parts catalog does that happen after the car is scanned initially? Right now I open xentry, select R171 and other options to ID the car then DAS opens to perform diagnostics and that's as far as I can go until I get my part in the mail.
