2006/2010 smart CDI in the US rebuild


Recommended Posts

Ok, sorry for going dark. That is all good information that I will definitely be reflecting on later. Don't forget Willies, the seller ripped me off and basically took everything except the trans, AC compressor, and alternator but I already had the built engine from a 54hp version. I have to buy and rebuild damn near everything. I believe the block and engine are the same throughout all models. It is just the addons, newer parts, and tunes that improve upon it. In a perfect world, the goal would be to build it to work like the 54hp version but have the looser emissions of the 450 (which the vehicle is and the standard I would be held to if anyone asks), as well as fewer things Canadian diesels require ( I believe). Also yeah, the brakes aren't a big deal but I despise changing drum brakes.

I noticed when looking at the engines over at MWSmart between the two models that there are differences in the castings where the water pump/alt/air con, etc etc are located.....I was simply searching for answers to my problem and noticed it.  That makes me believe that you can't simply make the later model work the same as the earlier model...?  That is by using the different year parts etc.  Then you get into the electronics of the whole thing. IMHO, it would be easier to simply buy a complete wiring harness from the same model as the engine is and work from there?  As I have said before, even taking a flight up to the Great White North and buying a wrecked car, taking the time to take everything off it yourself and shipping it back home as parts for your car in the south...?  I know not quite the legal way to do things maybe, but it may slow your white hairs from coming in prematurely...lol. After my ordeal and on going problems, it's what i would do. Izzy is the guy I would speak to and see if he can help? I know he has 450 CDI's but don't know if he has any 451 models . I'm sure if it was profitable for him he could find one...? Even I could but don't want the extra work involved in stripping it down. etc. IF you did the fly in and do the work I bet you could have it done in a weekend. Packaged up and shipped in the next day or so. Then the rest goes to the scrap metal man.  IMHO seriously the only way to do it and know you have everything you require.   Just my bent nickle's worth...sorry.

HMMMM, that's good to know. I actually did look into a 451 harness and that is doable. I have thought about it from the start actually. Even putting all this in a new clean gas body. With all the parts I am buying why the hell not. But what you are saying about essentially importing one is what I have now. I went the whole route trying it legally and had ALL the information, the agencies to clear it with, what I could and couldn't do but each agency wanted a signature from each other and no one would give me one. I also found out that if you remove the engine and trans it isn't legally a car and thus doesn't require any import rules. Then I found a Canadian who moved here with theirs, it died and here we are.

That is expensive. My 2009 cost me £500 in 2016 and my 2012 cost me £1000 in 2021.

I thought I had paid a lot for the 2012 but I needed it quickly as a motorbike had bitten my 2009. I just sold the 2012 for £1500 and have mended the 2009 which is a much better car.

CDI's up here in the great grey North are now very popular and are demanding a good dollar even if it is a Trudeau defunked dollar....lol.   Sorry couldn't resist...lol.

IF you want a good running car and that isn't a pretty one you can expect to pay $3500 and nice ones go far more!   Even used engines and parts cars aren't cheap any more.  I know of 3 parts car that have hail damaged roofs and he wants over $1,000 for them with mid km speedos.

I agree, simply swapping out all the electronics and power is an interesting way to go, BUT, the dash will be different which means you'll never get it to look nice, unless you can get the 450 dash to fit in the 451 frame ..?   The rest is simply hidden from sight, right?

 

I would go after a gas 450 if you have one and go that route. OR buy good used parts from up here and ship them in or drive up and fetch them back.  Your sub frame comes to mind as an example.  That stripped down even if separated between top and bottom parts can't be that much to ship on a truck...?   Like I sad before my neighbor drives down a few times a year and brings back stuff all the time so he could have space on the way down if he's paid for his troubles etc etc...?????

 

Then you have the issue with, never being able to sell illegally speaking...?   OR can that be done after the fact?   But I would simply run it till dead myself.

The few CDIs I saw for sale online some years ago are obviously gone but that price is a lot higher than it was. I'm surprised parts are that crazy. This one has a glass roof. Mine you this car is a 450 from 2006 NOT a 451. But really, I have almost every part from a 2010 451 CDI engine and its components.
Stripped down technically that should be more than enough, last I checked. The more parts the less of a problem. The only shipping example I have is shipping just a bare subframe from California to here is $700. I don't remember the cost of shipping the engine here from Germany.


I'll keep that friend in mind 100%! I am pretty reasonable when someone is willing to go out of their way to help me. Sadly right now I have $0. Really, at this point, I would like to be able to drive this thing. Roll the subframe under it and go. If that means just fixing the rocker I cut out and wheeling in a loaded subframe I would do it.
Regarding selling. I think that front is fine. I got all the titling, registration and insurance (briefly) done. The only tough thing is getting it here to begin with. So if I opted to sell it I should be fine. But after all this effort I would probably just keep it. I even started planning a trailer to haul it with.

I don't mean to keep raining on your parade so to speak, just going by the shit show I'm going through here with mine electrically speaking....and mine is simply same parts same year etc etc and still won't run right. So when mixing years and models, just the electrical now is a scarey situation imho. You imho need the entire electrical wiring harness from the 451 model to install into the 450 to get that 451 engine with it's sensors etc to operate as they want. That would be my thinking...? Maybe I'm over thinking it...??? I hope I am. I know how much you have tied up in your project as I too have gone way over board doing mine and all my parts came from MW-Smart. Not saying their prices are out to lunch in any way as they were the best I could find any where too, and at the time their shipping rates were excellent. Now I'm not so sure for the heavy bits...?  I have more stuff on it's way as we speak...lol.
I sure hope to see one day you get it running and driving.

No need to worry. This is all good information to have. Honestly at this point, if I could get one over here it would probably still be cheaper than finishing the one I started. Even the body, suspension, abs sensor, so much is rusty and broken. The first thing I can do is just get it put together and just see what happens. See what sensors aren't happy, if it will start, etc.. I am stuck waiting though. The Mercedes dealership is still waiting on 70 parts of about $1700 in parts I ordered over two months ago. As for MWsmart, I believe I am the last or one of the few Americans they are still selling parts to. That's what they have told me anyway. I made a big purchase and have actually sent payments after ordering the parts. Other than the VAT tax it's pretty good on shipping. They will even sell me a subframe. The engine only had a couple hundred in shipping, if that. Well, the engine was $1850 and shipping was $39 lol. Something like that.

These days it just seems to be a whole lot of waiting. That and money lol. And random events like the garage flooding.

Great news! I just received my 75-item order for most of the fittings. It took 8 months but I got it. Unfortunately, I still have a class and work started up again so I cannot devote full time to it. I can tinker and build the engine in the living room while I weld up the body in the garage. I finally figured out how to weld the stainless sheet metal I am repairing the rockers and body with. While I am at it I should probably make a little door over the hole the guy cut to get the starter out.

I have the same hole in mine when the previous owner changed the starter that way.  I am not getting any fumes inside the cab so I think he did a pretty good job at sealing it.

I don't understand why you would do it. It is not that hard to drop the subframe, certainly easier than cutting a hole. In my opinion the car is scrap once that hole is cut as it weakens the tridion and is not designed to be there.

This all depends upon your skill levels, far easier to carve out a hole than do it properly, imho...lol.  Once you drop the sub frame the first time, you'll never work on the car again without dropping it. It makes things so much easier to work on.

Sorry for the delay. I was having trouble logging in. The guy probably cut the hole betting on my ignorance and the cost of the purchase. I am not sure that the sheet metal of the body panel counts as the tridion. If you weld and or reinforce the hold as opposed to bondo, structurally it's fine. Actually welding even passes inspection for structural areas. The whole thing does give me flashbacks to people cutting holes in their SUVs or truck floors and adding a door to get to the fuel pump because a mechanic charges $600 at least to do that. An access port would be nice though but a big enough one to really be useful wouldn't work. I did replace an alternator once and that SUCKED.

I have decided I will have to scan the entire German book to rebuild this. Unless someone has a link or some full engine tear down or rebuild. I just need to see where the pieces go. The Mercedes software is helpful but not very descriptive. Can anyone list the individual emission components of the 06 CDI and maybe the 451 54hp version? It would be nice if I could replace the original broken emission components with ones for the same model. Of course to keep with the original 2006 CDI. Which I have heard was a lot more reliable and got better mileage...

Really I just need to find a engine build video.

Sadly there isn't any technical schematics/diagrams worth anything to go by. Yes I have found some electrical schematics but not a complete set. The mechanics are easy so to speak, it'll be the electrical issues that will stop you dead in your tracks I'm afraid. These car are so fussy with the exact voltage or resistance values to anything that the slightest bit off and it'll never run right. Ask me how I know...lol.
You have found my engine rebuild pics, this is exactly why I posted them. For anyone who didn't know where things were by reaching into the abiss trying to figure out what their fingers were touching...lol. Also the internal parts if you have never rebuilt an engine before.  You still must know clearances etc as in any engine rebuild. 
Good luck and if I can help simply ask.

I can tell you about 54 electrics / wiring but I aint about to write a book about it. :)

Ask I and shall attempt to answer.

 

If you need anything specific in the way of pictures I have a 2009 54 and a spare engine in the shed.

 

Cannot help with the 451 45 or the 450 CDI, they didn't really make it to the UK.

Oh, my god @Willys that was you! HAHAHA, I didn't even put two and two together. I just saw that a person had exactly what I needed and commented. I will tell you both that I do not even care about the wires at this point. I just want it together and to get my kitchen back haha. And yeah that blind reach into the abyss is a rough one for sure lol. I am still short about 25 small parts that I will likely have a friend in Europe purchase for me. So with the two of you, it looks like I have an owner of each vehicle which is great.

 

I did contact Evilution just because why not so I have that in my back pocket. I didn't know that the 06 450 CDI didn't make it to the UK until he told me. So I guess Canada and Germany? He didn't have much experience with either actually but he could probably help with the LS swap. 

He pointed out that the 54hp was ruined both for reliability and performance with all the emission parts. And that the 450 had little to none of those parts. I have purchased some of those 54hp emission parts so I wanted to know what specifically they were so I could just not install them and keep to the original spec. Once I get this all put together then I can really worry about getting the body all fixed up.

 

@Willys should I just PM you for all the really small nitty gritty questions or keep it here?

 

This is all such good news and I am so excited!

Feel free to PM me and IF I am not glued to the TV, I'll do my best...lol.
I wouldn't install any of the emissions onto the engine that the 450 didn't come with. I'd get yourself a set of computers from a 450 and start working with that as a target. IF you don't have a set I may have a spare set, which I could program to speak to each other, maybe? No promises seeing as it also depends upon what wiring harness you are using. After the BS I'm going through with my electrical I'd be very careful about trying to miss match the wiring to the computers.....and sensors.

Fantastic! Thank you so much. The physical engine is from a 54hp model. All the electronics and computers are from the 450 and are still intact. The only thing that might give me slight pause right now is the injectors and the high-pressure pump that screw to the side of the head to the cam. The sensors I have are all 54hp models but they just gather the readings they don't do any smart stuff I think. If need be I will buy new ones though.
