E46 330i to 330d Conversion

Hi, I am planning to strip down a 330d from England and send out all the parts in a crate to Ontario where I plan to convert my 02 330i to a 330d. I spent a summer in the UK driving a 330d and this is the car that made me fall in love with the e46. I love my car but I've always wanted the diesel which was not offerend here in Canada/North America. I wanted to know from an electrical standpoint, what I need to do in order to complete the swap.

From a mechanical standpoint I understand what I need to do to get it to work, but I lack the knowledge from an electrical point of view. I know that I will have to swap the dash, DME, and engine wiring harness. I also expect that a lot of coding will be necessary as well, but what else?

I believe this would be a first, and as we're a mainly NA forum there will not be a lot of resources to help much. I don't have anything to bring to the table other than wishing you good luck. Those diesels have tons of torque

Would not be too hard, just take everything from the diesel, form clock to fuel pumps. Fuel tanks from petrol to diesel are the same

subscribed....This would be a great thread

I would post your inquiry in the E46 Engine Swaps AND the Drive-line, Engine & DME Tuning subgroups as well.

I haven't done it, but have thought about it in other chassis (e39, e53)..I have done stock engine swaps and a manual swap.. I would think doing an EWS delete on the Diesel's DME would be a good place to start. Then in theory, you could use it along with the diesel's wiring harness (es?) and it might cooperate with the 330i's electronics. I am thinking you would have to code the car and several of it's modules with NCS expert..but that shouldn't be too tough...I am going to stop there as I don't know what I am talking about.

Please keep us posted..what a great project..

Last time I looked, you could import a 15+ year old car into Canada.

This.

It will likely end up cheaper just to ship the 330d over here. It will be a lot of work to first strip the 330d, then the 330i, then put all the stuff back in.

...unless he wants a LHD 330d. Still probably cheaper to just ship the whole car and swap everything over in Canada with both cars side-by-side rather than stripping it in the UK and sending the parts piecemeal...

Cool project!

Agree- this is a very cool- and huge- project, mostly from the logistics.

I too like the idea of shipping the whole car. You will find that the electrical system
will be very similar- right up to the point that it's completely different. And I for one
have no idea where that point will be!

The E30 is a case in point, You can swap engine harnesses all day, UNLESS there
was an airbag in the engine donor car. Then, a pin that was used for ground becomes 12v, unfused.
So an airbag car engine harness sets a non- airbag car on fire... unless you move pin 20.

Having the 2 side- by- side will make that a LOT easier to work through.

There will also be changes year by year, too. www.newtis.info will help with that a LOT!

Sounds like fun!

Cool project!
Or buy a LHD and ship.
