This thread confuses the hell out of me.....I just can't wrap my head around the idea of voiding the hell out of your warranty, spending thousands on a retrofit, having to replace all of your fuel lines, pumps, transmission, drive-train parts, etc.. just so you can buy diesel which only costs 10c less than premium?

The whole idea of swapping the petrol for diesel engine is insane . On top of the million other reasons quoted in this thread I imagine the car would no longer have 50/50 weight distribution due to the sheer mass of the diesel engine

because you have more power at lower revs - and on a day-to-day basis in regular driving, this is where you need it. Huge overtaking power with minimal effort.

Not all of us have access to race tracks to redline their cars with impunity, and most normal people dont race on public roads either.

I hate having to rev the living daylights out of a car just to get her to move.

If you're trying to overtake an F1 car, maybe, but for most of the cars in my area, my 535 in sport mode gives me no trouble.

People keep mentioning this torque thing. Where does this torque thing prove to be useful? 0-60 the petrol version is faster. I don't do any highway driving so 65 or so s about as high as I get on a daily basis. So of the power comes from 60-100, I guess I have use for it. Plus, it's not like a tune like a JB3 couldn't fix the rolling start speed. Sorry, but I'm not sold on diesel power when it comes to cars like ours.

+1 personally i think it is a very bad idea, and i do not see the point at all, why didnt you just buy a 3.0L tt diesel in the first place instead of wasting the time and money to convert something that would not even save you enough money to make the swap even remotley worth it...and the 535 engine is a sheer pleasure to drive...i say stick with the 535 engine.

I guess it depends on where and how you drive, and your economics.

Where I live, you don't really get to 60, let alone 30, very often, so the 0-60 speed is irrelevant. My real "driving" comes on my early morning commute (motorway + some twisties), where I'm more interested in my 50-75-55-90-50-80-45-90 (you get my drift), which my 530d does a heck of a lot better at than a 530i (I've done the drive in both) due to its torque. Then there's the 80mph motorway cruise which my 530d does at 1,800rpm or so, taking me close to 600 miles between fillups. So, until the day comes when I am comfortable spending the $180k or so local list price for an M5, and filling it up at $7 a gallon, the 530/535d is just the ticket.

Hi all,

Sorry I've been on vacation, and couldn't reply to this post.

First of all, 200,000km for me is 4yrs of driving (I drive a lot)
Second, at 80,000km the warranty is toast anyways, and I am not sure if another "extended warranty" company will honour their warranty because I have the Dinan tune.
The car I have (535xi) is only available in 3.0L TT gasoline engine in North America, so the option of purchasing the diesel version was out of the question
My car burns 13.4L/100km of gasoline, the diesel will be 8.0L/100km at most. The savings of gasoline vs diesel in fuel costs alone are $10,800CDN given the assumption that a little of gasoline is $1.00 and the diesel is the same. This alone is an incentive to switch.

My original post stated "I'm just throwing this out there", I wanted to get some feedback, and understand the complications involved with a swap. There is a good chance that I will start to like some other car and buy it when the lease is up on mine. But I wanted to know if it is "theoretically" possible.

Anyways, thanks for the replies.
