You can see for yourself what the differences are.
When the LCI 525d came out there was a lot of speculation that the difference between it and the 530d was just software. This is not so.
The 2993cc engines are NOT the same but many items are.
The turbo IS the same, so too are the camshafts.
The 530d has larger intake valves (27.4mm Vs 25.9mm) and has a vacuum controlled intake manifold.
Kills that myth...

Good find - you may recall this is something I've always been interested to know for sure. Didn't realise RealOEM had been updated - I will take a look - Cheers!
Not the answer we were looking for perhaps, but it does confirm what I read on a 3 Series forum recently.
The auto box is different as well rated at 400Nm rather than the 600Nm of the one fitted to the 530d (and 535d). It is actually the same one as fitted to the 535i which has the same stock torque (400Nm = 295ftlbs).

Yes, I stumbled on the update by chance.

I've just been reading about you SAT Retrofit - sounds great. Pity I went with the manual gearbox. Part of me really wishes I went for the auto, while the other part really loves the manual. May go for Auto next time!
Noticed that you say the Auto Gearbox is also different between the 525d & 530d. The Manual Gearbox is however the same on the two.

Hartge offers a monster power increase from 197 to 270ish for example. No doubt the NM value also goes from 400 to well above 500nm. Sounds pretty risky to me
Any thoughts??

So does that mean anyone remapping the 525d will seriously be putting their auto transmission at risk??

Wonder what the manual gearbox is rated to?

I know that the E39 530dA had a auto transmission, which was limited to 390NM. Some owners who did a remapping, really got in trouble later on, since the auto transmission couldn't deal with the high torque.
The X5 (E53) 3.0dA had the same problem.

Nor 530d vs. 535d.
But there are only two 3.0 l aluminum engine blocks for the new E60/61/63/64's.
Gasoline (525i, 528i, x30i and x35i) and diesel (525d, x30d and x35d).
The new x30d F01 and E90/91 diesel engine block is brand new.
All these engines have different engine tops, electronics and turbos etc.

The auto box in the 520d, 525d and 535i are all rated at 400Nm. The 525d and 535i engines are both rated at 400Nm as standard. The auto box in the 530d and 535d is rated at 600Nm and the 535d is rated at 580Nm as standard. The 520d engine is rated at 350Nm.
Remaps of 525d and 535i add about 80-120Nm whilst a remap of the 535d will add about 70-100Nm.
Thus where you rempa, the 525d and 535i gearbox rating is being exceeded by more than that of the remapped 535d. However from what I have read, it is the form of the delivery which can do more damage than the out right numbers.
Hartge don't list the 271hp/591Nm option on their website any more but ESS still list one for 280hp/600Nm but with the caveat that this is only for a manual box. Their phase 1 remap is marketted as 550Nm.
Elsewhere, I have read that the gearbox has a 20% safety factor. Frankly it must have some factor as BMW wouldn't put a 400Nm gearbox on a car rated at 400Nm! My hunch is that you wouldn't want to go much higher than 500Nm on the 525d. In real terms, this is probably the limit of a sensible remap anyway.
Based on this, the 520d and 530d are the ones with the most safety factor in their drive trains.
I for one would have been happier remapping if the 525d had the stronger 'box, but there it doesn't always work out that way!
Regards,
David.

Intake manifold- LCI 525d - http://www.realoem.com/bmw/showparts.do?mo...hg=11&fg=40 - E60N 525d INTAKE MANIFOLD- WITHOUT FLAP CONTROL
Intake Manifold pre LCI 530d - http://www.realoem.com/bmw/showparts.do?mo...hg=11&fg=40 - E60 530d INTAKE MANIFOLD- VACUUM-CONTROLLED - part is: 01 INTAKE MANIFOLD WITH FLAP CONTROL
Spot the difference in the naming conventions...
Does this mean no swirl flaps????? Or am I hoping...??? Or is it to do with the Vacuum hose and connectors? Anyone know? Has anyone dared to take the inlet manifold apart to check on the LCI's - especially the 525d????
Here is the E39
