apart from the increased hp and torque what the main differences between the 3.0 engine fitted in the E92 LCI 335D and that fitted to the 435D ...... does the later engine still have the same characteristics of carbon build up in the EGR value and intake manifold ...... does the 435D engine have swirl flaps?

would be grateful for any information that can be provided

[rasa bmw]

yes,and the e series had the m57 engine and the 435 the newer n57 alloy block,,and yes it has swirls,,but not seen any that fail,egr cooler yes,i sol;d my e92 335d and have the 640d engine same as 435d,althiugh the ecu is mounted at front left compared to top right on the 435d

The M57 fitted to the E90's is alloy too, mines a 2009 and is definitely an alloy block.

not on the 335d .even if its an 2011 car its an m57.lci e90 330d/325d is n57 not m57 and is indeed alloy block

Hi Rasa, mines a 2009 LCI and has the M57n2 which is an alloy block. Mine is not the N57, it still has the shitty long tubular air filter that's a pain in the arse to change and the long fingered (old style) manifold. The first year of LCI 325d's had the M57 engine for some reason. One reason I chose mine was BMW didn't fit swirl flaps in the 325d variant so that was one less potential headache to worry about.

Didn't realise the 335d's had the older steel block still.

M57D30TÜ2TOP (2006 onwards) is using aluminium block as per wiki.

pretty sure some n2 had the cast block,had to do with parts that lay around,,they do not throw them away...will try and find where i read it

[Silver Streek]

The TU2 (n2) engines as fitted to Ex series are supposed to be ali blocks, but you are right rasa I can imagine if they had cast iron blocks to use up some will have found their way into Ex cars.

[Bluewater335D]

so does the newer 435D engine suffer carbon built up etc., similar to the earlier engine

there seems to be more problems with the EGR on the later engine - I have read about BMW recalls in this regard

[ValSolo]

N57 tends to suffer from carbon build up even more than M57. Walnut blasting once in 100k miles would do just fine.

As for cast iron vs aluminium, you guys don`t even need to leave the forum:

one of the reasons i get egr deleted via software,stops operation and build up,and it totally depends on how the car is driven and been driven,drive them as intended and carbon build up is minimal,drive them to the shops and back all the time and it will build up quicker..

"BMW is extending its recall of diesel cars, after it was found that faulty parts could lead to a potential fire risk. In 2018, BMW originally recalled 268,000 UK diesel cars after it was found that glycol leakage from the engine’s exhaust gas recirculation (EGR) cooler could result in burning soot deposits when combined with the high temperatures inside the EGR system. Now, this recall has been extended to a further 27,000 vehicles in the UK"

mine had a new egr cooler in 2015,,then again on 17th march 2020,,first one was a like for like,2nd time was revised/new part,2012 640d
