E90 330d EGR Disable

[Bossman]

I have disabled the egr on my car about a week ago, done a long trip, and found that the diesel consumption definitely went down. The car also does not smoke as much under hard acceleration, that shows that the combustion process is more efficient.
I read on Wiki and some other sites that this is true, the egr basically brings down the combustion temperature to stop the oxygen from combining with the nitrous oxide in the mixture, stopping excesive nox from forming.
I would rather see my car's engine perform better!!
I just disabled the vacuum to the actuator for now, causing the egr valve to stay closed, but will also replace the complete valve later on with a blank as I have done on my old 530d.
Also there were no errors logged with the mod!
I have the 2006 E90 330d Manual model (180kw, 520nm) motor.

I have the 2006 E90 330d Manual model (180kw, 520nm) motor.

Unless its chipped, the 2006 model is the 160kw/480nm version. LCI model are the numbers you've quoted. 2008 per-LCI had 170kw, but still the same motor as before.

Anyway, interesting read about the EGR :thumbs:

According to the vin number and engine number as well as owners manual, the figures I quoted are correct.

Sorry bud, but a 2006 330d is 160kw (or 170kw at the end of 2007/2008). Only the LCI came out with the 180kw motor - I think you've got your sources wrong.

Sorry dude, BMW even make mess up's, by VIN, by engine number, by everything, my car is a pre-faclift, by VIN, by engine number it is registered as an LCi.

bossman and msm I notice youre driving the same car but your fuel consumption is worlds apart why is that?

Big foot? :roflol:

 

[ntuthuko]

Bossman must have a huge foot coz his consumption is worse than your X5s

One is l/100km one is km/l... :fishwack:

Why have an EGR in the first place.


Now I wonder why is it that some quote that the pre lci 330d has 170kw / 500nm torque, others say 170kw /520nm and others also say 160kw/480nm torque.


how do we know which figures are correct (I am not being sarcastic or offensive. Just find it strange that different figures are quoted for the same model cars).

This is what I got from Wikipedia:
330d 2005–2008 231 PS (170 kW; 228 bhp) 500 Nm (369 lb·ft)
330d 2008+ 245 PS (180 kW; 242 bhp) 520 Nm (384 lb·ft)
335d 2009+ 269 PS (198 kW; 265 bhp) 576 Nm (425 lb·ft)
335d 2006+ 236 PS (210 kW; 282 bhp) 580 Nm (428 lb·ft)

To lower emissions so the greenies dont have a sh1t fit.

 

[XMAX]

so the EGR is not a necessary component. How can I delete it on my car...

When the E90 330d was introduced here, BMW SA limited it to 160kw/480nm, apparently due to our poor quality diesel. Then around the end of 2007/2008, they upped the power to the ones above (i.e. 170kw/500nm).

I assume that the bmw limitation was a detuned version of the 170kw engine or am i wrong and it was a hardware difference.

AFAIK, it was software only - no hardware changes.

@Msm - Good to know.

Cos this then means that the gains achieved by tuning to the 160kw and the 170kw version should yeild the same final results.

In theory, yes. I'd also be keen to know about this.

does anyone know what the 1st stage mod for the pre facelift 330d e90 is ? Ive heard a simple software upgrade from bmw can give you 13 kilowatts extra and 40nm ? please help guys im a bit new to the game.

Just bring the cars to us , we will sort it out.

330d is leathal if tuned correctly.

Sounding like a broken record now.

:sorry:

Geee I miss my Diesel!!!. Dont care what the dyno said after mine was done but it was fast! Broke a few engine mountings but it was still funnnn!
So 160Kw/170Kw or 180Kw, doesnt matter, after some hardware and software changes, the result is awesome.
