Thanks for toturial. I will try it Tomorrow Wish me luck :> Is it same for 520d ?

Hi. It depends which 20d engine you have:
- M47N2 or
- N47

With M47N2 it is pretty much the same. Good luck!

M47N2.

Thanks I just have one more ride Tomorrow and I will start my first operation with this car around 8am... Garage asked for £200... Blanking kit cost me around £32 (22mm)...

I guess for £200 I can do it...

BTW I guess it is good idea to clean up EGR ? Should I just use something special to clean it up ?? Or simple use some alcohol cleaning stuff from car shop ?

Anzafin

Nice.

Yes you should clean the EGR. You don't need anything special. A wooden knife or something similar will help to scrape off the stucked soot.

Job done, took around 3 hours to finish it. Most of time I spent on looking for lost gasket from bolt and I've lost also one bolt (from manifold inlet)... I found it and lucky me gasket ended just on middle of engine and bolt on bottom cover

Car is driving, no errors, hard to say if it is true or not but seems to accelerating a little bit better on 1st/2nd/3rd gear (1-2k RPMs)... Acceleration from 70-95 is also very good so I think that everything is working

And I had also problem with lots of air tubes under the whole manifold inlet...

Thanks for instruction guys Very helpful :>

Congrats! Nicely done!

Also a big thanks from me Antti, the DIY make the removal realy easy for me. I used these blacking plates : 33mm Swirl Flap Blanking Kits Including Seals . They are from plastic same material as the intake, cheaper but perfect for what they have to do.

My intake was missing one gasket from the last Bolt. But I wasn't 100% sure as it could have gone into the engine as I couldn't find it anywhere else.
This was the tricky part I found, when removing the intake it is possible that those bolt Gaskets drop of since they are arn't helt that firmly place, rubbing against the bolt that remains on the engine head is enough. Started the engine it ran fine, so I guess it didn't drop in. Its rather big and doesn't drop in that easy but it isn't impossible, so be carefull.

I also changed all the glow plugs as 5 of them where dead, also did the glow relay to be 100% sure. Took a torque wrench as I these glow plugs can break off, but they came out realy easy.

Worst job was cleaning the EGR.

Anzafin

Well done you too!
Thanks for sharing the tips about the gaskets.

Just one more question, not sure if that would be related.

Today during acceleration on motorway (68mpg -> 74mpg) suddenly car lost power, turned off cruise control, showed yellow engine icon on dashboard. Everything happened on cruise control (I just set 74 mph as target speed and second later it turned off with yellow engine icon).

No other problems at all during whole trip (around 150 miles, 140 miles on motorway)... Everything seems to be working, and icon were there just for 0.8 second maybe, if cruise control would go off I wouldn't be able to say that something happened... Any one had similar problem ? Is it one time problem or maybe just something with fuel ?

Anzafin

I don't know, maybe just a coincidence, but maybe you could recheck all the electric connections and vacuum tubing at first. Possibly there is a fault code restored as well. Reading that out would help to determine what caused it.
