Deleting EGR on my Mercedes E420 CDI

[@mihaillujanschi5193]

Its cool to see that after all those years you still keep your w211 with you :)

[@petermuurman7624]

Wonderful. Did exactly the same and in the same way on my e420cdi. Combined with cylinder head gaskets and total clean up and rebuild of heads. Wonderful engine. Got the car now for 1.5 years and done 75000 kilometers with it and was inspired buying one by your video's! Got a mild tune and cat and dpf still in. 830nm and 350 HP. Plenty for me for now. And better for Dutch MOT regulations. My Daily driver so drive 1000 km each week and needs to be legal here.. I absolutely love the color of your car. Great job once again 👍

[@bkorven]

Nice! What a great feeling having all that done. I wonder in what shape my cylinder heads and gaskets are in. Inevitably, the gaskets will need replacing in likely not too long. So cool to hear I inspired you to buy one! 350 hp sure is plenty. Thanks alot for your comment!

When removing the pipe that goes from the intercooler to the intake manifold, did you have to loosen the intercooler or the manifold? im trying to replace the accelerator valve on my e420cdi but cant get the pipe to come off. @3:10

[@bkorven]

I loosened the intercooler, and let the manifold be. Yes, note that the pipe sits firmly to the manifold! I also had to deal with that. You'll want the manifold in place to hold back while you pull and jerk! Use penetrating oil and be persistent, haha!

[@elgrandosmokio995]

Hello, you are doing a good job. Can you tell me whether the OM629 biturbo diesel is reliable? Should I continue with the OM642 diesel or should I continue with an engine prone to problems with regular maintenance, quality workmanship and original parts? Which one do you recommend? Fuel consumption is not important.

[@bkorven]

Thanks! In my experience, it is reliable. My W211 (this ML belongs to a friend of mine) has 230k km on the odometer, and I've basically just done regular maintenance. It's been with my family since new, so I have all the history on it. The EGR-system clogged up the intake quite badly with time, so that has been cleaned thoroughly once as preventative measure. The glow-plug module has failed (common problem with OM629.) And the engine mounts needs replacing more often than on the average car. Other than that, the engine has been very reliable. Some parts are quite expensive and hard to find, due to the rarity of the engine. But the common maintenance parts are readily available. It's hard to recommend one over the other without knowing your preferences. OM629 is something very different from OM642. If you want something special, more powerful, and do not care about some parts being hard to find, I'd recommend OM629. If you want an engine easier to work on, and easier to find parts for, and a very reliable engine, I'd recommend OM648 over both OM629 and OM642. But I don't think you should care too much about reliability, since as far as I know they can all be reliable. OM629 is just a pain to work on, sometimes. But it's such a lovely V8 when it's running, and I would never trade it for any of the other options.

[@Puzkajuzzi]

Great video on the coolest W211 ever! How many kilometers have this car done? I am asking because I did EGR delete on my OM629 at 90k km, wondering if mine would look as disgusting 😅 Also interested why you decided not to do EGR delete at the same time when you deleted DPF and you did ECU tune. Increasing fueling + having EGR active = not good 🤔 There aren't much videos here related to OM629, like others have already requested, you need to more of these!😄

[@bkorven]

I realized I had missed your comment. Sorry about the late reply. Thanks alot! This car has covered roughly 210 000km. Although there are some things that can affect the rate of build-up, I'm sure yours won't be quite this bad! 🙂 About not doing the EGR delete earlier.. I sure should have. At the time, I didn't have in mind how badly it would affect the intake in the long run. About the extra fueling; the ECU was also programmed to handle the extra fuel with a reasonable amount of extra air. Hard to say if this has had an impact, but the intake becoming like this is inevitable with EGR. I will definitely make more videos in the future. Again, thanks!

Hey, how is the fuel consumption and the reliability on this car?

[@volttilehtimaki2289]

Did you replace any gaskets when removing and cleaning the manifold? I was about to change the accelerator valve and saw my manifold was way dirtier than yours (335tkm). And when doing the egr delete do you think its enough to just jam the valves shut after having the egr coded away?

[@bkorven]

Yeah, I replaced these gaskets: - A 629 098 09 80 - A 027 997 34 48 (x2) - A 029 997 54 48 (x2) - A 016 997 52 45 - A 027 997 16 48 - A 642 188 05 80 - A 629 142 08 80 I can imagine that yours were even dirtier, at that milage. No one is spared from this, unfortunately. You actually do not need the block-off plates at all, I think. You don't need to bother with trying to somehow physically jam the valves, either. The valve position can via software be adjusted manually to be fixed shut, and then with EGR-off there will be no codes.

[@oskytrosky]

amazying, what about software? any error codes?

[@bkorven]

Thanks! I'm getting P0401, related to insufficient EGR flow. As expected, ofcourse! It's getting completely new software including EGR off next week.

[@TIME-LAPSE-MODE]

[@amtrack5348]

Did you receive any error codes with that hardware-EGR-delete? The main (and electronicly overwatched via OBD) part is still in place and I wonder if the car notices the missing EGR flow in the intake somehow. Also how did you block the other side (the round pipe)? Thank you very much in advance from a very interested GL420CDI owner 😁

[@bkorven]

Yes, I received the fault code P0401, related to insufficient EGR flow. So the car notices! The other side, as in the single pipe with the expanded end? That goes into the intake pipe before the manifold? That is the cooler for the exhaust gases from the EGR. Does not need to be blocked, since no exhaust gases enters from the other side. Or were you referring to something else? Nice to see a fellow 420 CDI-owner commenting!

[@bkorven]

Hi! The software, with EGR off, is custom made by a local tuner.

[@streetracer9412]

Wow lovely work 👏 And the sound is just awesome 😍 I have a tuned 535d and I recently got a GL420 love it so far, great machine. I have one issue though and I was hoping for an advice because these engines are not very common, atleast in my country. (DPF deleted) The car starts smoking white/gray when it is being idling for a while (20 mins), stops when I take off... and if I drive it on the highway for a 100km the COOLANT starts going out of the cap 🤯 Then error for adding coolant pops on the dash... but if I drive it around the city - no issues.. Can you advice what could it be? I am really hoping it's something small like the EGR cooler, not headgaskets or worst?

[@bkorven]

Thank you! All right, nice! To decide whether it's failing head gasket or EGR cooler can be a bit tricky I guess, since some of the symptoms would be similar. Unfortunately, failing head gaskets is something I've heard alot of with these engines. I can't remember having heard of the EGR cooler leaking internally. Although, leaking EGR could explain the exhaust smoke at idle but not while driving (valve opening being proportional to load, fully open at idle and thus a higher amount of coolant in the exhaust). However a leaking head gasket could probably do the same. If I have to guess - head gasket, I'm afraid. However, if it's the head gasket there is a high possibility of the engine oil and coolant mixing, so check the oil for sludge (under oil filler cap, for example).

[@streetracer9412]

​@bkorven Thanks for the advice, it was the head gasket cracked, the right one. There were signs of an old repair and they have changed only the right one with some crappie brand. I have changed both and serviced the engine. I am so happy with it. The dpfs are deleted and it has a remap. Very quick for a 2.5ton truck 😅 I have one issue though it smokes a bit when its pressed hard and even more if it was staying at idle for some time. I am guessing the Egr valves are getting stuck..

​​@@valilucy9281 Sorry about my late response. Is it the CDI? If so, I'd first of all suggest to go with straight pipes, eliminating/deleting whatever exhaust components (one at the time, if you'd like to test the sound in steps) there are that reduces sound level and flow. In other words, save money and don't bother with any after-market mufflers. If it's the petrol you should be more careful with the exhaust to make it sound nice. I'd personally start with a resonator delete, replacing it with an x-pipe. Having quad tips or stock is just a matter of preference. I love the stock tips that come with the Sport Package, and would myself at this time probably keep them. Again; preference 😁

Hey such a lovely car! Are you gonna give it a stage 3 upgrade and how is it doing with stage 2 now? And did u have races against 535/335 with ecu tunes?

[@bkorven]

Hi! Thank you! I might give it a stage 3 upgrade someday, but it's not something I have more closely planned. It's been doing super well with stage 2 for the past 10 years, but since EGR-delete I've begun to experience problems with turbo boost turning off completely. I believe some of the soot and muck from the intake valves found its way to the turbos, and are making the variable vanes in the turbo stick. This could result in too slow responses in turbo pressure, and then safe mode with no boost at all. So that's something I'm looking into right now, we'll see what it turns out to be. Back in the days I raced an E60 535D with exhaust and tune. It was quicker than my e420 cdi at the time (which only had a piggyback chiptune).

I use oil with viscosity index 5w-30. Any of 0w-30, 5w-30, 0w-40, 5w-40 could work fine, and you probably do not need to worry too much about it. There are some benefits and drawbacks with each viscosity index. If you've got both DPF delete and EGR delete I'd recommed using quality ACEA A3/B4 (ACEA C3 for a stock one). Any brand is OK, and you may as well buy the cheapest you can find. Rather be careful not neglecting oil change intervals.

[@bkorven]

Thank you! If you wish to achieve an interesting exhaust note, I'd advice on deleting the cat as well. Also, make sure not to just hollow out any exhaust component, as it will have a bad impact on flow and sound compared to actual straight piping. The impact on exhaust note by EGR delete is in my experience small (or negligible, even). Also, keep in mind that my car has a V8 while yours has an I6. An '04 320 CDI can sound fantastic nonetheless, but just different from what a 420 CDI sounds like. If you run straight pipe exhaust all the way from the turbo, I'm pretty sure you'd be happy with the exhaust sound!

Why doesn't black smoke come out if you delete EGR, also isn't it good for fuel consumption

[@bkorven]

The EGR-system for diesel engines is intended to lower NOx-emissions, and not particulate matters (black smoke). I don't think there's any difference now from before. I don't think the EGR-system has any significant impact on fuel consumption. I can find arguments both for and against, which might require a little closer analysis.

[@Shockload]

@@bkorven Okay what are the benefits of deleting it ?

[@bkorven]

@@Shockload The main reason for me to delete it was as a preventative measure, to avoid build up of the thick sludge deposits inside the intake. It was pretty bad, and in the long run, that will reduce performance. Having thoroughly cleaned the intake now, it's nice knowing it will stay clean.

I have a Mercedes GL 450 cdi in stage 1 (370hp-915nm) I would like to have 400hp what modifications are necessary?

[@bkorven]

A simple way of gaining a boost in power is to straight pipe the exhaust system. DPF delete will make the biggest difference, and with optimized ECU-software you should be able to make 400hp.

Maybe you know how your tuner got around EBP problem?

[@bkorven]

@@stnjkbs6062 As in exhaust back pressure? What problem would there be about it, do you mean?

[@stnjkbs6062]

Exhaust back pressure sensors yes. Got ecu tuned egr and dpf off but getting faults as EBP values plausible when accelerating. Did egr delete the same way as in video and i think ecu doesn’t see changes under acceleration on ebp values so it goes limp

[@bkorven]

@@stnjkbs6062 I realized you're probably talking about the pressure sensors upstreams the EGR-valves. The tuner I went to did not solve it. Although, my friends ML420 CDI is running successfully with these blocking plates. So either there's a difference in the EGR-system between the ML and the E, or the tuner of the ML managed to do something my tuner did not. I'll investigate it when I have the time, but my last option will be to restore the exhaust pipes to the valves and then close the valves via software.

[@stnjkbs6062]

@ yep, i was thinking the same, my tuner tried multiple times, even disabling sensors but problem occurred the same without fault codes. Probably restoring exhaust flow to egr in a few days or relocating sensor

[@bkorven]

@@stnjkbs6062 That is correct. The problem seems to be connected to the pressure sensors, but to me it does not make sense. What function does these sensors have, except the monitoring of the valves themselves? Why couldn't the pressure signal be ignored?

Hey! I used google translate for your comment, so I hope I got it right. I have deleted DPF and rear mufflers, and not just the mufflers. Also, the sound is slightly louder in this clip since the variable vanes of the turbochargers are fully open. Blocking the EGR is a multi-step procedure, and difficult to fully describe in a comment. However, the EGR can be setup to be shut via software too! Thank you very much for your comment!

Use E85 in diesel. It will clean the engine, it does NOT harm the engine in any way. I tryed this my self. Say you have 20 gallon diesel and a quarter of E85. Its verry littel you use....but this whole never be a problem. Once a month is Moore than enough.

Hello guys, next week I will buy a 400cdi with the om628 in it. My main question is does anybody know where I can find a good exhaust system? Want also to have a deep V8 sound like this 420😅… another question I have is, is there any forum for crazy diesel guys like us haha? because Im not planing to let it stock😂 and want to lern about the car itself.

[@bkorven]

Hey! I'd say that you should be prepared for not being able to find any ready-made exhaust system for your car, since it's so rare. But having a custom-made exhaust system (preferably straight pipes 😉) made for you should not be any problems. There are definitely several forums for diesel guys in general, that I bet are great! Otherwise, I've started a facebook-group for owners of cars with OM628 & OM629. Among other things, we help eachother out with project plans and the like. You are welcome to join, if you'd like! Thanks for your comment!

[@lukakrejic5081]

Thank you so much for your response, Im looking forward to make a clean build because it only has 100.000km and these cars, in good condition, getting more expensive at the market at the time. I would love to buy a straight pipe exhaust and the fact that it has no dpf is great, even if its not legal in austria but who cares haha. Im sure Kleemann do a good job, can u tell me how much u paid for the custom made exhaust? Sure Im joining the forum on Facebook and Im thankfull that there are guys like u wich are responding.
