335d cracked egr cooler delete/replacement
Does anyone know if egr delete kits are available to remove the complete system including the egr cooler? (Car has been remapped with dpf delete)
Or am I better of just replacing the cooler. Done a search on the forum and found a chap who has made a kit over in the states. Something similar on this side of the pond would be ideal. Thanks Harmeet |

Theres a write up on one of the forums, might be on here, i cant remember.
You need the EGR delete pipe for the throttle body part, you need two 18mm pipe caps to blank off the coolant feed/return, and you need a blanking plate for the exhaust manifold, which i believe is on ebay: http://www.ebay.co.uk/itm/53-8-mm-EG...item2a31511cc9 Once you've got that lot, you can completely remove the EGR cooler. I would definately remove it all, you dont want all that manky exhaust gas clarting up the inlet manifold, it makes quite a mess in there. |

The first thing you need to consider, is if you still have the DPF, and you remove or disable the EGR, its likely the DPF will stop regenerating and will become blocked due to the resulting EGR fault.
I'm unsure if the EGR can simply be coded out to fix the regenerations, or if you will need to remove the DPF as well. You'd need to speak to a tuner about that aspect. If your DPF is already deleted like the original poster then i'd imagine you can just remove it and even if it does create a fault code, it wont cause any issues. The hardware you need is a EGR replacement pipe for the intake manifold. Usually thats all people do but if you want to go the whole hog and delete the cooler as well then you also need a blank for the exhaust manifold, and two blanks for the cooling pipework. |

Thanks for that Aragorn30d
Also managed to get the cooling system pressure tested and found that the egr stat was leaking so no cracked egr cooler, but will still be doing a delete. Quote:

sorry to hijack the thread.
I was asking an independent garage about removing egr, I was advised against it. I was told it wouldn't run right, would need a fuel tanker following me, put strain on the fuel pump amongst other things. I have removed egr on other cars with no detriment at all. What I would like to know is how detrimental is removing the egr on these cars? Could the technician have been erring on the side of caution or was he genuinely right, after all he sees these cars most days. If I was to remove it I would do the necessary other eliminations of components to make the car run with no faults. thanks in advance. |

If you still have the dpf on the car then you cant's simply remove it as it will have an impact on the dpf regeneration process.

EGR Valve & Cooler Removal
Appreciate this response is probably a bit late for most people who have already posted here but may help anyone who is looking for a solution to the EGR issues that these cars invariably seem to have.
EGR Cooler & EGR Valve removal kits can be found here http://www.fixmyvw.com/egr-race-pipe...5d-and-x5-35d/ If you use one of these kits you will require the ECU to be reprogrammed (it can be done) In Europe try http://mega-speed.de/ In North America try JR AutoTuning in Canada http://chiptuning.ca/ at the time of writing they sell the AARodriguez kit for ~CAD290. At the same time you can get a Stage 2 Tune and turn your 'd' into a rocketship. The DEF will still regenerate but you will need to monitor the differential pressure. As the main cause of all the woes on the BMW M57 engine cars originates from recycling exhaust gas back into the intake another thing that will help is installing a catch can to prevent crankcase oil being fed into the intake manifold https://www.ecstuning.com/b-ecs-part...779ecs05a02~a/ |

any removal of egr and or dpf needs remapping out ...ive seen some many remapped cars that have had this done and they have problems ..theres a lot of people out there who think they can but cant !!!
regards the egr that works in conjunction with the maf sensor and just think it as a balancing act with air flow and exhaust flow |

Sorry for reviving this thread but just wanted some advice. I have a late 2008 E90 335d with the M57D30 engine.
I want to do an EGR delete. Please can someone clarify if i need to plug the pipes going into and out of the EGR cooler itself. I will be putting in a plate like the one shown in the link below at the exhaust manifold side but after speaking to a local tuner, he said i need to leave the EGR cooler as it is otherwise, plugging it will cause problems. https://www.ebay.co.uk/itm/Bmw-EGR-a...53.m1438.l2649 Thank you very much in advance. |
