F30 N57 EGR delete kit recommendations?
After having problems with my EGR it’s getting deleted and tuned out. Can anyone recommend a good delete kit??
Also Gona remove the inlet and give it a good clean, so if anyone has any tips on making it easier.. let me know! |

If you’re going to physically blank the EGR you must also have it coded out, not just the open/closed operation of the EGR valve but also reprogramming of the ECU regarding various expected values.

Have a chat with Darkside Developments, they know a thing or two about egr deletes.

Yeah exactly that, I’ve had a stage 1 put on my car and he said he will code it out for me if I blank it out! He thinks my DPF will fail shortly after though without the EGR

With an absence of exhaust gases and soot (oil vapour + particulates) flowing through the inlet manifold, inlet ports, and combustion chambers, you should notice smoother running, improved mpg, and (if it's been cleaned) no more fouling of the inlet manifold/ports.

I believe DPF regens are also tied into the throttle body and swirl flap operation, as well as the EGR valve / air mass detection.
That's why you have to choose your tuner wisely and only use one that has a lot of experience with diesel emissions controls. If you use decent fuel, do regular oil changes and do regular dual carriageway runs, the soot build up in the intake is nowhere near as bad as short journey only cars, which are also the ones more likely to have skipped services and cheapest, shittiest fuel used. |

There is no 'good delete kit', some are better than the others but the whole procedure is malicious and does lead to complications. Why do you need it out? Something being broken needs to be fixed and replaced by a proper part so it functions as intended. Moreover it technically downsizes exhaust levels which would be liable for paying more tax if it was factory standard. In fact EGR can be beneficial in helping to control combustion temperature smoothing engine work. In other words keep BMW a BMW.

An alternative view... Exhaust Gas Recirculation is a bodge as a cheap means of crudely reducing specific types of exhaust emissions as a result of ill thought out legislation. It introduces exhaust gasses and particulates into the combustion chamber, during specific operating conditions, as a means of reducing NOX, however...soot and exhaust gases, when mixed with oil vapour cause worsening deposits in the inlet manifold, inlet ports, and combustions chambers which are detrimental to the performance of the engine, can (often) result in noticeable and intrusive rough running (diesel clatter) due to overly-lean O2-fuel ratios at light load, reduce MPG, cause increased maintenance costs, require frequent visits to BMW for inspections and/or replacement of physical components (my EGR cooler has been inspected once, cleaned once, and replaced twice), and can reduce the overall life of the engine. If I forced you to wear a mask into which cigarette smoke was introduced when you were sedentary or exercising only mildly, with the justification that it would reduce the amount you farted, how would you respond ?

The EGR activates when needed for specific reasons. Its main function is to reduce NOx emissions, which is important and should be viewed positively, along with other useful functions such as controlling combustion temperature.

There is no rational engineering reason why one can't operate without the other. Morally I'm fine with DPFs but EGR just costs consumers a lot of money & hassle in unnecessary maintenance because Brussels are determined to rid the world of internal combustion engines, whilst they fly around the world to G5 summits in their private jets and Chauffer driven Rolls Royces. |

Because I have enough to put into your hat, take it off ASAP.

Decreasing the O2 available for combustion does indeed reduce combustion temps, and that can lead to a reduction in NOX, but I disagree that EGR is a a bona-fide technical/engineering approach to the solution. There are multiple negatives associated with EGR, and they could be negated if engine manufacturers invested in proper development rather than cheap (but disastrously expensive for them, i.e. BMW) bodges.

Yep. You've hopped into the Rabbit hole now. It'll be hybrid ball bearing turbos, downpipes, injectors, intercoolers and all sorts now! |

I’ve ordered a rebuilt OEM turbo for £335 and you have to send them your old turbo for exchange! Once you remove the emissions devices though the car will be in limp mode and won’t go over 2000 RPM but apparently still safe to drive for the engine. I’m Gona fit all the parts and limp up the motorway to dark side for re tuning hahaha! £600 for a tune and DPF and EGR software delete though 🤯🤯 He said I can retain my gearbox tune though and won’t need to re do it, can only imagine how much they would want to do both 😂 Don’t trust the guy who tuned it the first time tbh I’m not even convinced he actually put it on a dyno because he wouldn’t let me stay and watch for “Insurance purposes” |

I guess BMW have done something to hardcode the EGR and DPF together which can't be defeated in the aftermarket, perhaps more so on the Euro6 LCIs. It's all shrouded in mystery. Hopefully the rebuilt snail will sort your oil consumption out! Yeah the classic insurance purposes trick. Just means you can't see him uploading a generic map he downloaded off the internet and nothing more |
